[Xen-users] Constructor code in MAC address does matter ?

I observed a strange networking behaviour of my Debian virtual host in function of the MAC address I use. It seems that when I use an existing constructor code, networking works without any problem, but is impossible in the other case...
Ex. :
- vif = [ 'mac=aa:00:00:00:00:55, bridge=xen-br0' ] -> no problem
- vif = [ 'mac=df:00:00:00:00:55, bridge=xen-br0' ] -> the bridge does not transmit my packets apparently. No DHCP possible, and when I used a static address I can't ping the bridge from the guest... Is it normal ? Is it really related to constructor code ? I use a Xen 2.0.6 on a Debian Sarge host with kernels
