+Subject: [PATCH] vircgroupv2: Fix VM startup when legacy cgroups are defined
+
+On Fedora 31, starting a 'mock' build alters /proc/$pid/cgroup,
+probably due to usage of systemd-nspawn.
+
+Before:
+$ cat /proc/self/cgroup
+0::/user.slice/user-1000.slice/...
+
+After:
+$ cat /proc/self/cgroup
+1:name=systemd:/
+0::/user.slice/user-1000.slice/...
+
+The cgroupv2 code mishandles that first line in the second case, which
+causes VM startup to fail with: Unable to read from
+'/sys/fs/cgroup/machine/cgroup.controllers': No such file or directory
+
+The kernel docs[1] say that the cgroupv2 path will always start with
+'0::', which in the code here controllers="". Only set the v2 placement
+path when we see that cgroup file entry.
+
