From: xiajidong <xiajidong@xxxxxxxxxxxxxxxxxxxx>
The optional cpu attribute current can be used to specify whether
fewer than the maximum number of virtual CPUs should be enabled.
when run "virsh setvcpus vm --count <current> --live", it can
display cpu hotpluggable information when run "virsh dumpxml vm
| grep vcpu". so we can know the value of enabled and hotpluggable
attributes of the current vcpus.
