Thanks. Did you use earlyprintk=xen on the kernel command line as well as the loglvl=all stuff on the hypervisor command line? Now I think of it can you also collect a similar log with the dom0_mem workaround in place, for comparisons sake. > > Assuming that shows that the domain 0 kernel did actually get a chance > > to run and crash I'll take a look at what else needs to be clamped to > > have it just work. > > From what I can see in the log, the dom0 kernel doesn't seem to get > started. It does rather look that way. If you press Ctrl-A three times on the hypervisor serial console then you might be able to inject some hypervisor debug keys. Such as 'q' which should dump a dump of interesting state about dom0. '0' and 'd' might also print something of interest. Press 'h' for a list of available keys.
