Hi List,

I face troubles while just using the xen-enabled kernel in Kubuntu Hardy
(8.04). I just don't have no network at all. If I run ifconfig I see the
peth0 and lo is up. ifconfig -a shows all the virtual interfaces and one
called "tempbr0" or so. But all of them are down. I can't tell exactly as I
have to reboot and use another kernel to get network access back...

peth0 has got my address and is set up as default gateway. But no
ping and telnet works. It just doesn't forward my packets to the router as it

Any ideas?

Try running /etc/xen/scripts/network-bridge start manually.

You may need to clean out the tmpbr0 manually.
to do that use:
brctl show
ifconfig tmpbr0 down
brctl delif <any interface on that bridge>
brctl delbr tmpbr0

Albert's suggest is a good one since you will
run into the domU network problem at some
point if you don't use those fixed kernels
