which version of xen you used? Did xen crash without iommu=1 when vt-d enabled?
If you can post the panic info, it would be more helpful.
best regards

Subject: [Xen-devel] VT-d Problem with Xen
Dear Xen Developers,
I installed Qubes OS using Xen Hypevisor on my PC which contains an Intel i5 750
Processor.
In BIOS the VT-d support is enabled, but while booting my system xen crashes.
I already tried the boot parameters iommu=pv and iommu=workaround_bios_bug, but
without any improvement.
The message xen shows when crashed is:
Panic on CPU 0
fatal page fault
error code [0000]
Please let me know if you need any further information from me, regarding my
system.
Many thanks,
Steve
