Requested operation is not valid: network 'default' is not active

错误信息

Debian系统通过KVM部署虚拟机，运行 virt-install 指定 --network network=default 的时候会出现下面的错误：

ERROR    Requested operation is not valid: network 'default' is not active

问题解决

1. 确定virth环境中有default网络，如下：

[email protected]:/home/th# virsh net-list --all
 Name                 State      Autostart     Persistent
----------------------------------------------------------
 default              inactive   no            yes

2. start当前default网络
   virsh net-start default

[email protected]:/home/th# virsh net-start default
Network default started
