In order for the guest operating system (or virtual machine operating system) to do this, the virtual machine must assume a shared folder similar to the network share folder and build it there.

After that, the guest operating system can look like folders Internet sharing also has access to the folder created on the PC.

VirtualBox Virtual Machine

As mentioned in the introduction, you must create a shared folder between the two operating systems to access files. The Shared Folder feature works on VirtualBox virtual machines and on both Windows and Linux guest operating systems alike.

To use it, you need to install a Guest Additions on your virtual machine guest operating system. Click on the Devices tab and then click Insert Guest Additions CD image while the virtual machine is running and start installing it on the virtual machine.

After installing,

click on the Machine upper tab, go to Virtual Machine Settings and select Shared Folders. Here you can see any shared folders you’ve already created.

But if you haven’t done so already: In this section you will find two types of shared folders, the first of which is Permanent Folders, which will share files until they are deleted as a shared folder.

The second type are temporary folders (Transient Folders) that are deleted as soon as the virtual machine is restarted or turned off.

Here you can click on the Add or Add button to add a new shared folder or right-click on an existing list and select Add Shared Folder .

The path to the created folder is the one where you are given the address and with the name you selected will be placed on the host operating system (the main operating system you have installed on your system).

By default the virtual machine provides full read / write capability for the shared folder.

But if you want to restrict the freedom of the virtual machine and the operating system on it can only read the host operating system files through the shared folder or not allow file transfer or file creation, read-only.

Also, if you check the Auto-mount option, the guest operating system on the virtual machine automatically activates the folder sharing feature each time you boot.

The Make Permanent option also prompts the shared folder to become the default virtual machine folder (always present).

If you are running a Windows operating system on a virtual machine (as a guest operating system), you should see a shared folder as a network share file.

Open the Windows browser (in Windows 8: This PC) and select the Network section as shown below and look for VBOXSRV.

You can also mount this folder with a few commands.

Do this using the following command in Windows and paste NAME with your subscription folder name:

  net use x: \\ vboxsvr \ NAME

Use the following command on Linux and use the folder name instead of NAME. The / mnt / folder path is also the directory of the shared folder.

It should be noted that you must have created the folder before using this command.

  mount -t vboxsf NAME / mnt / folder

VMware Virtual Machine

Shared Folders feature on Vmware virtual machine can also be created on both Windows and Linux operating systems. But first you need to have VMware Tools installed on your virtual machine before you can use this feature.

In the Virtual Machine menu you should find the option to install or update the VMware Tool (if your version is not the latest version you should update it).

Then go to the Virtual Machine Settings window:

For example, in the Vmware Virtual Machine you will need to select the Player tab from the top, go to the Manage section, and then click Virtual Machine Settings.

You can access this feature (shared folder) by clicking on the Options tab and selecting Shared Folders.

Add the folder you want to share from.

All of these folders will be displayed in the virtual machine with the name you selected. By default, Vmware VMware gives you full access to read / write files.

But with the Read-only option like the previous virtual machine

you can deprive the machine of the ability to write inside the folder.

A shared folder similar to the Internet network sharing folder will appear on the guest operating system Windows. It can be found under the name vmware-host.

You can increase the speed of transfer and use of the sharing folder by ticking “Map as a network drive in Windows guests”.

 And instead of looking for shared files on the network,

the file sharing folder using this feature has a special drive and is displayed in your computer’s drive window.

If you are using a guest Linux operating system,

then you should find the Vmware subscription directory in the / mnt / hgfs / root directory.

Keep this in mind;

if you use multiple virtual machines then you must share a folder for each. You also need to be very careful when using shared folders,

because if your virtual machine is at risk of a virus,

the virus can get out of the virtual machine and infect the contents of the shared folder.

Virtual Machines (Vms) allow you to run other operating systems on your current operating system. The virtual operating system runs like a program on the main operating system of a computer.

This feature is ideal for testing other operating systems such as Windows 7 or Linux operating systems.

The virtual machine is also used to run software not designed for the main computer operating system.

For example, running Windows applications on a Mac with the help of a virtual machine.

Interested in working with virtual machines? You don’t have to pay for this. There are many virtual machines that are offered with great power for free.

What is a Virtual Machine?

A virtual machine is a program or software that runs on a virtual computer. The machine runs on the host or host operating system and prepares virtual hardware for guest operating systems.

The guest operating system, like any other application, runs on the main operating system in a separate window. From a guest operating system perspective, a virtual machine is a real computer.

Virtual machine virtualization software, called a hypervisor, uses virtual hardware including processors, memory, hard drives, network interfaces, and other devices.

Virtual hardware tools are provided with the help of a hypervisor map for real hardware on the computer. For example, a virtual hard drive is stored on a file on the hard drive.

Multiple virtual machines can be installed on one system. The only limit on their number is the amount of space available for installation.

When you have multiple operating systems installed, you can choose one to boot by opening the virtual machine. The virtual operating system starts and runs in a separate window.

Of course, it can also be run full-page.

Practical Applications for Virtual Machine

The virtual machine has a variety of general applications:

Testing the new version of the operating system

You can run and try Windows 8 on Windows 7 before using Windows 8 before updating to Windows 8.

Experience the space of other operating systems

Installing multiple versions of Linux on a virtual machine allows you to experience all of them and learn how to work with them.

Deploying software that requires older operating systems

If you have an application that runs only on Windows Xp, the problem is with installing Windows Xp on the virtual machine and running the program on it.

Virtual Machine provides an environment where you can run Windows Xp software without actually installing Windows Xp on your computer.

Especially since Windows Xp no longer receives Microsoft support.

Run software designed for another operating system

Mac and Linux users can boot Windows into a virtual machine so they can run Windows software without the hassle of compatibility. Unfortunately, we have trouble running games. Heavy-duty 3D games in a virtual machine are not as smooth and comfortable as real Windows.

Testing software on different platforms

To test the functionality of a particular software on different platforms, you can install and test it on multiple platforms with the help of a virtual machine.

Server integration

For businesses that use multiple servers, multiple servers can be run on one computer on multiple virtual machines.

Every virtual machine is a completely separate server, so it doesn’t have any security issues that usually involve running multiple servers on the same operating system.

Virtual machines also have the ability to switch between physical servers.

Recommended Virtual Machine Software

VirtualBox is a great open-source virtual machine program that runs on Windows, Linux and Mac OS. One of its best features is the lack of a commercial version.

This also means all the advanced features like snapshots for free use. This feature is suitable for storing a specific location and mode of the virtual machine and returning it for future testing.

Vmware player is another well-known virtual machine program in Windows and Linux. The Vmware player is the free counterpart of the commercial Vmware workstation software. So we don’t include the advanced features that VirtualBox provides.

However, both the above software are applications that provide some basic features for free. If you are not comfortable with one, try another.

Run an operating system on a virtual machine

To install an operating system on a virtual machine, you will need an operating system CD. Creating a CD for Windows 7 installation makes it easy.

An ISO file can also be used, which is often used to install Linux. Virtual machine applications provide simple and useful wizards that guide you through the steps of creating a virtual machine and installing the guest operating system.

Virtual machines are not limit to the desktop operating system, and even on Android you can run the Video 8 Virtual Machine.

On the one hand, there is a good similarity between data and oil. Both industries have enormous environmental impacts. The US Department of Energy, for example, claims that datacenters account for about two percent of US electricity consumption.

The environmental impact of data services industry indicates that cloud services, such as applications such as Netflix content delivery, online gaming or even email, do not have a metal or copper infrastructure, and therefore carbon should be their primary source.

Cloud Services For ordinary users, the environmental impact of their services may not be so obvious, but their digital impact can, however, increase the impact on the environment. Finding the cleanest and healthiest way to store data can reduce the environmental impact and greenhouse gas emissions of cloud services. But how do wealthy companies and their owners think about such issues?

The answer to this question is never clear.

The three major cloud service providers – Amazon AWS, Google Cloud, and Microsoft Azure – account for two-thirds of all cloud computing services. In their approaches, they claim to be trying to implement the cleanest solutions. Zoomit’s current article is a translation of Wireless Media’s review of corporate claims and cloud-based solutions.

How do cloud services get cleaner?

Some companies are still storing their data in black boxes in large cabinets of data center corridors, which always have flashing lights. The needs of some other datacenters have been so great that they have forced them to build dedicated datacenters. For businesses in the middle of the two, there are generally no more than three solutions. They have to pay either Amazon, Google, or Microsoft to store the data on the aforementioned giant server farms.

Jonathan Kumi, an environmental expert examining the cleanliness of diverse cloud services, considers three factors: the efficiency of datacenter infrastructure (lighting, cooling and the like), the efficiency of servers, and the power supply.

Each of the three major cloud service providers has reduced performance reductions in their hardware and software to some extent. They use virtual machines on their servers to reduce downtime. Dedicated cooling systems are used in servers and automation is implemented in all areas.

Professional methods of increasing efficiency in the past few years have led the data center industry to maintain its energy needs somewhat stable over the past decade.

In addition,

increasing the efficiency of datacenters means that when individuals and organizations transfer data from internal servers to the cloud, they will reduce their energy consumption.

According to Berkeley National Library scientist Dale Sartre, the efficiency and power consumption of massive datacenters will not remain the same. In his view, one day we will reach the climax; the climax will be when all organizations have moved their datacenters to service companies. At that time, the energy demand for datacenters is starting to increase. On increasing energy consumption, Dale says:

No one imagines that our growth in processing resources will slow down. As a result, the likelihood of an explosion in energy consumption will be high in the next one to two decades.

Considering the above hypotheses, one of the best ways to measure the cleanliness of a datacenter is to check its energy source. All three major players claim to have made every effort to stop carbon in the datacenter, but none have yet managed to completely eliminate fossil fuels.

Companies with the Token REC make a claim of 2% renewable energy

Big cloud companies rely on a tool called renewable energy credibility to clean up their carbon footprint on the environment. The tool is Token (REC), which represents the company’s clean energy production.

In fact, REC allows companies such as Google and Microsoft to claim renewable energy consumption while still being connected to fossil fuel-based power distribution networks.

Ultimately, only part of the energy of each company comes directly from sources such as wind and sun , and the rest will be based on REC.

Calculating the cleanliness of cloud services is replete with subtle differences between factors. However, here are some important factors that will be helpful in calculating carbon offsets in data storage.

Google Cloud

Company claim

Google has the smallest market share among the three major cloud players, but has made the most of its efforts to reduce carbon emissions from data storage. Mountain View residents announced in the year 2 that they have achieved 3 renewable energy uses in all their activities, including datacenters. They claim that all data processed by Google Clouds has zero carbon emissions.

How to do it

Google considers itself the largest buyer of renewable energy in the world. In September, they increased their renewable energy portfolio by 5% with energy purchasing contracts around the world. Such contracts are meant to provide the capital needed for renewable energy projects that use their energy once the project is completed. The main idea behind such plans is to develop renewable energy distribution networks developed by Google.

In addition to renewable energy applications, Google uses machine learning to optimize its datacenters. For example, the algorithm you teach with climate history data has the ability to control the temperature of the datacenter in a variety of environmental conditions.

Joe Kawa, Google’s senior vice president of data science, describes how the algorithm works. The system protects different climatic conditions every five minutes so that, if severe ambient temperatures drop, the datacenter infrastructure will devote less energy to cooling the servers.

System achievement

In 2008, Google launched a special oil and gas subcommittee with the explicit aim of attracting the fossil fuel industry. The company claims that its machine learning tools, combined with cloud services, will help oil and gas companies perform better with their data. In other words, Google helps companies extract oil and gas more efficiently and quickly from existing tanks.

It is worth noting that Google uses fossil fuels in its datacenters in areas of the world with little or no renewable energy. Of course, with the preparation of REC, they cancel the effect of those fuels.

Upcoming Plans

Google Cloud prepares its carbon consumption calculations on an annual basis globally. They calculate energy consumption and supply and purchase of renewable energies and make sure they have equal value. Kava says Google is trying to make data centers have 1% renewable energy consumption over one hour. Such a claim is ambitious because resources such as the sun and wind are not always available, but the Internet power plant must always be on. Such an approach will not only require more renewable projects, but will require more technologies, and long-term energy storage is one of the key issues.

Google’s datacenter and artificial intelligence teams work to optimize datacenter energy consumption

Better use of current renewable technologies will enable us to develop them better in the future. The Google Datacenter team partnered with Deepmand’s artificial intelligence unit earlier this year to develop a machine-learning model that can predict wind farm output up to 6 hours in advance. Using this information, organizations can better plan for energy availability to increase the wind energy available in the distribution network.

Microsoft Azure

Company claim

Microsoft has a slogan, “Erase DataCenter,” where it strives to bring the environmental impact of its server farms to zero. The Radomonds have had neutral carbon consumption since year 6 and, relying on REC tokens, have increased their performance by 5% on renewable energy since year 2. Microsoft’s datacenters, regardless of REC, do only 5 percent of their renewable energy. They plan to increase the figure to 5% by the year 5.

How to do it

Microsoft has significant domestic policies such as a domestic carbon tax. Such policies require all departments, including Ajour, to maximize their environmental impact. The Red Wings have also invested heavily in clean energy. They signed a clean energy deal in Washington earlier this year and are planning to buy their own electricity from a new farm in the state. Microsoft has also signed a contract for a solar power project in North Carolina.

Brian Janus, general manager of Microsoft Energy and Sustainability Projects, says the company’s new projects in the field of renewable energy supply will bring their portfolio to 1.5 GW. The figure shows a growth of about 2 percent from last year.

Microsoft is investing in research to increase energy efficiency in current and future datacenters. Last year, they launched a datacenter experiment on the ocean floor that would reduce or even reduce the cost of infrastructure cooling. Redmonds are also conducting experiments on fuel cells to power the datacenters.

Like Google, they use machine learning to improve the efficiency of their data center infrastructure. Other applications include providing credentials to researchers who are researching climate change issues.

System achievement

Microsoft is working with fossil fuel activists. In September, they announced a partnership with the world’s oil and gas giants Chevron and Schlumberg, aimed at using the Azure platform in a bid to “accelerate the production of innovative digital and petrochemical technologies.” The collaboration has angered a number of Microsoft employees who accused the company of complicity in the global climate crisis. Many Microsoft employees took part in a demonstration against the announcement of the collaboration.

Although Microsoft has renewed all of its activities since year 9, they still use fossil fuels. The use of fossil fuels, like others, is counteracted by REC tokens. Finally, it is worth noting that Redmonds are investigating the use of natural gas to power the datacenters. Although natural gas offers improvements in terms of energy efficiency, it is not in the category of renewables and in some ways increases the carbon footprint of the company.

Upcoming Plans

Janus says fuel cells are a way to convert datacenters into their own power plants because they generate electricity at the same site. They hope that someday hydrogen will become an abundant and inexpensive element to use as a fuel cell with the minimum carbon content. As mentioned, the cells are now being tested using natural gas.

The development of battery technology for datacenters is one of the major research and investment topics in Microsoft. Regardless of the fuel cell or battery, the nature of converting datacenter to energy storage improves the use of renewable energy. When solar and wind energy are available, they can be stored and imported into orbit at reduced times. The Redmonds started a pilot project last year using a battery in Datacenter Virginia.

Amazon AWS

Company claim

Microsoft’s cloud service subsidiary, wholly called Amazon Web Services, is recognized as the largest cloud provider in the world. AWS holds more than a third of the market share. CEO Jeff Bezos has announced a long-term commitment to achieving 2 percent renewable energy in the organization he manages. The company has since developed numerous wind and solar power plants.

Bezos had promised earlier this year to cut carbon emissions by zero by year two. His comments and plans came under pressure from numerous critics and staff. Amazon announced in year 3 that, considering REC tokens, renewable energy consumption across the organization would reach 5%.

How to do it

To date, Amazon has participated in numerous power supply programs that have led to the construction of three wind farms and four new solar farms in the United States. Numerous other projects are under construction for years to come. As mentioned earlier, Amazon, like other providers, uses REC tokens to neutralize carbon emissions.

System achievement

Earlier this year, Greenpeace accused Amazon of stopping its commitment to achieving 2 percent renewable energy. According to a report, some of the company’s largest datacenters operate with only 2 percent renewable energy. AWS in Virginia, which supports the core of Amazon’s cloud infrastructure, has increased its business by 2 percent over the past two years without adding new renewable energy. In response to the report, Amazon only claimed that it would abide by its commitment to achieving 2 percent renewable energy.

Amazon has adopted the habit of hiding information about its carbon footprint from the community. Although they released their first global carbon footprint report for the first time this year, they asked the Australian government not to publish the information in the country’s annual report.

In addition, there have been numerous criticisms of Amazon that target the failure to publish a clear roadmap for future plans on the path to achieving 5 percent renewable energy.

Finally, Amazon, like the other two providers, has partnerships with the oil and gas industry. They provide their companies with services as a way to accelerate and optimize fossil fuel extraction, drilling and production processes.

Upcoming Plans

Amazon did not respond to Wired on current or future AWS applications.
