RE: [Xen-devel] FW: megaraid sas driver failing in Xen-3.4 unstable version

["Han, Weidong" <weidong.han@xxxxxxxxx>]

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.

 

Regards,

Weidong

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

 

 

“/var/log/messages”

 ACPI: PCI interrupt for device 0000:02:0e.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

This device cannot start.(Code 10)
