View Full Version : [ubuntu] Performance using KVM

( Sorry if wrong place to ask )
I was wondering how performance is affected when using KVM and the number of cores/processors on the machine. All machines will be running versions of Ubuntu ( 10.04 - 64 bit desktop and server ).
I currently have 2 processors with 2 cores each - would I be better off trying to get the dual quad cores working when using multiple KVM guests. The quad cores are lower speed - but having twice the number of cores might help.
The problem being the upgrade requires a bit of motherboard surgery and I'm not sure if the possible risk is worth the benefits.
