[libvirt] [PATCHv2 2/3] virsystemd: Don't fail to start VM if DBus isn't available or compiled in

On hosts that don't have the DBus service running or installed the new systemd cgroups code failed with hard error instead of falling back to "manual" cgroup creation. Use the new helper to check for the system bus and use the fallback code in case it isn't available. --- src/util/virsystemd.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/util/virsystemd.c b/src/util/virsystemd.c index 251b846..1c41ffc 100644 --- a/src/util/virsystemd.c +++ b/src/util/virsystemd.c @@ -145,8 +145,8 @@ int virSystemdCreateMachine(const char *name, char *username = NULL; char *slicename = NULL; - if (!(conn = virDBusGetSystemBus())) - return -1; + if (!(conn = virDBusHasSystemBus())) + return -2; if (privileged) { if (virAsprintf(&machinename, "%s-%s", drivername, name) < 0) -- 1.8.3.2
