I am using Ubuntu 12.04.4 64 bit .

After installing virt-manager, I found my scenario would be to user bridge networking, so I managed to let my machines works with bridge interface br0.

From that time I lost the network-manager. It shows that device is not managed.

Can I bring my network interface to work in parallel with virt-manager?

There is no way to do that.

As they cannot be 2 GODs for this life (If you believe in GOD :P)

Only One Netwrok Manager is There:

Either network-manager or virt-manager

I can accomplish this by defining bridge in network-manager and disable bridge in virt-manager. That's the solution.

I share it for the benefit of All
