Latest Qemu Installation in Debian Bullseye – Step-by-step

Getting Started

7. 7. Installing Libvirt

   Now to Install Libvirt for Debian
   Simply play:

   sudo apt install libvirt-clients libvirt-daemon-system bridge-utils ipxe-qemu libcacard0 libexecs1 libfdt1 libiscsi7 libnfs13 librbd1 libslirp0 libspice-server1 libusbredirparser1 libvdeplug2 libvirglrenderer1 ovmf

   Following Debian Documentation about KVM related Packages:

   • libvirt provides libvirtd which you need to administer qemu and kvm instances using libvirt
   • bridge-utils provides a bridge from your network to the virtual machines

8. 8. Adding User to Group

   Next Add User to libvirt Group
   First, you need to Make the Group:

   sudo addgroup libvirtd

   And then Add User with:

   sudo adduser `id -un` libvirtd

   This because only the Users of this Group can Run Virtual Machines.
   Then Relogin to Enable this Setup!

9. 9. Verifing KVM Installation

   Finally, Test Installation.

   Simply performing:

   virsh list --all

   And in the Output you should find:

    Id    Name                           State
   ----------------------------------------------------

   This because still no VMs has been made.
