Physical resource vs Virtual resource
Posted on 2011-09-16
When you add or allocated addition CPU or RAM from the virtual guest server, is that equavalent to adding extra physical CPU or RAM in the physical environment.
What I noticed for instance particularly in VMWare, even though I have only dual core CPU on the vmware host server, I can still create multiple vmware guest servers and allocate two virtual CPUs to several of my virtual guest servers.
If that is the case, having only dual core CPU (physical) on the vmware host server, how is it possible that you can allocate more virtual CPUs to several vmware guest servers when you only have 2 physical CPU?
I thought you can only allocate CPU or RAM based from your available physical resource?
Appreciate your detail explanation?
