Just remove the UUID from the config file and start the VM; no need to destroy it.

Well, I had to shut it down before it could use a different UUID. That's what I meant. I removed the UUID from all config files now, thanks for the tip!

I use uuidgen to generate a random uuid, and then use this python script to generate a random mac address.

I think this was on a help page somewhere that I stumbled across.

#! /usr/bin/python # macgen.py script generates a MAC address for Xen guests # import random mac = [ 0x00, 0x16, 0x3e, random.randint(0x00, 0x7f), random.randint(0x00, 0xff), random.randint(0x00, 0xff) ] print ':'.join(map(lambda x: "%02x" % x, mac))
