RE: [Xen-devel] Disable PCI passthrough FLR as an option?

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

Actually we have such a xend option in the xen-unstable tree:
The option is at the end of /etc/xen/xend-config.sxp: 
(pci-passthrough-strict-check yes). Uncomment it and change it to no and do a 
"xend restart".

 
Thanks,

Subject: [Xen-devel] Disable PCI passthrough FLR as an option?

Hello,

People seem to want to pci-passthrough just a single port from dual-port
NICs.

It doesn't seem to work anymore, and Xen complains like this:

http://lists.xensource.com/archives/html/xen-users/2009-12/msg00267.html

"Error: pci: improper device assignment specified: pci: 0000:04:00.0
must be co-assigned to the same guest with 0000:04:00.1, but it is not
owned by pciback."

With "disable FLR" patch it works OK:
http://lists.xensource.com/archives/html/xen-users/2009-12/msg00338.html

That user is using the first port of the NIC in dom0, and passing
through the second port to domU.

Can we have an option in Xen guest cfgfile to disable flr?
