I haven't seen you post the non-pvops versus pvops grub stanzas for
comparison, but assuming the Xen line in each stanza is identical, it would
be really odd that one gets you Xen boot output and the other doesn't. Are
you setting up Xen to print to serial line in exactly the same way in both
cases?

The only thing I could think of, if the GRUB setup is okay, is that Xen is
messing up with the particular size of pvops kernel+initrd you pass to it.
I.e., a bug where Xen fails really early, before setting up serial line
even. That would make you very unlucky since I can't remember when we last
had such an early bug, but it is possible.
