Hi,

Could you please share more details about the CPU problem you're facing? There shouldn't be any breaking change in that CPU definition in 4.4+ compatibility version.

Regards,

Lucia

Having updated rpm-packages for a DC with a cluster containing 2 hosts
(and executed the engine-setup on the engine machine), I now face the
following issue:

One of the VMs had a couple of snapshots and apparently this interferes
with the upgrade of the cluster version, which currently is 4.4.

The 4.4 has become incompatible with the chosen CPU architecture (Intel
Westmere Family, the hosts are both Dell x10-series with Xeon X56xx
CPUs) and requires an upgrade to newer compatibility version, 4.6
presumably, so the DC/Cluster state is "unknown". However I can't do
this because the snapshots exists. I get the "Cannot change cluster
version since following VMs are previewing snapshots:" listing a VM with
snapshots. The snapshots in turn can not be Commit/Undo because: "Cannot
revert to Snapshot. Unknown Data Center status.".

So how do I break this circular error? The VM itself is not essential,
it can be removed if that solves the case. However this can not be
completed from the UI because: "Cannot remove VM. Unknown Data Center
status.".
