[et-mgmt-tools] [PATCH]Check the starting domain's uuid

[Tatsuro Enokura]

Hi

The virt-install command has a problem that the information of
the existent domain is overwritten by virt-install command
specifing the domain's uuid.
Futhermore, the existent domain's set-up file is overwritten
on the xen-3.0.4.

I make a patch checking the starting domain's uuid on Guest.py.
