I had this problem when I forgot to have 'CONFIG_BRIDGE' enabled in my
.config, and also CONFIG_TAP (but I think that was only used during
guest startup) but I don't think that is your problem. It could be related to
this:

"init: eucalyptus-network (eth0) main process (1156) killed by TERM signal"

which might have mangled the eth0? Why is it being killed?

Don't worry about that. These are used to setup the GSI and there is a
second code path that does that.

Interesting. My AMD prototype board shows the same data (or sometimes
even higher number)- completly bogus.

That is b/c the Xen console (all prefixed with XEN) shouldn't by default
be in the Linux domain, unless requested.

or unless you use console_to_ring at which point all of the output
should be synced together. Except that you have '1' at the end instead
of 'g'.
