[Xen-users] controlling /proc/cpuinfo
I need to control what the machine shows and /proc/cpuinfo. For example, my
virtual machine shows 8 CPU's, but I think that these look like independent
CPU's to the apps. I need to change this to look like they are two cpu's and
4 cores per cpu. I need this because my software licensing requires this
scheme and also because it is actually true, I have four physical CPU's and
4 cores each.
