I had this problem when I forgot to have 'CONFIG_BRIDGE' enabled in my

guest startup) but I don't think that is your problem. It could be related to

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

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

I'm going to investigate this but I suspect it dies because eth0 isn't there. The euca network works fine after I restart networking.

However, there are still errors in the pv_ops dom0 console
output so I'm attaching the output so someone could see if they are
serious or if there are workarounds to improve things.  I'm seeing
things like 'unable to locate IOAPIC for xxx', call trace from
Don't worry about that. These are used to setup the GSI and there is a
second code path that does that.
Ok. But then why bother writing these scary messages that just confuse things?

enlighten.c, 'd0 domain attempted wrmsr', 'Detected 1226681.732 MHz
processor.'(a 1.2 TeraHz processor??? - the processor is actually a 3.1
GHz processor), 'No compatible ACPI _PSS objects found.'.
Interesting. My AMD prototype board shows the same data (or sometimes
even higher number)- completly bogus.
I'm wondering if this bothers delay loop timings, etc. ???

Plus, why do I see slightly different outputs on the consoles?  Some
errors only show on one of the consoles but not the other.
That is b/c the Xen console (all prefixed with XEN) shouldn't by default
be in the Linux domain, unless requested.
.. snip..
(XEN) Command line: dummy=dummy dom0_mem=1024M  vga=text-80x50  loglvl=all 
guest_loglvl=all sync_console console_to_rin1

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'.
The '1' is an artifact due to the command line actually being truncated. It's actually the last character on the line.

Yeah, no kidding!  :-)

Thanks for the help and looking at this.
