Im running 64bit centos 5.6 and using virt-manager.
On one of my guest OS''s, Windows 7, The max Physical CPUs is 2, you can
have
unlimited CPU Cores however. (like my machine i use for work has 1, 4 core
processor).
The issue im having is xen only allows you to set the vcpu arguemnet in your
xen config file. How can i set it so that 1 CPU has several Cores just as
windows would recognize this machine if i were installing directly to the
hardware vs via a VM.
Ive searched for 2 days staright trying to address this issue, very little
progress, here are a few links of info i found but did not help.
Does anyone know where a XEN support forum is? all i get is the citrix xen
support forums.
here is the best info i have found on this, but i dont know how to change
this for my CPU to work, when i enter this in my xen config it essentially
ignores it and just takes the value of vcpu
> # Expose to the guest multi-core cpu instead of multiple processors
> # Example for intel, expose a 8-core processor :
> #cpuid=[''1:edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx,
> # ebx=xxxxxxxx00010000xxxxxxxxxxxxxxxx'',
> # ''4,0:eax=001111xxxxxxxxxxxxxxxxxxxxxxxxxx'']
> # - CPUID.1[EDX][HT] : Enable HT
> # - CPUID.1[EBX] : Number of vcpus * 2
> # - CPUID.4,0[EAX] : Number of vcpus * 2 - 1
> #vcpus=8
thanks!
