qemu-dm-XP.log looks fine. Per  "xm dmesg" log, unmap[ing and mapping 
00:02.0 and 00:02.1 are no problem. But why are there many unmap and map 
(d1 -> d5)? did you create guest 5 times? Could you describe the crash 
you encountered?  BTW, the "xm dmesg" log looks not complete,  it should 
include following logs when you create hvm guest:
(XEN) HVM1: HVM Loader
(XEN) HVM1: Detected Xen v4.0.0-rc3-pre
(XEN) HVM1: CPU speed is 2533 MHz
...

and pls add "iommu=verbose" in grub to get more VT-d info.

Weidong
