如何在mininet的每个xterm窗口中自动运行脚本？

from mininet.topo import Topo
from mininet.net import Mininet
from mininet.node import Controller, RemoteController
from mininet.cli import CLI
from mininet.log import setLogLevel

class MyTopo(Topo):
    def build(self):
        # 创建拓扑

if __name__ == '__main__':
    setLogLevel('info')
    topo = MyTopo()
    net = Mininet(topo=topo, controller=RemoteController)
    
    # 启动拓扑
    net.start()
    
    # 在每个xterm窗口中运行脚本
    for host in net.hosts:
        host.cmd('xterm -hold -e python auto_script.py &')
    
    # 进入命令行界面
    CLI(net)
    
    # 停止拓扑
    net.stop()
