Xen crash on dom0 shutdown
There is a BUG_ON() at xen/arch/x86/physdev.c:169 which appears to
be dependent upon guest behavior (should close event channel before
un-mapping pirq), rather than on internal hypervisor state. In 2.6.18,
this likely goes unnoticed because pci_device_shutdown() only calls all
the driver shutdown routines. In newer kernels, however, it also calls
pci_msi_shutdown() and pci_msix_shutdown(), which

[VTD][patch 0/5] HVM device assignment using vt-d
The following 5 patches are re-submissions of the vt-d patch.
This set of patches has been tested against cs# 15080 and is
now much more mature and tested against more environments than
the original patch. Specifically, we have successfully tested
the patch with following environements:
- 32/64-bit Linux HVM guest
- 32-bit Windows XP/Vista (64-bit should work but did not test)
-
