I've always run vCenter as a VM itself with 1 vCPU and never had any issues (related to loads, haha).

...then again I only have 5 hosts and less than 250 VMs.

Hello.

kb 1009080 and the ESX and vCenter Server Installation Guide both state 2 CPUs is the requirement. The Installation Guide also states that "The vCenter Server system must meet specific requirements."

It really seems to come down to whether or not you want a supported configuration. If you call in for support, you might possibly be asked to up your system to meet the requirements before you are helped. I don't personally know, but I could see this happening. It could be an obstacle, or a minor annoyance to obtaining timely support.

Duncan's site has a great entry about sizing vCenter. Using Duncan's recommendations and depending on the size of your environment, it could be a moot point.

Good Luck!

I have 21 esx hosts and 100 linked clones -- I haven't experienced any issues running vCenter with 1 Vcpu. One thing to remember is to deploy the database on a seperate server.
