[Xen-users] Make 2, 3 & 4 V-CPU HVMs appear as a one socket multicore CPU
I have read the examples like the one below but still do not understand how I can make 2, 3 and 4 VCPU system appear as a single socket multi core CPU in the HVM. Does anyone know what I would have to set the CPUID to in order to achieve this? Example: +# Example for amd, expose a 5-core processor : +# cpuid = [''1:ebx=xxxxxxxx00000001xxxxxxxxxxxxxxxx, +# edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx'', +# ''0x80000008:ecx=xxxxxxxxxxxxxxxx0000xxxx00001010''] +# - CPUID.1[EBX] : (Thread * Cores ) per processors +# - CPUID.1[EDX][HT] : Enable HT +# - CPUID.0x80000008[ECX] : Number of vcpus * 2 +#vcpus=5 Thanks, Rob The SAQ Group Registered Office: 18 Chapel Street, Petersfield, Hampshire.
