RE: [Xen-devel] VT-d Problem with Xen

["Zhang, Yang Z" <yang.z.zhang@xxxxxxxxx>]

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
