[Pkg-libvirt-maintainers] Bug#1011518: libvirt-daemon: libvirtd does not load the KVM module automatically

[Chandra Sekar]

Package: libvirt-daemon
Version: 8.3.0-1
Severity: important
X-Debbugs-Cc: chandru.in at gmail.com

Dear Maintainer,

libvirtd used to load the appropriate kvm module automatically on
startup, but appears to have stopped doing so with the latest update. I
see the following lines in the output of sudo systemctl status libvirtd.

libvirtd[1122]: Unable to open /dev/kvm: No such file or directory
libvirtd[1122]: internal error: failed to query mdevs from mdevctl: Error: No such file or directory (os error 2)

I have verified that virtualization is enabled in firmware settings.
Restarting libvirtd after loading the kvm-amd module using modprobe
resolved the issue.
