I don't want xend.log. I want xen log (xm dmesg or captured by serial port). 
And pls also post qemu log (/var/log/xen/dm-qemu-xxx.log).

Sorry about that, attached are the output from xm dmesg and the qemu-dm-XP.log 

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.
