you mean you assign MegaRAID SAS controller with VT-d to your guest?
You'd better provide more info, such as
serial output, so people can be easy to help you.

Subject: megaraid sas driver
failing in Xen-3.4 unstable version
On Xen-3.4 (unstable version), I have created CentOS
HVM guest & WS2K8 HVM guest and dedicated MegaRAID SAS controller but I am
not able to see the disk which is connected to MegaRAID SAS controller when I
do fdisk –l (vtd support is enabled in
Xen).
Looks like the pci device(MegaRAID SAS controller)
is getting dedicated successfully as I can see the device in the list of pci
devices shown by lspci(on CentOS HVM).
00:06.0 RAID bus controller: LSI Logic / Symbios
Logic MegaRAID SAS
However the driver is not getting attached properly
and fails with the following error
=======================================================================================
“dmesg” of HVM CentOS
megasas: Failed to init firmware
ACPI: PCI interrupt for device 0000:00:06.0 disabled

On WS2K8 HVM, I am able to see MegaRAID SAS
controller under “Storage Controllers” on WS2K8 HVM and the status of device is
