Hi,
i have a problem with virt manager losing the connection to my vm guest os after login into the guest. It happened occasionally in the past, but now it seems to be permanent.
I followed all guides i found so far:
added my user to libvirt-qemu and kvm in addition to libvirt,
uncomment the two lines in /etc/libvirt/libvirtd.conf
keepalive_interval = 5
keepalive_count = 5
Here the output of systemclt libvirtd and inxi:
systemctl status libvirtd

apart from that, the network widget looks weird:
but the network in system settings looks normal to me
any clues? I’m a litte desperate…
