[Xen-devel] XenD lost its uniqueness check for names & UUIDs

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

I'm doing some testing against today's xen-unstable.hg and it appears that
XenD has lost its uniqueness checks for names & UUIDs. eg

# xm create XenGuest2
Using config file "/etc/xen/XenGuest2".
Started domain XenGuest2
# xm create XenGuest2
Using config file "/etc/xen/XenGuest2".
Started domain XenGuest2
# xm create XenGuest2
Using config file "/etc/xen/XenGuest2".
Started domain XenGuest2
# xm list
Name                                      ID   Mem VCPUs      State   Time(s)
Domain-0                                   0   698     2     r-----   2915.3
XenGuest1                                 24   394     4     -b----     32.0
XenGuest2                                 32   300     1     r-----      0.3
XenGuest2                                 30   300     1     ------      3.2
XenGuest2                                 31   300     1     --p---      0.0

# xm list --long | grep uuid | sort | uniq -c
      1     (uuid 00000000-0000-0000-0000-000000000000)
      1     (uuid c7a5fdb0-cdaf-9455-926a-d65c16db1809)
      3     (uuid c7a5fdb2-cdaf-9455-926a-d65c16db1809)

So I now have 3 active guests with same name and same UUID :-(

Now it should always be possible to run 'xm new' to define a persistent 
config file for a transient domain, but, attempts to run 'xm create' 
should be rejected if there is an existing domain.

Dan.
