Re: [libvirt] [PATCH 4/4] Enable support for systemd-machined in cgroups creation

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; Make the virCgroupNewMachine method try to use systemd-machined first. If that fails, then fallback to using the traditional cgroup setup code path. Signed-off-by: Daniel P.
