xen discuss - Jun 2009 - xen pciback opensolaris

Hello all,

I''ve got a new box running Xen with Debian Linux (Lenny) running in  
the dom0. Then I have OpenSolaris 2008.11 running in the domU. (For  
the record, I''ve done an ''pkg image-update'' to
2009.06 as well. I
think.) I purchased an Intel 82572EI Gigabit Ethernet controller with  
the expectation of passing it directly to OpenSolaris. Which I can''t  
seem to do. :-(

I have successfully hidden the PCI card with the following added to  
the module options in Grub:

	/boot/vmlinuz-2.6.26-2-xen-amd64 root=/dev/hdb1 ro console=tty0  
pciback.permissive pciback.hide=(01:00.0)

I''ve even added the device to my Xen domU config like so:

	pci = [''01:00.0'']

I can see the device added to the domU when running ''xm list
--long'',
but when I run ''prtconf -pv'' in OpenSolaris there are no
indications
the PCI card exists.

Am I running the wrong command in OpenSolaris to verify the card is  
attached? Is the PCI passthrough simply not supported from Xen to the  
OpenSolaris kernel? What gives?

Any help is appreciated.

Cheers,
Jason

Hi Jason,

Is your OpenSolaris domU a para or fully virtualized guest? I don''t
know whether OpenSolaris PV guest supports a pass-through device.

For fully virtualized guest, please run "scanpci -v" to verify the
existence of the passthrough device.

Thanks,
Allen
