Hi folks, the RHEL5 Virtualization guide has some nice info on this:
http://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Virtualization-e...
1) As Olivier mentioned, uuidgen is a built-in app that will generate a valid, unique, uuid.
2) this script (gakked from the above webpage) will generate a mac address:
#! /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))
Enjoy!

For the mac I tend to randomly change one of the last 6 characters. It is easier for the uuid as you can use the uuidgen command to generate a new one.
