[Xen-users] Problem with loopback device in xenU

["Jochen" <gerribaldi@xxxxxxxx>]

Hi!

I´m a newbie in xen, but get 2 guest machines to work ;). In generall
everything is working, and it´s a great thing to have different servers on
one hardware.
Unfortunally i have a problem in all my xen guest machines. The loopback
device don´t start automaticly on boot time. When i type ifconfig lo i get
the messages:

lo        Link encap:Local Loopback
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

With ifconfig add 127.0.0.1 the loopback device is starting to work.
Normally should it be started on boot timte, or? The linux is a Slackware
10.1, also in the guest machines. The network config in generall is working,
also the loopback device is compiled in the kernel (not as modul). Anybody
any idea about this?

Thanks 
Jochen
