今天安裝完kvm，滿是幸福的裝了個xp，重啟後出現了一個錯誤

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

詳情：

Details:

Error starting domain: Requested operation is not valid: network ?default‘ is not active

Traceback (most recent call last):
File ?/usr/share/virt-manager/virtManager/asyncjob.py“, line 91, in cb_wrapper
callback(asyncjob, *args, **kwargs)
File ?/usr/share/virt-manager/virtManager/asyncjob.py“, line 127, in tmpcb

if ret == -1: raise libvirtError (?virDomainCreate() failed‘, dom=self)
libvirtError: Requested operation is not valid: network ?default‘ is not active

解決辦法：

sudo virsh net-start default
sudo virsh net-autostart default

原因需要查看命令

啟動虛擬機命令： virt-manager
sudo virsh net-list  --all

python@kali:~$ sudo virsh net-list --all
 Name                 State      Autostart     Persistent
----------------------------------------------------------
 default              active     no            yes　　　　// 看是no，所以導致了這個錯誤

同時要註意一個問題，就是在虛擬機配置

虛擬網絡接口

　　網絡源：  虛擬網絡‘default‘: NAT

　　設備型號： rtl8139
