Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Yesterday I upgraded my vCenter to the last version 5.1 and I had to reconnect the hosts (running esx 5.0, last patches)

Since I migrated, 5 vms (always the same) are vMotionned from host to host and when it's done it vMotions again to another host... (I can see in the task that DRS launched this operation) and then vMotion again and again

My hosts have enough free memory and enough free CPU on every hosts...

Should I be worried?

Thank you

Philippe

What level of DRS automation is set. –  Chopper3 Sep 14 '12 at 8:50
    
Fully automated and the cursor is set to "Aggressive" –  DJYod Sep 14 '12 at 10:45

I've only got 5.1 in labs and use the next level up from aggressive (the second one, can't recall the name) but haven't seen that behaviour, maybe they changed the thresholds with 5.1 to be super-aggressive? either way you have the option to move it from aggressive to a lower level, I'd try that first. –  Chopper3 Sep 14 '12 at 10:48
    
So I set the Migration threshold's cursor to the minimum (Conservative)... There are two clusters in my farm, only on of them is having this issue. Weird –  DJYod Sep 14 '12 at 10:53
    
I'd put a case in with VMW to be honest, they'e very good I find. –  Chopper3 Sep 14 '12 at 11:01
