role fails on debian: no available installation candidate for qemu-kvm

[DO1JLR]

Hi there.

Thank you for this Ansible role. Unfortunately this role throws the following error for me on Debian GNU/Linux 11 (bullseye):

TASK [libvirtd : Ensure libvirt packages are installed] ************************************************
FAILED - RETRYING: [example.com]: Ensure libvirt packages are installed (3 retries left).
FAILED - RETRYING: [example.com]: Ensure libvirt packages are installed (2 retries left).

  msg: no available installation candidate for qemu-kvm

If I adjust the libvirt_host_libvirt_packages_common: variable under vars/Debian.yml and install the package qemu-system-x86 instead of the Debian package qemu-kvm, the role runs through without complaining.

You certainly know this, but the qemu-kvm package is a "virtual package". See packages.debian.org/bullseye/qemu-kvm.
