Hi Hyun Woo,

My all hosts(gcloud01~03) have a virsh command 



[root at gcloud03 ~]# which virsh
/usr/bin/virsh
[root at gcloud03 ~]# virsh -c qemu:///system nodeinfo
CPU 모델:          x86_64
CPU:                 6
CPU 주파수:       2660 MHz
CPU 소켓:          1
소켓당 코어:    6
코어당 스레드: 1
NUMA cell:           1
메모리 용량:    24597092 KiB

[root at gcloud03 ~]#



Thanks
