Advanced KVM management

Using KVM is so much more than just creating VMs and starting or stopping them. VM management can be much more complex, starting with VM automated installation, storage and resources management, and up to VM orchestration. Some of these topics are out of the scope of this book, but we will still show you how to master your VMs on your Linux-powered systems.

By now, we only have one VM. For the purpose of the exercises in this section, we will create two more VMs, all running the same Ubuntu OS that we used for the first VM. We will create ubuntu-vm2 and ubuntu-vm3 VMs using the following commands:

• For ubuntu-vm2:

  sudo virt-install --virt-type=kvm --name ubuntu-vm2 --vcpus=2 --memory=2048 --os-variant=ubuntufocal --cdrom=/var/lib/libvirt/images/ubuntu-22.04.2-live-server-amd64.iso --network=default --disk size=20 --noautoconsole

• For ubuntu-vm3:

  sudo virt-install --virt-type=kvm --name ubuntu-vm3 --vcpus=2 --memory=2048 --os-variant=ubuntufocal --cdrom...
