Package: xen-tools
Version: 3.9-4
Severity: minor
When xen-create-image makes a new xen domain and no mac address for the
virtual NIC of the domain is provided, it tries to create one at random.
These are the lines doing the job:
foreach my $key (qw/ hostname ip dhcp dist /)
{
$hash .= $CONFIG{ $key } if ( $CONFIG{ $key } );
}
Since $CONFIG{'dhcp'} is an array reference, the hashed string will look
like this:
"mydomainARRAY(0x604d80)lenny"
hostname and debian distribution are hashed but the ip isn't - just the ip's
position in main memory (which is usually always the same).
Possible solution: Replace these three lines by
$hash=$CONFIG{'hostname'};
if ( $CONFIG{'ip'} ) { $hash .= join('.',@{$CONFIG{'ip'}}); }
if ( $CONFIG{'dhcp'} ) { $hash .= $CONFIG{'dhcp'}; }
$hash .= $CONFIG{'dist'};
