Reading pv_ops wiki page I noticed this:

"If the domain crashes very early, before any output appears on the console,
then booting with: "earlyprintk=xen" should provide some useful information.
If you are running a debug build of Xen hypervisor (set "debug = y" in
Config.mk in the Xen source tree), then you should get crash dumps on the
Xen console. You can view those with "xm dmesg"."

So I guess earlyprintk=xen is only useful if you're running debug build of
Xen hypervisor.. ?
