Hi all,
I am
trying to add vcpupin in the guest xml file. I am working with
openstack and the code I have is python bound. I investigated
through the code and found that the elemets in xml file are set in
get_guest_config function. Now the thing is I am not able to set
vcpupin element. I mean I tried guest.cputune_vcpupin but it's not
working.
Hi Peeyush
In libvirt
python -binding . You can find the following functions for pining
vcpus.
class virDomain:
.....
def pinVcpu(self, vcpu,
cpumap):
"""Dynamically
change the real CPUs which can be allocated to a virtual CPU. This
function requires privileged access to the hypervisor.
"""
ret =
libvirtmod.virDomainPinVcpu(self._o, vcpu,
cpumap)
if ret == -1:
raise libvirtError ('virDomainPinVcpu() failed',
dom=self)
return
ret
def pinVcpuFlags(self, vcpu, cpumap,
flags):
"""Dynamically
change the real CPUs which can be allocated to a virtual CPU. This
function requires privileged access to the hypervisor.
"""
ret =
libvirtmod.virDomainPinVcpuFlags(self._o, vcpu, cpumap,
flags)
if ret == -1: raise
libvirtError ('virDomainPinVcpuFlags() failed',
dom=self)
return
ret
.......
Help
me out, please!
Thanks.
