I've got a problem with vmtoolsd.exe consuming large amounts of CPU on a 2003R2 XenApp VM which I can't get to the bottom of.
Basically vmtoolsd.exe spikes to 40% every 30 seconds. As the machine gets more users on it (and hence more active memory) the duration of the spike increases until eventually the spikes merge into a continuous 40%. This renders the XenApp user sessions unresponsive.
Anyone got any ideas?
Sorry - should have posted up what I found.
It turned out the perfmon counters were corrupted during the conversion to a provisioned disk (To see if this is your problem, open perfmon & try adding a counter - if they all show up as numbers rather than names then they are corrupt). Fixing them has resolved my problem with vmtoolsd.exe.
