I have successfully booted xen on Fedora 14 x86_64 with iommu=force on
the kernel line, I can unbind a pci device and rebind to pci-stub and
see it with xm pci-list-assignable-devices. That's cool. Now I have an
Intel 82576 dual-port ET Adapter that supports SR-IOV and started
configuring everything to enable it's virtual functions:
added pci_pt_e820_access=on to the module line that contains the
created igb.conf under /etc/modprobe.d with options igb max_vfs=7
added blacklist igbvf to /etc/modprobe.d/blacklist.conf
I was under the impression that I should see some kind of message about
MMCONFIG in xm dmesg, but there isn't anything. I do a xm dmesg | grep
-i pci and it finds nothing with MMCONFIG. I guess my next question is
what do I do next? How do I troubleshoot further? Below is the VT-d
messages from xm dmesg:
(XEN) Intel VT-d Snoop Control supported.
(XEN) Intel VT-d DMA Passthrough not supported.
(XEN) Intel VT-d Queued Invalidation supported.
(XEN) Intel VT-d Interrupt Remapping not supported.
Does MMCONFIG have something to do with the fact the Interrupt
Remapping not supported message is displayed?
