VirtManager libvirt.libvirtError: internal error: process exited while connecting to monitor - linux

Question

I am using Archlinux with virt-manager and kvm. When I conifgured like this and I got these errors below. Can somebody help me solve it? Thank you a lot!
Configration of Display Spice
Configration of Video Virtio

libvirt.libvirtError: internal error: process exited while connecting to monitor
And I found these in /var/log/libvirt/qemu/$MYGUESTNAME.log, but I cannot figure out what's wrong with it.

Answer 1

That is a sign that QEMU has unexpectedly crashed. if you are lucky there will be more useful error information in /var/log/libvirt/qemu/$GUESTNAME.log that will help you diagnose the problem
