Xen users - Mar 2011 - [XCP] No network after upgrade from 0.5 to 1.0

Hi guys,

I upgraded my home server to check out XCP 1.0 but i have a big problem.
After the upgrade my network just died.

I see the card, it''s listed as xenbr0 but there is no network
acces/connection going over it. A ping to or from the server results in
nothing.

When i check out the configure managment interface settings i see the NIC,
and it states connected. But there is no way to get a IP adres true DHCP.
Also when i enter a valid static configuration, i can''t seem to ping my
laptop. When i downgrade back to 0.5 it works fine.

It''s a: RTL8111/8168B PCI express Gigabit Ethernet controller.

Any idea''s/pointers?

Thanks!
Peter

It seems others are having this problem on XenServer 5.6 FP1 (which
XCP was originally derived from).

Hope that helps.
