Re: [PATCH 1/2] apparmor: Allow lxc processes to receive signals from libvirt

LXC processes confined by apparmor are not permitted to receive signals from libvirtd. Attempting to destroy such a process fails virsh --connect lxc:/// destroy distro_apparmor error: Failed to destroy domain distro_apparmor error: Failed to kill process 29491: Permission denied And from /var/log/audit/audit.log type=AVC msg=audit(1606949706.142:6345): apparmor="DENIED" operation="signal" profile="libvirt-314b7109-fdce-48dc-ad28-7c47958a27c1" pid=29390 comm="libvirtd" requested_mask="receive" denied_mask="receive" signal=term peer="libvirtd" Similar to the libvirt-qemu abstraction, add a rule to the libvirt-lxc abstraction allowing reception of signals from libvirtd.
