When nova through KVM assigns VCPU's or "cores" they show up as physical CPU's inside of Windows rather than a single CPU with X cores. Is there a way to change that behavior to support assigning more than 4C to a WIndows 2008 R2 Standard server ?

The Physical host is running Dual Intel E5-2660 2.2Ghz 8c processors and nova seems to launch the windows servers with a core2duo -smp 8,sockets=8,cores=1, threads=1

I think There is an way to fix this problem set up the windows image with hw_cpu_topology metadata.

Do you get a fix for this problem?

The Metadata is:

Number of CPU sockets
Number of cores per socket
Number of threads per core

Flavor Metadata
