Hi everybody,
my first post, pls go easy on me 
so, I use a lot of debian VMs in KVM for testing purposes
I clone the original machine, change the hostname and recreate ssh host keys through a set of commands (or script)
the goal is to automate this process using libvirt
the clone part is working but Iām unable to use virt-sysprep to do the rest
$ sudo virt-clone -o debian11 -n debian11-clone --auto-clone
$ sudo virsh list --all
Id Name State
---------------------------------
- debian11 shut off
- debian11-clone shut off
$ sudo virt-sysprep -d debian11-clone --hostname debian11-clone -v

This usually means your kernel doesn't support virtio, or supermin was unable
to load some kernel modules (see module loading messages above).

I tried to summarize the output, if the full output is more usefull please let me know how can i share it
the errors seem to be only from supermin/insmod
I have the following packages installed
$ rpm -qa | grep -i guestfs

acording to https://doc.opensuse.org/documentation/leap/archive/42.3/virtualization/html/book.virt/chap.guestfs.html
it should be working
is there a easy what to automate the process besides using virt-sysprep? (already tried using virt-costumize, got the same erros)
thank in advance
