My VM was working last night but this morning I can’t display anything :-(.
virt-manager starts up okay but if I try to view (open) my VM it crashes. It does not matter if the guest is running or not, virt-manager
dumps core (according to systemd-coredump
). The log shows nothing untoward:
[Thu, 20 May 2021 10:15:32 virt-manager 2666] DEBUG (serialcon:17) Using VTE API 2.91
[Thu, 20 May 2021 10:15:32 virt-manager 2666] DEBUG (xmleditor:12) Using GtkSource 4
(crashes here)
Interestingly if I start the guest (select & press run) it starts up fine:
[Thu, 20 May 2021 10:18:53 virt-manager 2878] DEBUG (vmmenu:230) Starting vm 'win10'

and the CPU usage graph trickles along nicely.
But if I try to Open it… boom. It’s just virt-manager that crashes, however, the qemu process is still running…
ps ax | grep qemu
2924 ? Sl 0:55 /usr/bin/qemu-system-x86_64 ...
My system details:
Distribution: Clear Linux OS
Installed version: 34630
running on i5-8600K Prime Z370-P with GeForce GT 710 (Nvidia drivers) running three screens under XFCE.
Firstly - I think this is a bug, where should I report it?
Secondly, is there a command line tool I can use to connect to this process and try to force it to display, or at least get more detailed error reports?
Many thanks,
Jerry
PS: systemd reports that Avahi-daemon failed to load - is that relevant?
