Hi All.
I inherited an OpenSUSE Version 11.4 Xen host machine here at work.
Without too much trouble I finished upgrading it to Version 12.1.
The old setup was running using the Xen "xm" toolstack and works like
you'd expect. The new setup works ok if I use the "xm" stack as well.
I learned that we should move to the "xl" toolstack. I'm trying to do
that now and having some problems with networking, but only with the xl
approach.
I've been running up to date Xen for awhile.
rpm -qa | grep -i xen

I already setup the networking on the Host to use OpenSUSE
configuration.

I get no other output here (why not?) on the console for about 30
seconds. Then just,

I can login to the guest at the console and the Guest's networking looks
like it's recognized OK.

But when I try to ping anywhere off the Guest I get HostUnreachable
errors.

etc etc
It feels like I'm pretty close to getting this working. Am I still
missing some part of the configuration changes needed for using the xl
toolstack?

Erin
