Summary: VT-d NIC does not work in HVM guest Product: Xen Version: unstable Platform: All OS/Version: All Status: NEW Severity: blocker Priority: P1 Component: Hypervisor AssignedTo: xen-...@lists.xensource.com ReportedBy: haic...@intel.com

Environment:

------------ Service OS (ia32/ia32e/IA64): ia32 ia32e Guest OS (ia32/ia32e/IA64): ia32 ia32e Change Set: 18139 Hardware: Stoakley

Bug detailed description:

-------------------------- We create one HVM guest with one PCI or PCIe NIC assigned, the assigned NIC does not work, guest can not get IP address.

Reproduce steps:

---------------- 1) prepare one OS image(linux or Windows) 2) create HVM guest with one NIC assigned

Current result:

----------------

Expected result:

----------------

Basic root-causing log:
