Hello, I have a All-in-One OpenStack Victoria. And I want to bind vCPU of openstack instance(guest) to pCPU of host. # virsh edit instance-00000107 origin: ``` ... <vcpu placement='static'>8</vcpu> <cputune> <shares>8192</shares> </cputune> ... ``` after modify: ``` <vcpu placement='static' cpuset='104-111'>8</vcpu> <cputune> <shares>8192</shares> <vcpupin vcpu='0' cpuset='104'/> <vcpupin vcpu='1' cpuset='105'/> <vcpupin vcpu='2' cpuset='106'/> <vcpupin vcpu='3' cpuset='107'/> <vcpupin vcpu='4' cpuset='108'/> <vcpupin vcpu='5' cpuset='109'/> <vcpupin vcpu='6' cpuset='110'/> <vcpupin vcpu='7' cpuset='111'/> <emulatorpin cpuset='104-111'/> </cputune> ``` But If I stop and start instance by openstack command, xml automatically recover. And If I user `virsh shutdown instance-00000107 && virsh start instance-00000107`, instance can't be start(I don't konw if the openstack instance must be started using openstack command). So: 1. Can I modify the xml of openstac instance by 'virsh edit'? 2. If I can't modify the xml, how can I bind vcpu of guest and pcpu of host I would appreciate any kind of guidance or help. HanGuangyu
