This is about CPU affinity. You may look at CPU pinning with 'vcpupin'

in the manual of virsh. It is possible to enable vCPU pinning in libvirt
guest XML.
Don't know if libvirt supports applying CPU affinity at guest runtime
but you could do it with usual tools (taskset, htop, etc).
I don't know how to change the affinity use tasket for the vms in the libvirt,
my goal it to get the downtime from core 0 to core 2
