<div> </div><div>But when I login the website, I find that every VM has no ip or network interface(only loopback interface), so I create a port for a VM, but after I reboot the VM( or even reboot physical node ), the VM vid does not appear.</div>
<div> </div><div>So how can I add the original interface to the existing VM, please? It is really a big problem for me, some data is still in those VMs.</div><div> </div><div>Thansk in advanced.</div><span class="HOEnZb"><font color="#888888"><div>
