KVM x86_64 with SR-IOV..?

KVM x86_64 with SR-IOV..?

[Nicholas A. Bellinger]

Greetings KVM folks,

I wondering if any information exists for doing SR-IOV on the new VT-d
capable chipsets with KVM..?  From what I understand the patches for
doing this with KVM are floating around, but I have been unable to find
any user-level docs for actually making it all go against a upstream
v2.6.30-rc3 code..

So far I have been doing IOV testing with Xen 3.3 and 3.4.0-pre, and I
am really hoping to be able to jump to KVM for single-function and and
then multi-function SR-IOV.  I know that the VM migration stuff for IOV
in Xen is up and running,  and I assume it is being worked in for KVM
instance migration as well..?  This part is less important (at least for
me :-) than getting a stable SR-IOV setup running under the KVM
hypervisor..  Does anyone have any pointers for this..?

Any comments or suggestions are appreciated!

Hi Nicholas

The patches are not floating around now. As you know, SR-IOV for Linux have
been in 2.6.30, so then you can use upstream KVM and qemu-kvm(or recent
released kvm-85) with 2.6.30-rc3 as host kernel. And some time ago, there are
several SRIOV related patches for qemu-kvm, and now they all have been checked
in.

And for KVM, the extra document is not necessary, for you can simple assign a
VF to guest like any other devices. And how to create VF is specific for each
device driver. So just create a VF then assign it to KVM guest is fine.

Greetings Sheng,

So, I have been trying the latest kvm-85 release on a v2.6.30-rc3
checkout from linux-2.6.git on a CentOS 5u3 x86_64 install on Intel
IOH-5520 based dual socket Nehalem board.  I have enabled DMAR and
Interrupt Remapping my KVM host using v2.6.30-rc3 and from what I can
tell, the KVM_CAP_* defines from libkvm are enabled with building kvm-85
after './configure --kerneldir=/usr/src/linux-2.6.git' and the PCI
passthrough code is being enabled in kvm-85/qemu/hw/device-assignment.c
AFAICT..

>From there, I use the freshly installed qemu-x86_64-system binary to
start a Debian 5 x86_64 HVM (that previously had been moving network
packets under Xen for PCIe passthrough). I see the MSI-X interrupt
remapping working on the KVM host for the passed -pcidevice, and the
MMIO mappings from the qemu build that I also saw while using
Xen/qemu-dm built with PCI passthrough are there as well..

But while the KVM guest is booting, I see the following exception(s)
from qemu-x86_64-system for one of the VFs for a multi-function PCIe device:

BUG: kvm_destroy_phys_mem: invalid parameters (slot=-1)

I try with one of the on-board e1000e ports (02:00.0) and I see the same
exception along with some MSI-X exceptions from qemu-x86_64-system in
KVM guest.. However, I am still able to see the e1000e and the other
vxge multi-function device with lspci, but I am unable to dhcp or ping
with the e1000e and VF from multi-function device fails to register the
MSI-X interrupt in the guest..

Soooo, I enabled the debugging code in kvm-85/qemu/hw/device-assignment.c
and see the PAGE aligned MMIO memory for the passed PCIe device is being
released during the BUG exceptions above..  Is there something else I should
be looking at..?  I have pci-stub enabled, and I unbind 02:00.0
from /sys/bus/pci/drivers/e1000e/unbind successfully (just like with Xen
and pciback), but I am unable to do the 'echo -n 02:00.0
> /sys/bus/pci/drivers/pci-stub/bind' (it returns write error, no such
device, with no dmesg output) on the KVM host running v2.6.30-rc3.  Is
this supposed to happen on v2.6.30-rc3 with pci-stub..?  I am also using
the the kvm-85 source dist kvm_intel.ko and kvm.ko kernel modules.  Is
there something I am missing when building kvm-85 for SR-IOV passthrough..?

Also FYI, I am having to use pci=resource_alignment=
because the BIOS does not PAGE_SIZE align the MMIO BARs for my multi-function
devices..

Also, I tried with disabling the DMAR with the Intel IOMMU passthrough
from this patch:

https://lists.linux-foundation.org/pipermail/iommu/2009-April/001339.html

that did not make it into v2.6.30-rc3.  The patch logic was enabled but
still I saw the same kvm exceptions from qemu-system-x86_64.

Anyways, I am going to give it a shot with the Fedora 11 x86_64 Preview
and see if it works as expected with a IOH-5520 chipset with the AMI
BIOS on a Tyan S7010 with Xeon 5520s.  Hopefully this is just a kvm-85 build
and/or install issue I am seeing on my CentOS 5u3 install (that has a Xen PCIe
passthrough setup on it as well) with v2.6.30-rc3.  I will try on a fresh install
on a distro with the new KVM logic and see what happens.

:-)

Thanks for your comments!

This one is mostly harmless.

Did you see the interrupt in the guest and host side? I think you can try on-
board e1000e for MSI-X first. And please ensure correlated driver have been 
loaded correctly. And what do you mean by "some MSI-X exceptions"? Better with 
the log.

That part of memory should be released for trap MMIO for MSI-X table.

Maybe you need "echo 0000:02:00.0 > /sys/bus/pci/drivers/pci-stub/bind"?

I think the first thing is to confirm that device assignment work in your 
environment, using on-board card. You can also refer to 
http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM

And you can post debug_device_assignment=1 log and qemu log and the tail of 
dmesg as well.

Thanks!

Ok, I am restarting the e1000e test with a fresh Fedora 11 install and
KVM host kernel 2.6.29.1-111.fc11.x86_64.   After unbinding and
attaching the e1000e single-function device at 02:00.0 to pci-stub with:

   echo "8086 10d3" > /sys/bus/pci/drivers/pci-stub/new_id
   echo 0000:02:00.0 > /sys/bus/pci/devices/0000:02:00.0/driver/unbind
   echo 0000:02:00.0 > /sys/bus/pci/drivers/pci-stub/bind 

I see the following the KVM host kernel ring buffer:

   e1000e 0000:02:00.0: PCI INT A disabled
   pci-stub 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
   pci-stub 0000:02:00.0: irq 58 for MSI/MSI-X

Ok, with the Fedora 11 installed qemu-kemu, I see the expected
kvm_destroy_phys_mem() statements:

#kvm-host qemu-kvm -m 2048 -smp 8 -pcidevice host=02:00.0 lenny64guest1-orig.img 
BUG: kvm_destroy_phys_mem: invalid parameters (slot=-1)
BUG: kvm_destroy_phys_mem: invalid parameters (slot=-1)

However I still see the following in the KVM guest kernel ring buffer
running v2.6.30-rc in the HVM guest.

I am going to double check my v2.6.30-rc3 KVM guest kernel build for the
PCI options.  Is there anything special I need to enable other than PCI
express support in the v2.6.30-rc3 guest under the PCI Bus options in
the kernel config..?  DMAR and Interrupt Remapping should be DISABLED in
the guest HVM kernels, right..?

Also just an observation, I noticed that in Xen HVM with SR-IOV
passthrough the PCIe devices appear as 05:00.0 after an 'xm pci-attach'
call.  Is there a reason that SR-IOV with KVM attaches said passthrough
devices under the 00.* PCI bus instead of it's own $NEXT_BUS_ID.00.0
value under the KVM guest.?  Does this have any effects on
functionality..?

Many thanks for your most valuable of time,

Hi Sheng,

Btw, this is what it looks like in KVM HVM guest running v2.6.30-rc3 after plugging
in the port and dhcp occuring..  The KVM HVM does not hard lock (cool :-), and I am
still able to access via the built-in qemu net-device.  Here are my .config options
for the v2.6.30-rc3 KVM guest running on top of 2.6.26.6-79.fc9.x86_64 Fedora 11
Preview KVM Host.  I am missing something in the v2.6.30-rc3 KVM guest config for
accessing an e1000e port SR-IOV below..?

Many thanks for your most valuable of time,

Whoops, that should have been 2.6.29.1-111.fc11.x86_64 for Fedora 11
Preview KVM Host kernel btw..

Ok, I also noticed the following output in /proc/interrupts on KVM host
with dual Intel E5520 processors (16 CPUs)

[root@barret ~]# cat /proc/interrupts | grep MSI

eth0 is the other e1000e port at 03:00.0 that is in use on the KVM host,
and it looks like the other e1000e port at 02:00.0 has been setup to
kvm_assigned_msi_device on irq 58.

I also noticed the following after starting a KVM guest in host's ring
buffer (not sure if this has anything to do with -pcidevice usage)

>From there, I keep seeing the same MSI-X and MSI registration failures
from the e1000e driver from within the v2.6.30-rc3 KVM guest from above,
and will the exception will trigger the same netdev watchdog TX timeout
are observed.

I will try building a v2.6.29.y stable kernel in the guest HVM and see
if that makes any difference.  So far, it seems like it is a KVM guest
kernel issue with my v2.6.20-rc3 builds.  Is there anything else I
should be looking at on the FC11 KVM host to verify that everything from
the host side is working at expected..? 

Please let me know if you need any more information.

Hi Nicholas

I think something need to be clarify:
1. For SRIOV, you need 2.6.30 as host kernel... But it's better to know if 
normal device assignment work in your environment at first.
2. The Fedora's userspace is even more old... You'd better try qemu-kvm 
upstream, which is more convenient for us to track the problem(and kvm-85 is 
also ok). And as you see above, your QEmu don't support MSI/MSIX...

So you can:
1. Use latest qemu-kvm or kvm-85's QEmu. As well as latest KVM.
2. Your host kernel is Fedora 11 Preview, that should be fine with device 
assignment at first(and let's solve it first, SRIOV the next step).
3. Your KVM version seems like kvm-85, you may provide some dmesg on host 
side(I think you didn't use the KVM come along with kernel).
4. Your guest kernel is somehow new, maybe you can change it to something like 
2.6.29.x which is more stable(but it may not matter). And you are right, no 
special setup needed for guest kernel (just suppose it's run in a no-VT 
capability machine).

And you can post your _host_ dmesg, as well as the output of debug for 
kvm-85/qemu/hw/device-assignment.c when you don't get response from dhcp.

Unhandled MSR doesn't matter - and I thought they have already been discard 
long ago?

I saw the interrupt of host assigned device seems fine, you can also check if 
guest have interrupt for that device.

Thanks.

Ok, I am now updated on in the FC 11 Host with kvm-85 kernel modules and
am using the built qemu-system-x86_64 from the kvm-85 source package:

loaded kvm module (kvm-85)

Ok, yeah I will stick with the v2.6.29 fc11 kernel on the KVM host for
the momemt to get e1000e working.  But I will start building a
v2.6.30-rc3 kernel again for my fc11 host kernel as I do need SR-IOV at
some point... :-)

Ok, now within the KVM guest running v2.6.29.2, I see the following:

And the folllowing from /proc/interrupts inside of the KVM guest:

 24:        117          0          0          0          0          0          0          0          0          0   PCI-MSI-edge      eth1-rx-0

ethtool eth1 reports that Link is detected, but I am still unable to get
a dhcp to work.

However, I do not see the netdev watchdog TX timeouts this time with
kvm-85, but still no ping to eth1 from KVM guest..

I will retest with the v2.6.20-rc3 guest and see if MSI-X is able to
successfully come-up and get dhcp.

Attached is the dmesg from the 2.6.29.1-111.fc11.x86_64-iov-dmesg KVM

It's a little strange that I checked all the log you posted, but can't find 
anything suspicious...(Except you got a MCE log in your dmesg, but I don't 
think it would relate to this).

You also already have interrupts in the guest for eth1-rx-0 and eth1, so at 
least part of interrupts can be delivered to the guest. 

You can try to connect the port to another NIC port directly. Set fixed ip for 
each, then ping each other.

You can also try to disable MSI-X capability in QEmu. Just using "#if 
0/#endif" to wrap "#ifdef KVM_CAP_DEVICE_MSIX/#endif" in 
hw/assigned_device_pci_cap_init(). Then the device would use MSI.

If I am lucky enough to find a 82574L card by hand, I would give it a try...

Greetings Sheng,

So I updated my FC11 Host to kernel v2.6.30-rc3 (and enabled ext4 of
course) and rebuilt the kvm-85 source kernel module and
qemu-system-x86_64 and I am now able to get dhcp and IP ops from the
02:00.0 device on my IOH-5520 board with the KVM guest using a v2.6.29.2
kernel!!  Everything is looking good with the v2.6.29.2, but after a
quick reboot back into my v2.6.30-rc3 KVM guest kernel build e1000e it
looks like I am unable to get dhcp.

Rebooting back into KVM Guest kernel v2.6.29.2 brings the pci-stub
assigned e1000e 82574L assigned with dhcp and everything looks
good!  :-)

I will keep poking at the v2.6.30-rc KVM guests (I am going to do a
complete rebuild) and see if it does not start move IP packets as well..

Thanks for all of your help in getting setup!

Re: KVM x86_64 with SR-IOV..?

[Yu Zhao]

Hi,

The VF also works in the host if the VF driver is programed properly.
So it would be easier to develop the VF driver in the host and then
verify the VF driver in the guest.

BTW, I didn't see the SR-IOV is enabled in your dmesg, did you select
the CONFIG_PCI_IOV in the kernel .config?

Thanks,
Yu

Re: KVM x86_64 with SR-IOV..? (device passthrough with LIO-Target v3.0)

Greetings Yu and Sheng,

So the original attachment was for the v2.6.29-fc11 host kernel output,
I ended up jumping to v2.6.30-rc3 (and making sure CONFIG_PCI_IOV was
enabled) for KVM host with kvm-85 and now things are looking quite
stable for me.

So far I have been able to successfully push LIO-Target v3.0 traffic
*inside* a v2.6.29.2 KVM guest via the onboard e1000e (02:00.0) port
from another Linux/iSCSI Initiator machine using a Intel 1 Gb/sec port.
I am running badblocks tests to iSCSI Logical Units for RAMDISK_DR and
FILEIO storage objects (in the KVM Guest), and they are passing
validation and I am seeing ~500 Mb/sec of throughput and very low CPU
usage in the KVM guests.

One issue I did notice while using the pci-stub method of
device-assignment with same e1000 port (02:00.0) was while using an
iSCSI Initiator (Open-iSCSI) on the KVM Host machine and doing sustained
traffic into the LIO-Target KVM Guest on the same local KVM host to max
out traffic between the other onboard e1000e port (03.00.0), I see the
following:

pci-stub 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
assign device: host bdf = 2:0:0
pci-stub 0000:02:00.0: irq 59 for MSI/MSI-X

Attached are the v2.6.30-rc3 KVM host and v2.6.29.2 KVM guest dmesg
output.  When the 'Unbalanced enable for IRQ 59' happens on the KVM
host, I do not see any exceptions in KVM guest (other than the iSCSI
connections drop), but it requires a restart of KVM+qemu-system-x86_64
to get the e1000e port back up.

Other than that loopback scenario, things are looking good quite good
with this combination of kvm-85 kernel+guest so far for me.  I did end
up taking out the two 8x function 2x Path/Function PCIe IOV adapters for
now, as it seemed to have an effect on stability with all of MSI-X
interrupts enabled on the KVM host for 16 virtual adapters.

I will keep testing with e1000e ports and let the list know the
progress.  Thanks for your comments!

Ok I am seeing another issue with the e1000e port on 02:00.0..:

As i start to push multiple badblocks tests RAMDISK_DR iSCSI Logical
units into KVM Guest running LIO v2.6.29.2 from the external Linux/iSCSI
Initiator machine, after about 100 GB of iSCSI traffic, I see the
following exception in KVM host v2.6.30-rc3:

DRHD: handling fault status reg 2
DMAR:[DMA Write] Request device [02:00.0] fault addr 7fc958b010000 
DMAR:[fault reason 04] Access beyond MGAW
pci-stub 0000:02:00.0: irq 59 for MSI/MSI-X
pci-stub 0000:02:00.0: irq 60 for MSI/MSI-X
pci-stub 0000:02:00.0: irq 61 for MSI/MSI-X

I am able to restart the LIO-Target KVM Guest and the Linux/iSCSI
Initiators are able to reconnect..  Wow, very cool..

Not sure if this is a bug in the target_core_mod RAMDISK_DR subsystem
plugin (mapping struct iovec to internally allocated struct page) or
what.  I will have to look at the DMAR code to understand what this
exception means..

Greetings Yu, Sheng and Co,

So I have been making progress this morning..  So far, I have hooked up
a LSI mpt-function PCIe SAS adapter into the KVM guest with a Sandisk
SATA SSD 32 GB drive.  It is using MSI interrupts (not MSI-X) and I am
able to push ~70 MB/sec from a 2nd Linux/iSCSI Initiator machine
(running Open-iSCSI) with the 1500 byte MTUs on e1000e ports from within
the KVM guest. 

The interesting thing is that I am having to use IBLOCK export (using
using submit_bio(), and complete emulation of SCSI control path) for
SATA SSD in order to get I/O running stable  Using the pSCSI export I am
getting immediate exceptions from scsi_execute_async() in the v2.6.29.2
KVM guest..  Using a 2nd SAS disk I am able to use target_core_mod/pSCSI
export and push badblocks and LTP disktest traffic however..

Here is a bit about the the setup looks,

The SATA SSD is available as /dev/sde on the Linux/iSCSI Initiator node,
the 2nd SAS disk was removed from the dmesg below as having multiple
drives on the mpt-function card made it start to hiccup..

Is MSI-X can't be enabled or the device only have MSI capability? Just 
curious...

Didn't see exception in the log below... (And buried with iscsi log I can't 
understand. Looking forward for the help from others...) Any thing notable 
show in the host side? I think the target to get pSCSI work well now?

BTW: Maybe you can try the patch from Marcelo titled "[patch 0/4] use 
smp_send_reschedule in vcpu_kick / assigned dev host intx race fix".

AFAICT MSI-X is not supported on the mpt-fusion SAS device when running
on the KVM host..

Yeah, the log attached was using the SATA SSD with the IBLOCK export
(the one that worked..).  The exception that I was seeing from pSCSI
export from the same SATA SSD from within KVM Guest running v2.6.29.2
involved a non-zero return from
drivers/scsi/scsi_lib.c:scsi_execute_async() for basically all bulk
struct scatterlist I/O (the control path seemed OK however).

Unfortuately, scsi_execute_async() was (it has been removed for v2.6.30)
really bad at returning any useful value and hardcodes a return of
'DRIVER_ERROR << 24' in the error path, so I was unable to determine
anything useful for what was actually causing it to fail during my
initial testing..

I will keep poking at it and see if I can find anything interesting..

Thanks for the pointer, I will have a look.

Many thanks for your most valuable of time,
