Install homeassistant on OpensuseLEAP KVM QEMU

Hi everyone, I have an intel n100 PC with raid storage, everything works perfectly…
Forgive my bad English in advance.
Basically I have to install homeassistant but I think it is much easier to manage the VM than the container because it is easier to backup and restore it if necessary.
I wanted to install it on opensuse LEAP, I also installed cockpit there but unfortunately the qcow2 image cannot boot via KVM cockpit.
Could you give me some advice?
