Subject: 2.6.27, kvm-kmod, and PCI device assignment
Date: Mon, 12 Sep 2011 11:56:46 -0600 [thread overview]
Message-ID: <4E6E47DE.6080602@genband.com> (raw)
Hi,
I've been away a bit but I'm now coming back to this issue.
Is it expected that the kvm-kmod modules will allow PCI device
assignment (aka VT-d) with older kernels? If so, then is there an
expectation for how far back it will be supported? I haven't seen a
clear statement of this anywhere, and I think David was interested in
this as well.
Looking at the instructions at
"http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM",
step 4 is to unbind the device from the host using the "pci_stub"
functionality. That code was only added to mainline for 2.6.29-rc1, so
it seems like extra work will be needed for 2.6.28 and earlier.
Thanks,
Chris
