Re: [libvirt] [PATCH] virt-aa-helper: Fix permissions for vhost-user socket files

QEMU working in vhost-user mode communicates with the other end (i.e. some virtual router application) via unix domain sockets. This requires that permissions for the socket files are correctly written into /etc/apparmor.d/libvirt/libvirt-UUID.files.
