Update: I don’t know why, but after i downgraded/updated libvirt and libvirt-phyton serveral times, the problem is gone…strange
Since the update I have a problem with virt-manager/KVM/QEMU when running a VM with MXLinux as guest.
A short time after logging into the VM and starting Xfce (less than 1 min), the Virt-Manager viewer loses the connection to the VM and closes. The VM itself continues to run in the background. When I reconnect virt-manager to the hypervisor and open the viewer again, the same thing happens shortly afterwards.
If i do not login and change to another tty everything is fine.
Logs of the guest are fine.
I tried to downgrade libvirt and libvirt-python to 1:10.4.0-1 and 6.6 LTS Kernel but same result.
