[Xen-devel] 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" pciback 0000:02:0e.0: seizing device PCI: Enabling device 0000:02:0e.0 (0190 -> 0192) ACPI: PCI Interrupt 0000:02:0e.0[A] -> GSI 66 (level, low) -> IRQ 25 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) Description: Windows was able to successfully install device driver software, but the driver software encountered a problem when it tried to run. The problem code is 10.
