通过qemu-agent 可以在宿主机通过命令在虚拟机内执行命名

qemu-agent-command 命令是异步的，执行后命令会返回一个pid，然后通过这个pid轮询的去查询执行的输出结果

如果是正常的结果通过 result.out-data输出，如果是异常通过return.err-data 输出

VMID=f9097a59-973f-ebcf-caf4-f7e1e518c379
QGQIA=$(virsh qemu-agent-command ${VMID} '{"execute": "guest-exec", "arguments": {"path": "/bin/sh",  "capture-output": true, "arg": ["-c", "ps  aux"]}}' | jq .return.pid)
virsh qemu-agent-command ${VMID} '{"execute": "guest-exec-status", "arguments": {"pid": '${QGQIA}'}}'| jq -r '.return."out-data"' | base64 -d
