Re: [libvirt] [PATCH] cgroup: Don't fail to start a VM when DBus isn't compiled in or running

The systemd code to create cgroups has fallback means built in, but fails to engage them if a host isn't running DBus or libvirtd is compiled without DBus (yes, you still don't need to run DBus). This patch changes the return value in case DBus isn't available to so that the fallback code can be activated and cgroups are created manually. --- src/util/virsystemd.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-)
