The Perfect Xen 3.1.0 Setup For Debian Etch (i386)

[ko0nz]

hi,

i'm testing xen 3.1 in a debian testing several time:
- firstly, my installing stopped before installing xen-tools
and i can't have access to the network, neither my gw.
i can ping my own adress but i can't ping else.

- lastly, my installation stopped before installing xen-tools and
after reboot of the xen kernel in a new station, i can ping my network x.x.2.x, my gw x.x.2.1
but i can't ping x.x.10.x
my network is a vlan : x.x.2.x and x.x.10.x are different network.

is there something wrong about the network with xen 3.1 and debian ?

thanks in adavance for your help.

What exactly did you change in your network settings? What's in /etc/network/interfaces, what's the output of

ifconfig

?

hmm...i can't tried it because i uninstalled xen 3.1
