Re: [Xen-users] Cloning VM from Xen

[Benjamin Knoth <knoth@xxxxxxxxxxx>]

 Hi Simon,
good news network is running.
After i delete the old network device on
/etc/udev/rules.d/30-persistent-net.rules and /etc/sysconfig/network/
and add the new network device in this directory manually, the network
is now running.

Thanx a lot for your help.

best regards
Benjamin
