[Xen-devel] 82576 VF passthrough
I am trying to setup 82576 VF passthrough to pv domU non Vt-d machine . My dom0 is http://hg.vergenet.net/xen/linux-2.6.18-xen-igb/ kernel on FC11 and 3.4.1 Xen. My domU is also http://hg.vergenet.net/xen/linux-2.6.18-xen-igb/ kernel on Ubuntu junty.
Passthrough of PF device (igb driver) is successful in my setup. I could see the PF BDF on domU, and the igb driver gets loaded on domU.
But, when I do passthrough of VF device, lspci output on DomU doesn't show the VF device.(CONFIG_XEN_PCIDEV_FRONTEND=y)
The steps I follow on Dom0:
#modprobe igb max_vfs=1
#echo -n VF-BDF > /sys/bus/pci/drivers/pciback/new_slot
#echo -n VF-BDF > /sys/bus/pci/drivers/pciback/bind
On domU config file has pci = [' VF-BDF'] .
The domU starts without any errors.
#xm pci-list domU-ID
shows the VF BDF
Am i missing some thing of VF Passthrough? Please give me pointers to find/debug the issue.
