We could set blank ip address

IP setting->Configure->Mode (static), then press "OK".

And libvirt will throw an error not very helpful:
Error creating interface: 'Could not define interface:
XML error: could not get interface XML description:
XML invalid - Element protocol failed to validate attributes.

This patch will forbid setting an empty ip address.
