Cloudmin fails to setup KVM virtualization on new host

SYSTEM INFORMATION
OS type and version Ubuntu 22.04
Webmin version 2.010
Cloudmin version 9.7pro

Adding a freshly installed Ubuntu 22.04 kvm host system into Cloudmin fails with this error :

    .. installation failed : Reading package lists... Building dependency tree... Reading state information... Package kvm is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source W: --force-yes is deprecated, use one of the options starting with --allow instead. E: Package 'kvm' has no installation candidate

.. setup failed! See the error message above.

apt list kvm* show only a kvmtool package.
So I can’t add a new kvm host from fresh install :face_with_diagonal_mouth:
