[Xen-users] Re: unstable network problem

[Tim Durack <tdurack@xxxxxxxxx>]

Okay, fixed it by using a bridged setup.

This doesn't work:

Dom0 vif1.0 <-> guest eth0

This does work:

Dom0 vif0.0 bridged with Dom0 vif1.0. Ip address applied to Dom0 veth0
and guest eth0.

Would be much simpler in my mind if the first scenario worked as expected...
