So it seems the problem is IDE/PATA disk/controller is not detected at all with 
the pv_ops dom0 kernel:

xen_allocate_pirq: returning irq 30 for gsi 18
xen_set_ioapic_routing: irq 30 gsi 18 vector 160 ioapic 0 pin 18 triggering 0 
polarity 1
ata_piix 0000:00:1f.1: PCI INT A -> GSI 18 (level, low) -> IRQ 30

xen: PCI device 0000:00:1f.1 pin 1 -> irq 30
xen: disable pci device 0000:00:1f.1
ata_piix: probe of 0000:00:1f.1 failed with error -38
