[Xen-devel] PCI Passthrough to HVM on xen-unstable

I am working on S5000VSA Intel Server Board with the following cpu spec.

XEN-PEER-RHEL5 $ cat /proc/cpuinfo

power management:

Is my box vt-d capable? If the answer is yes proceed ahead to the details. If
the answer is no, how can a novice user like me identify whether or not his box
is vt-d capable.

I am attaching below snapshots of dump that I think are relevant. You could see
the following:
	a) XEN specific dom0 kernel config.
	b) menu.lst entry
	c) Guest VM (which is a Sles10 HVM) config file.
	d) dmesg | grep pciback which says that hidden device indeed exists.

When I start the HVM I get the following error:

XEN-PEER-RHEL5 $ xm create sles10disk.cfg
Using config file "./sles10disk.cfg".
Error: Fail to assign device(4:0.0): maybe VT-d is not enabled, or the device is
not exist, or it has already been assigned to other domain


The following thing surprises me:

	a) If my device - (4:0.0) is indeed hidden in Dom0 but *not assigned* to the
HVM, realtek card shows up at (4:0.0) in HVM''s lspci as below. Note
that my dom0
kernel config has CONFIG_XEN_PCIDEV_BACKEND_PASS=y which I believe is
*non-default*.

RE: [Xen-devel] PCI Passthrough to HVM on xen-unstable

Pls check your BIOS to see whether it''s VT-d capable, and enable it
first if you want to use it. Seems your configures are correct, pls
check your BIOS.

I don''t see an option for "Intel VT for Directed I/O" when
"Intel Virtualization
Technology" is enabled. My understanding is that VT-d is a motherboard
feature
and not a processor feature.

I have done some limited research looking around. I am confused whether I can
get VT-d to work with just a BIOS upgrade or I would be required to upgrade my
box altogther. If you have some info off the top of your head to clarify things
for me, I would appreciate it.

RE: [Xen-devel] PCI Passthrough to HVM on xen-unstable

Yes, VT-d is located at North bridge, not a processor feature. On BIOS,
it should be under Chipset -> North Bridge settings.

RE: [Xen-devel] PCI Passthrough to HVM on xen-unstable

Usually, vt-d option is under the advanced chipset setting / northbridge
setting. So please check whether your BIOS has such an entry.

And also, for latest c/s, if vt-d is not enabled, there will be a warning for it
when you create a HVM guest with vt-d assignment.

I don''t see an option for "Intel VT for Directed I/O" when
"Intel Virtualization
Technology" is enabled. My understanding is that VT-d is a motherboard
feature
and not a processor feature.

I have done some limited research looking around. I am confused whether I can
get VT-d to work with just a BIOS upgrade or I would be required to upgrade my
box altogther. If you have some info off the top of your head to clarify things
for me, I would appreciate it.

Northbridge chipset on my machine is this: Intel Corporation 5000V Chipset
Memory Controller Hub (rev b1).

I need to have an Intel Q35 Express Chipset to get VT-d enabled.

At this point I need to shelve the idea of testing PCI Passthrough on HVM.
Thanks a lot for helping with my questions.
