Re: [libvirt] [PATCH 2/2] vircgroupv2: fix virCgroupV2ValidateMachineGroup

When libvirt is reconnecting to running domain that uses cgroup v2 the QEMU process reports cgroup for the emulator directory because the main thread is in that cgroup. We need to remove the "/emulator" part in order to match with the root cgroup directory name for that domain.
