Hi,
I want to change the cpu pinning for inactive domain on RHEL-5.1.
So, I just add the xenXMDomainPinVcpu to xm_internal.c.
We will be allowed to change "cpus" parameter in configuration file
with "vcpupin" command by this patch, like "setmem" or "setvcpus".
There is 2 things to note:
- This is an effective feature for inactive domain with
Xen3.0.3 (less than 3 of xendConfigVersion).
- On the above environment, the number which specified as
<vcpu> is ignored, because the virtual CPUs is not present
when domain is shut off. So, when executing "vcpupin" command
with this option
# virsh vcpupin Guest 0 1
"0"(vcpu) is ignored and "1"(cpulist) is set to configuration file
as "cpus".
# cat /etc/xen/Guest | grep cpus
cpus = "1"
