> Ran into an interesting problem today. Topology is a 4-Node Cluster on v.5.2, been up and running without issues for 10 months or so. Several VMs running on node 1, 2 & 3, maybe 30% loaded. I keep node 4 empty for HA and new build VM testing. All VMs are set for HA and auto start on node reboot.

I tested this scenario in the lab  running PVE 5.4-7 and cannot
reproduce the original symptoms above. I manually set 1 node hardware
clock +1 hour, rebooted and when it came back up, the system time and
hardware clock synchronized to correct time within a minute or so and
VMs started up OK.

So my question, is there a startup routine in PVE 5.4-7 that
synchronizes system and hardware clock shortly after boot up that was
not present in PVE 5.2?

Thanks.
