Hi,

I've fiddled around with xen running on Ubuntu, Debian and now PCLinuxOS.

I am running XEN on a very basic network setup: eth0 is a standard
ethernet link, and the loopback device lo:

eth0 Link encap:Ethernet HWaddr 00:17:08:40:DF:D3
inet addr:192.168.101.1 Bcast:192.168.101.255 Mask:255.255.255.0
inet6 addr: fe80::217:8ff:fe40:dfd3/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:50164 errors:0 dropped:0 overruns:0 frame:0
TX packets:32533 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:48693133 (46.4 MiB) TX bytes:4102657 (3.9 MiB)

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:42045 errors:0 dropped:0 overruns:0 frame:0
TX packets:42045 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:116910974 (111.4 MiB) TX bytes:116910974 (111.4 MiB)

Initially, networking did not work. It was referring to an adapter with
index 5 ("veth5 does not exist") which already seemed strange to me (why
5, it should use 0?).
I had to increase the number of loopback devices to make it work. But is
still strange.

Is there something I can do about this? I would like things to behave as
expected. There has to be some reason why XEN uses xenbr5 instead of
xenbr0? I tried to find a config file where I can specify the bridge to
create, but I can't find it.


Best regards
Sam
