How are CPU's allocated in ESXi
Posted on 2008-09-29
I have a Dual Xebn Quad Core HP DL360 G5
I am running VMware ESXi
If I install a 32bit Windows Server 2003 guest and assign it 1 CPU how is this CPU mapped to the cores in the hardware ?
Is it just as it says - a virtual CPU - that really then gets processed by all 8 cores ?
Or is it assigned (or can it be) to one core only?
Furthermore, If I install only 32 bit guests - am I 'wasting' the power of the hardware?
Would I get better performance from a 64bit Windows Server 2003 guest than a 32bit guest ?
