This overview covers the key steps for installing Red Hat Enterprise Linux 8 so you can get started with software development. Instead, this tutorial provides an overview of the key steps for software developers. For detailed instructions, see the RHEL 8 documentation.

Unlike prior versions of RHEL 8, there are no separate downloads for server, workstation, or desktop. Your Red Hat username and password. Your account was created during step one. You will need this to register the system and attach it to your subscription.

Completing these steps are required for your system to download software from Red Hat. Before creating the VM, you may need to create a virtual switch. If you don't have the default switch, or prefer a different network configuration, create a new virtual switch and make sure it is attached to the external network. Next, you will need to change the secure boot settings.

During the boot process, do not be alarmed by log messages that briefly flash reporting errors. They will clear within a second or two. Note: During boot, you can skip the media checking step by hitting the Esc key.

Note: if your system only has one disk and you are using the whole disk for the installation, just click Done. Then, uncheck Enable Kdump. Next, configure the Network and optionally set the host name. Note: If you do not enable the network adapter here, you will not have network connectivity when you boot the system.

While the installation is proceeding, click Root Password to set the root Administrator password. Next, create the regular user ID that you will use to log into the system by clicking User Creation. This will enable sudo for your user ID. If you have a machine or VM that reboots too quickly to eject the installation media, you can try:.Note: This article was originally published on May It has been fully updated to be current as of August Microsoft continues turning greater attention to Linux.

We can now run PowerShell on Linux, we can write. Linux-on-Hyper-V has featured prominently on that list for a while now, and the improvements continue to roll in. If you have an organizational need for a particular distribution, then someone already made your choice for you.

However, there are many other popular distributions available and I like to branch my knowledge. One of the reasons that I chose Ubuntu was its ownership by a commercial entity. However, I also know from experience that relatively few administrators ever call for operating system support.

The ones that will make such a call tend to work for bigger organizations that pay for RHEL or the like. The rest will call some sort of service provider, like a local IT outsourcer. With that particular need mitigated, CentOS has these strengths:. Essentially, that means that someone decided that a particular package adequately measured up to a standard. The default CentOS repositories are not large when compared to some other distributions. They do not contain recent versions of many common packages, including the Linux kernel.

However, the versions offered in the CentOS repositories are known to be solid and stable. Linux is easy because pretty much everything is a file. There are only executables, data, and configuration files. Executables can be binaries or text-based script files. So, any time you need to do anything, your first goal is to figure out what executable to call. Configuration files are almost always text-based, so you only need to learn what to set in the configuration file.

The Internet can always help out with that. The Internet can help out with that as well. You can download CentOS for free from www. From either of those, you reach a page with a few packaging options. I would say that if you have a Torrent application installed, choose that option.

It took me quite a bit of hunting to find a fast mirror. These are my guidelines:. The following is a sample script that you can modify to create a Linux virtual machine in Hyper-V: You can find a more polished edition in my GitHub repository. You could also use your first installation as the basis for a clone.

It will run through several startup items, then it will load the graphical installer. Choose your language:. Wait a moment for it to detect your environment. As an example, the screen initially shows Not Ready for the Security Policy.

I am relatively new to Linux so please bear with me, the VM is a test machine to get the hang of things and give Ubuntu a try. One of the new features of Server R2 is the improved display capabilities as mentioned here at blogs. I don't think I am alone in finding this doesn't "just work". Some advice found online suggests updating the kernel, which I have done to 3.

In both cases I could only see resolutions listed under the display options up to xwhich is what Linux has always been limited to under Hyper-V. This has not given the option for the full x resolution either, and at this point I have run out of things to try and would not know if this is now a Hyper-V issue or something more fundamental and this would not have worked on a physical or other hypervisor machine.

I had the same issue and when I was looking for help I remember seeing your post. Now when I finally got it to work I might as well document it here:. Upgraded linux-image and headers sudo apt-get install linux-image Installed linux-image-extras with the hyperv-drivers: sudo apt-get install linux-image-extra-virtual.

I guess the critical part was installing the updated hyperv-drivers with linux-image-extra-virtual. Also make sure they are loaded. With the methods described, it didn't work for me. I hope that this solution helps you. In case of questions, please contact me and I will try to help. Ubuntu Community Ask!

This implies saving resources by not having to invest in the purchase of new equipment, greater security by not affecting at any time the productive environment of the organization or the physical equipment if we use it in our home.

Best of all, you can fully explore each of the new features that are integrated into new systems or applications. There are several virtualization platforms, but for this purpose TechnoWikis will talk about a particular one created by Microsoft such as Hyper-V. Next we will teach you how to install CentOS 8 there and thus know each of its functionalities.

Thanks to the implementation of virtual machines, we will be able to reach our full use potential.

Please log in or register to answer this question. What is Hyper-V? Hyper-V has been developed by Microsoft as a feature of its operating system thanks to which we have the advantages of hardware virtualization allowing the created machines to run with virtual hardware. In this aspect Hyper-V gives us the opportunity to create virtual hard drives, virtual switches and many more so that the user experience is identical to being on a real computer.

Some of its main features are: Quick creation and access to the VM gallery Default network NAT switch Hyper-V Replica Function Possibility to share files between the virtual machine and the physical equipment and more. Some of the new features of this edition are: Web console improvements Cockpit New container tool New Systemwide crypto policies TCP improvements New integrated package updates. There we can check the box "Store the virtual machine in another location" to define a custom route.

Later, TechnoWikis will explain how to configure a virtual switch to allow communication with the network. Nano is one of the most versatile text editors for functions and simplicity of use and is ideal for editing various system files, for its installation we must execute the following: yum install -y nano. These are a set of tools that allow us to expand the capabilities of the platform to the maximum, for this we will execute the following: yum install -y hyperv-daemons.

In this chapter of CentOS Essentials we will cover the steps necessary to adjust the display device and resolution of the GNOME desktop and configure multiple monitors. The first step in configuring monitors involves setting the optimal screen resolution for both the monitor and the user. CentOS will generally do a good job of configuring these settings during installation, but it can sometimes be necessary to modify these settings to obtain optimal results.

If the resolution menu allows you to make a selection that matches the maximum resolution capability of your hardware then make the appropriate selection and click Apply to commit the changes.

If, on the other hand, the maximum resolution available is less than your hardware is capable of displaying, it will be necessary to manually configure your display and graphics card settings. Note that since CentOS considers this as configuration change, as opposed to preference setting, the root password will need to be entered before proceeding. Select the Hardware tab to specify the monitor and video card settings so that they match your physical display hardware.

In the case of the monitor, this can be configured using one of the generic CRT or LCD settings, or by manufacturer and model by selecting the Show all available monitors option. Once these settings have been configured, select the Settings tab at the top of the dialog and select the new maximum resolution before clicking on OK.

A dialog will appear instructing you to log out and log back in again in order for the changes to take effect. On logging back into the system, the desktop should be displayed using the new resolution. CentOS supports dual monitors connected to a single system allowing the desktop environment and running applications to be spread over two screens.

If a second monitor is attached to the system, select the Use dual head option to enable the various configuration settings. Click on the Configure button to select the monitor type before making appropriate video card, resolution and color depth settings. If you would like each monitor to display its own desktop, select Individual Desktops.
