Actually, pv-ops dom0 boot successfully. I remotely access my machine via
serial console. Normally after dom0 boot, it display "login:" line. But serial
console stops at ioapic_guest_write messages when boot pv_ops, I thought it's
hung.
But I found xend still cannot be started. I got the following messages when I
start it:
[root@vt-randy ~]# xend start
