如何使用Python检查虚拟机是否正在运行

import paramiko

client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect('虚拟机IP地址', username='用户名', password='密码')

stdin, stdout, stderr = client.exec_command('systemctl is-active 虚拟机服务名称')
output = stdout.read().decode().strip()

if output == 'active':
    print('虚拟机正在运行')
else:
    print('虚拟机未运行')

import paramiko

def check_vm_status(vm_ip, username, password, service_name):
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(vm_ip, username=username, password=password)
    
    stdin, stdout, stderr = client.exec_command('systemctl is-active ' + service_name)
    output = stdout.read().decode().strip()
    
    if output == 'active':
        print('虚拟机正在运行')
    else:
        print('虚拟机未运行')

check_vm_status('虚拟机IP地址', '用户名', '密码', '虚拟机服务名称')
