Re: [Qemu-discuss] newbie question: how to connect to a running guest with qemu monitor

[Han Han]

virsh qemu-monitor-command is the answer.
You can use it by following:
For qmp command:
# virsh qemu-monitor-command  $VM_NAME $QMP_COMMAND
For hmp commmand:
# virsh qemu-monitor-command --hmp $VM_NAME $HMP_COMMAND
