[Xen-users] I/O Vitualization disbaled problem

[Dipak Dudhabhate <dipak.dudhabhate@xxxxxxxxx>]

Hello,

I am trying xen 3.4.1 with kenel-xen 2.6.31-rc6, i am not able to create virtual machine by using PCI passtrough to assign one of my PCI device 
to guest OS. But it thorows error like "VT-d is not  enabled". I am using command "xm create Fedora9.conf"

Fedora9.conf is my config file.

Following is the output of "xm dmesg"

I have enabled virtualization in BIOS, 

I am able to use PCI passthrough using KVM virtualization.

I am wondering why with same H/W i am not able to use same functionality?

Please let me know again about MSI, is that too needed to be enabled.


thanks
