Hello, I am trying to pass my LSI SAS 2008 controller to my PV domu (openindiana) and I can not get it working. I have read that xen does not support the loading of option ROM''s in pv domu''s and that this support is being, or will be, added. http://markmail.org/thread/2njw43iaurmvzlys This post is more than a year old now. I am wondering if there is a way to get my LSI SAS controller working in my pv domu? I am using Debian Squeeze (kernel 3.1.10) dom0 on xe 4.2-unstable (24785) and am using the xl tool stack.

Where should I be enabling DMA access? In the kernel, or elsewhere? I am not a very experienced linux user.

Did you edit menu.lst you need to block PCI device from dom0 and blacklist module for card Sent from my Windows Phone ------------------------------ From: Sandi Romih Sent: 4/30/2012 4:14 PM To: jacek burghardt Cc: xen-users@lists.xensource.com Subject: RE: [Xen-users] LSI SAS 2008 controller in a pv domu> > lf you do lspci do you see the device in domu?

I have added a blacklist file for mptsas in /etc/modprob.d/ and updated initramfs, but it does not help. I even recompiled the kernel WITHOUT mptsas driver support..... it still loads mptsas at boot... Do I need to disable the LSI controller in the BIOS to get it properly blackisted?
