You should remove that unsupported 'tty' option.

So Xen hypervisor is fine, but it's the dom0 kernel that crashes.

Please add 'console=hvc0 earlyprintk=xen' options for your Linux _kernel_ (not for Xen),
assuming it's pv_ops dom0 kernel..

That should give you more output to figure out the reason for the crash.

What's your dom0 kernel version? Custom built?
