Bump,
Any Idea's?
Stephen
Are you using custom or default CPU share values for the VM's?
Try experimenting with increasing and decreasing the shares to see if things improve or worsen.
I had this problem in the following article, but applying update 1 fixed the problem: . It was working well for a couple weeks.
I just installed the patches that were released on May 1st and the DRS problem came back. 1 minute after I disable DRS everything is back to normal. I browse to the advanced setting of Mem.VMOverheadGrowthLimit and it is set at -1. Update 1 fixed this problem by making this setting a 5. The patches I applied removed the DRS fix that was applied in update 1.

Yes i think you are right the problem is back, it was fixed but with the latest patches it seems to be back.

Bump,
Does anybody else have this problem? the problem WAS fixed but now it's back with the latest patches.
Stephen
It's happening here too.
I just noticed http://kb.vmware.com/kb/1003638 says "Note: This issue is resolved as of VirtualCenter 2.5.0 Update 1". My ESX Servers are up to date, but my VC server is not.
I have already updated to update 1 for VC and ESX, this took care of the problem. but when the latest patches came out it broke it again.
Stephen
Bump,
How many people are having this problem after 4-30-08 patches? the problem was fixed when update 1 came out. then when i installed the 4-30-08 patches it broke it.

Speedbmp:
We were also experiencing the same problem on ESX cluster with the latest updates installed.
I found this discussion after spending a morning trying to figure out what on earth was going on - all VM's were performing extremely poorly due to high CPU usage after migrations. After reading this thread I disabled DRS and in a few minutes everything was running smoothly again! Later on I re-enabled DRS and haven't had any problems in a couple of days (I left DRS set to "partially automated" so no migrations so far until this is resolved for good).

Same problem here. Not all machines exhibit the behavior. All are using default settings, nothing custom. Fixed before patches, broken after patches.
Someone should teach vmware how to use snapshots as it seems they are constantly reverting their code after fixing something.
Either that or to use a code repository so they stop keeping multiple different copies of the code...
So whats the best way to get this fixed? call VMware or wait tell they issue another a fix next month?
Stephen
the trick that solved the problem for me was:
turning off HA and DRS on cluster
create new cluster
move ESX hosts to new cluster
move vm's to new cluster
turn on HA and DRS on new cluster
We opened a ticket with VMware and the end answer was they know the problem exists and it will be fixed in Update 2. No timeframe on the release date though.
I am glad they are aware of the problem. for right now i will just have to keep DRS disabled.

Would be useful if there was a method to uninstall vmware host patches.
True, it would also be nice to know which of the patches broke it.
Stephen
Indeed, though would be possible to find out if patches could be removed (albeit somewhat tedius).
