I am trying to figure out how to set the number of CPUs per socket in my VMs.  My install of Win2003Server Enterprise should support at least 16 CPUs, but it sees only 8.  I was told this is because by default, Xen 3 gives the guest OS vcpus at 1 per socket and W2k3E supports "8 sockets."  How can I set Xen to give more than one CPU per socket?  I have 32 CPUs available (8 quad-core opterons). 

I looked in the config file and it is claiming that my VM should have 16 CPUs, but it only shows 8.  I have verified that as a host OS, W2k3Ent supports 16 CPUs on a 8-dual-core-opteron system.
