Re: [Xen-users] Debian domU interface naming strangeness

[Stephan Seitz <s.seitz@xxxxxxxxxxxx>]

Additionally, add a fixed mac adress to your vif line in your domU config, like

vif = [ 'mac=nn:nn:nn:nn:nn:nn,brigde=xxxxx' ]

otherwise domU's udev will start counting again on every boot (say, mac address 
change)
