Hi David,
Thanks for the quick reply.
I took the rpm from Would you recommend to compile it ?
Here is the dmesg output when i try to start a domU.
device vif1.0 entered promiscuous mode ADDRCONF(NETDEV_UP): vif1.0: link is not ready Ebtables v2.0 registered xenbr1: port 3(vif1.0) entering disabled state device vif1.0 left promiscuous mode
xenbr1: port 3(vif1.0) entering disabled state
Does this make any sense ?
Thanks for the help.
