That should be console=com1 so you have a typo either in this message or
in your tests.
sync_console gives an extra message but that's all I could see.
Is
console=hvc0 correct for a KVM guest, or is that only going to work for
xen-on-xen ? I tried console=ttyS0 as well but it didn't make a difference
It is hvc0 to send it to xen and thus onto the console you specified
above. You can get some early debug messages of the kernel with
earlyprintk=xen and "log_lvl=all guest_loglvl=all" are recommended at
http://wiki.xenproject.org/wiki/Debugging_Xen for the xen hypervisor line.
