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

vcpu-pin cause dom0 kernel panic
I use xen 4.0(dom0 is suse11.sp1,2.6.32 x86_64) on
Dell R710 with PERC H700 RAID adapter.
--Intel(R) Xeon(R) CPU E5620 @ 2.40GHz
--8 CPU cores.
--Memory 64G
--RAID5 4.5T
When I dedicated (pin) a CPU core only for dom0 use.
(I specify "dom0_max_vcpus=1 dom0_vcpus_pin" options for Xen)
I got dom0 kernel panic error(pin-1-5.30.bmp)
When I pin 2 core to dom0, the dom0 system can boot up,
