[PVE-User] Moving from XenServer to Proxmox... slowly

[Kurt Bauer]

Hi,

we did pretty much the same thing over the past weeks, ie. changing fom
XEN to KVM (Proxmox) reusing the hardware already in place and
production. But we didn't went down the 2-Node cluster road, what we did
instead was, that we used an old server machine as a third node, just
for the sake of quorum and not having to deal with all the problems,
that may occur on a 2-Node cluster. No guests on that machine and as
soon as the 3rd production machine was free, we added it to the cluster
and removed the old one.
I guess performance is not an issue for that 3rd machine, as long as it
has no guests.

Hope that helps a little,
best regards,
Kurt
