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

[Alexander Hoßdorf <xen-users@xxxxxxxxxxx>]

Hi,

Have you got persistent mac adress configured for domU?
You have a file called /etc/udev/rules.d/z25-persistent-net.rules in 
debian DomU.
empty it and reboot DomU.

Hope this helps.

Cheers,
Alex
