[Xen-users] help with xen networking on debian
hi everyone,
i've managed to install xen on sid and sarge, using this useful howto:
http://www.debian-administration.org/articles/320
i've got my virtual machine to startup, but networking doesnt really work!
my setup is as follows:
i have a router/gateway 192.168.1.1
my base host (moya) is 192.168.1.4
my virtual server (test18) is 192.168.1.18
from the virtual server, i can ping the base host and from the base
host i can ping the server. however, when i try and ping the gateway,
or anywhere else from the vitual server i get:
"From 192.168.1.18 icmp_seq=1 Destination Host Unreachable"
i also tried installing on sid and got exactly the same problem. i'm
not trying to do any fancy networking, just to get it working "out of
the box" :)
here is some info from moya (base host):
