Re: [Xen-devel] PCI Passthrough of SAS controller not working

["Hao, Xudong" <xudong.hao@xxxxxxxxx>]

In your guest lspci log file, I do see the attached SAS device is owned by mpt2sas driver in your guest log.

 

We did simple testing with a SAS controller assignment to RHEL6.2 guest on Xen unstable 25164, both passthrough and pci-attach/detach works well.

 

Sharing the log to you, and can you update your Xen to latest and try?

 

 

Thanks,

Subject: [Xen-devel] PCI Passthrough of SAS controller not working

 

Hello.

 

I tried to setup PCI Passthrough of a SAS controller into a PVHVM domU. The device was present in the domU but its modules wouldn't load.

 

The first related thing was the following message in the guest BIOS just before grub starts:

MPT BIOS Fault 09h encountered at adapter PCI(00h,05h,00h).

 

I'm attaching the xm dmesg and dmesg from both the host and a guest as well as lspci -v.
