The attached patch adds the following options to the xenguest-install.py
script:
-U, --genuuid Generate a random UUID and exit
-M, --genmac Generate a random MAC address and exit
-C CONFOUT, --genconf=CONFOUT
Generate a template guest config file
Is this something that people think might be useful? If so I'll raise
an RFE in bugzilla.
Take care,
Gawain
