Well I had given up for some time, but after the inquiry I tried again
yesterday with the released 2.6.38 sources. Not sure what was up with
the -rc versions, but I can finally boot a kernel > 2.6.36. Its pretty
odd since I just copied a config from 2.6.37 which would not boot. Ran
make old config, compiled the kernel and it booted :)
Now I am still getting broken PMU, and missing the stuff above, but I
guess thats moot. Still not able to save or live migrate. This is what I
get in xend.log when I try to save. The save file does seem to grow and
be a decent size. But the vm freezes even when using xm save -c. I was
also unable to restore the vm after destroying the frozen one I saved.
Here is what I get in xend.log. Aside from the error with the evtchn
port, looks like it did save the vm and even restored after I destroyed
it. Not sure if the first failure (second line below) is whats causing
the problem. Or its something relating to using a nfsroot.
