Getting Ovirt self hosted engine up and running on Ovirt node is even easier and the preferred operating system of choice. It is basically a trimmed down version of CentOS 8 with just the bits needed to run the Ovirt platform.
To get started we will download and install the latest version of Ovirt node from the Ovirt website.
Once we have the base OS installed and ready we just need to login and start the installation process.
tmux sudo hosted-engine --deploy
Follow along and answer all the question prompts. It will take the install process awhile depending on hardware specs.
We will be using CentOS 8 as our base operating system to install Ovirt v4.4.0 self hosted engine today. As a matter of fact CentOS 7 is not supported as a base OS starting with version 4.4.0 and future revisions. So once we have our OS installed, let’s start by making sure we are up to date.
sudo yum update -y && sudo yum install tmux -y
To install Ovirt 4.4 we need to setup the repository to install it and all of it’s dependencies.
Now that we’ve got our NFS storage all configured and ready to go from the previous post; let’s install Ovirt 4.3.10 on CentOS 7. I’ll be using the self hosted engine install option and of course NFS as our storage domain provider.
As always we are starting with the latest updates for our base OS, CentOS 7 in this case. I’ll detail the CentOS 8 install in an upcoming blog post soon. It’s very much the same process with minor changes.
sudo yum update -y && sudo yum install -y screen
To install Ovirt we need to setup the repository to install it and all of it’s dependencies.
While diving into Red Hat virtualization, I wanted to do some nested virtualization on my Intel NUC. In order to do nested virtualization on RHV 4.3 there are a few things you must configure. Please note that this feature is in tech preview currently.
In order to enable nested virtualization in RHV. You will need to pin the VM that you want to use it on to a particular host and disallow migration of that VM using live migration features. For me since this is a single NUC.
When building a new virtual machine or editing an existing one you will be looking at a screen that looks like the one below. Click on the ‘Host’ tab.
After you click on the host tab you will be looking at a screen similar to the screenshot below. You will want to pin the VM to a particular host, set the migration mode to Allow manual migration only. Once this is completed the Pass-Through Host CPU button will be enabled for use.
Now you will be able to do nested virtualization inside that particular VM. Repeat for any additional VMs you would like to have nested virtualization enabled.
