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

The loopback and all the network interfaces are startet with rc.inet1 with the config from rc.inet1.conf, both in /etc/rc.d/. In the conf file is only the configuration of the ethernet interfaces. Maybe i write the ifconfig command in the rc.local, and the loopback will also start at the boot time. Not nice, but it´s work...
