Hi Michael,
> Peter, lost the last part of your message ...
Doh: meant to say e.g.
-s 5,virtio-net,tap0,mac=00:0c:29:3f:71:e2
> An alternative would be hashing the vm name with the host name and host MAC address.
Yes, though in that case a VM will end up with a different MAC address
if it's moved to a different host :(
What we'll probably end up doing is to generate a UUID when a VM is
created and hash off that.
later,
Peter.
