A QEMU change (10218ae6d006f76410804cc4dc690085b3d008b5) introduced
some libnuma calls that require read access to
/sys/devices/system/node/*/cpumap, which currently is forbidden by the
standard apparmor profile.
This commit allows read-only access to the file specified above.
Closes #515
I always forget, but looking at the git log it seems the full URL is preferred. E.g.
Closes: https://gitlab.com/libvirt/libvirt/-/issues/515

It's a bug fix so should be safe for freeze. I'll make the above change to the
commit message and push it.
Regards,
Jim
