High CPU usange for VMWARE Guest virtual machine
Posted on 2007-04-08
This question is related to VMWARE. I have Windows 2003 SP2 as the HOST. On the guest OS, I have Windows 2003 SP2 R2.
I started to notice terrible performance everytime I stated the Guest OS. I monitored them carefully and tried to start with just one guest at a time. The vmware-vmx.exe task that is running the windows 2000 server constantly uses 25 of the host system, even if the guest shows zero cpu and nothing is running on it. Furthermore, I also see the followings:
"System Idle process" = 90%
"DRWCS.EXE" = 30-40%
This is the case for any of the guest OS. The server we are testing it on is Dell 2650 Dual 2.4Ghz, 6GB RAM. I tried setting the guest to 512MB (from 2GB). Still same problem. Any ideas on what could be causing this?
