[Xen-API] External Network dhcp problems

["Markus Rhonheimer" <markus.rhonheimer@xxxxxx>]

Hello,

I have set up an external network on my dom0 xcp server and use an external 
dhcp server/ internet gateway. Creating a PV ubuntu 12.04 VM using the 
automatically created Networkbridges "Network X" works without a problem, as 
the VM is able to retrieve an IP address. When I connect the VM to the external 
network created via Xencenter, it is not able to get an IP address. What am I 
doing wrong?

Here are further informations

XCP version 1.6.07
XCP build number 61365c (the problem occurred with the previous version too)
External Network name: Harlan - Harmony - Netzwerk
XCP dom0 server name: flicka
Xencenter version: 6.1
The external network has the VLAN Tag 1
following: xe pif-list, xe network-list, xe vif-list, xe vm-vif-list, xe vm-list
