It seems that libvirt is not cpu hotplug aware.
Please refer to the following problem.
1. At first, we have 2 cpus.
# cat /cgroup/cpuset/cpuset.cpus
0-1
# cat /cgroup/cpuset/libvirt/qemu/cpuset.cpus
0-1
2. And we have a vm1 with following configuration.
cputune
vcpupin vcpu='0'

Hi,
this approach requires that libvirtd keeps running through the entire
lifecycle of a guest. That is something that cannot be safely assumed
and therefore hotplug events can be missed.
That means that libvirt must synchronize the hypervisors
