This is somewhat of a longshot, but I am wondering if anyone might be able to explain the following:
I have a VMware Host Server running Ubuntu Server 8.04 LTS, and VMware Server 2.0. The User CPU usage on the host keeps climbing, until I reboot the server when it goes back down to almost nothing - and starts to climb again. This is ever since I swapped a Server 2003 VM for a Server 2008 one (upgraded my DC, and migrated to 2008). I can't find any problem with the Windows server though, or any abnormally high CPU usage on the VM itself.
I have been keeping up-to-date on the host, so I've been through about 3 kernel upgrades, numerous recompiles of VMware, and a whole new VMware Server version when the last one was released not too long ago. I just can't figure this one out.
Any suggestions would be very well appreciated, I'm now just looking for things to try!
