[libvirt] KVM/qemu: problems with autostart of vms with non-bridged nets

Hi Daniel,

thanks for looking into this.

I thought about that check too, but decided against it, because

a) currently we always call it with conn=NULL, it only fails if you don't use 
a directly bridged network

b) it currently won't do any harm calling with conn=NULL, creating the vm 
fails later on because it can't find the network device.

But if some code relying on the conn-structure is added later on without 
sanity-checks, this check will make sure no bigger harm is done.

Kind regards,

Gerd
