Going Into Production With Windows Server 2008 R2 Hyper-V Cluster

I’m happy enough now with our W2008 R2 Hyper-V cluster that I’m putting it into production tomorrow night.  We’ll be migrating some of our production machines from the old W2008 cluster to the new cluster.  Today I deployed OpsMgr agents onto the hosts and did some more testing.

OpsMgr and VMM don’t synchronise their maintenance modes.  I submitted feedback suggesting that this would be good.  I also noticed that even if both System Center products had a node in maintenance mode, the VMM management pack would alert when that node rebooted.  Ouch.  That’s a bit painful.  I also submitted feedback on that.

So far, I haven’t had any problems with CSV or Live Migration.  Everything has worked fine.  One tip I’ve picked up on is to set a static MAC on Linux guests.  SUSE 10 SP2 binds the IP configuration to the MAC address and a change due to any sort of VMM/Hyper-V migration can screw it up – I’ve seen this with an export/import.

So 11PM tomorrow, the first production machine moves over, followed by the second at midnight.  Hopefully there won’t be any calls on Saturday morning!
