Xen 4.3 PCI passthrough possible bug

Xen 4.3 PCI passthrough possible bug

[Mike Neiderhauser]

[-- Attachment #1.1: Type: text/plain, Size: 16621 bytes --]

Hi all,

I am attempting to do a pci passthrough of an Intel ET card (4x1G NIC) to a
HVM.  I have been attempting to resolve this issue on the xen-users list,
but it was advised to post this issue to this list. (Initial Message -
http://lists.xenproject.org/archives/html/xen-users/2014-02/msg00036.html)

The machine I am using as host is a Dell Poweredge server with a Xeon
E31220 with 4GB of ram.

The possible bug is the following:
root@fiat:/var/log/xen# cat qemu-dm-ubuntu-hvm-0.log
char device redirected to /dev/pts/5 (label serial0)
qemu: hardware error: xen: failed to populate ram at 40030000
....

I believe it may be similar to this thread
http://markmail.org/message/3zuiojywempoorxj#query:+page:1+mid:gul34vbe4uyog2d4+state:results


Additional info that may be helpful is below.

Please let me know if you need any additional information.

Thanks in advance for any help provided!
Regards

It appears that it cannot obtain the RAM mapping for this PCI device.


I rebooted the Host.  I ran assigned pci devices to pciback. The output
looks like:

Re: Xen 4.3 PCI passthrough possible bug

[Mike Neiderhauser]

[-- Attachment #1.1: Type: text/plain, Size: 18827 bytes --]

I did not.  I do not have the toolchain installed.  I may have time later

patch the src, compile and install?

Regards

Re: Xen 4.3 PCI passthrough possible bug

[Mike Neiderhauser]

[-- Attachment #1.1: Type: text/plain, Size: 22219 bytes --]

I was able to compile and install xen4.4 RC3 on my host, however I am
getting the error:

root@fiat:~/git/xen# xl list
xc: error: Could not obtain handle on privileged command interface (2 = No
such file or directory): Internal error
libxl: error: libxl.c:92:libxl_ctx_alloc: cannot open libxc handle: No such
file or directory
cannot init xl context

I've google searched for this and an article appears, but is not the same
(as far as I can tell).  Running any xl command generates a similar error.

What can I do to fix this?

Regards

However, I still see the same behavior as before:

Re: Xen 4.3 PCI passthrough possible bug

[Mike Neiderhauser]

[-- Attachment #1.1: Type: text/plain, Size: 35679 bytes --]

I followed this site (
http://wiki.xenproject.org/wiki/Xen_4.4_RC3_test_instructions).
and then followed (http://wiki.xen.org/wiki/Compiling_Xen_From_Source)

git clone -b 4.4.0-rc3 git://xenbits.xen.org/xen.git

Had to take some additional steps here to get all of the libs
# apt-get install build-essential # apt-get install bcc bin86 gawk
bridge-utils iproute libcurl3 libcurl4-openssl-dev bzip2
module-init-tools transfig tgif # apt-get install texinfo
texlive-latex-base texlive-latex-recommended texlive-fonts-extra
texlive-fonts-recommended pciutils-dev mercurial# apt-get install make
gcc libc6-dev zlib1g-dev python python-dev python-twisted
libncurses5-dev patch libvncserver-dev libsdl-dev libjpeg62-dev#
apt-get install iasl libbz2-dev e2fslibs-dev git-core uuid-dev ocaml
ocaml-findlib libx11-dev bison flex xz-utils libyajl-dev# apt-get
install gettext
apt-get install libaio-dev
apt-get install libpixman-1-dev

./configure
make dist
make install

Re: Xen 4.3 PCI passthrough possible bug

[Mike Neiderhauser]

[-- Attachment #1.1: Type: text/plain, Size: 11601 bytes --]

So I went ahead to tested the setup I am trying to achieve using xen.  This
setup basically requires two isolated machines that can be used for network
testing.  On the hvm mentioned above, this testing fails due to something I
cannot wrap my head around.  I believe it is still related to the PCI
passthrough of a device and I believe it is related to the libxl error
mentioned above. Can anyone shed some light on what is going on?  Is it a
driver issue? (Broadcom Corporation NetXtreme II BCM5716 Gigabit Ethernet)

No. Xen pciback does the reset automatically.

Actually we might want to ditch that reporting in libxl, or maybe just
implement a stub function in xen-pciback so that libxl will be happy.

Thanks for the answers on the timeline.

When I start the HVM with th broadcom adapter, I get this message back.
Parsing config from /etc/xen/ubuntu-hvm-1.cfg
libxl: error: libxl_pci.c:990:libxl__device_pci_reset: The kernel doesn't
support reset from sysfs for PCI device 0000:05:00.0
libxl: error: libxl_pci.c:990:libxl__device_pci_reset: The kernel doesn't
support reset from sysfs for PCI device 0000:05:00.1

However, the devices appear in the HVM.  Is this something that I should be
concerned about?

I'm afraid that's about all we can give. :-)  We've locked down
development for 2 months now and are working on finding and fixing
bugs.  If there are no more blocker bugs or other unforeseen delays,
it should be out by the end of February.  But there are necessarily
significant unknowns, so we can't make any promises.

Re: Xen 4.3 PCI passthrough possible bug

[Mike Neiderhauser]

[-- Attachment #1.1: Type: text/plain, Size: 41484 bytes --]

Works like a charm.  I do not have physical access to the computer this
weekend to verify that the cards are isolated, but the HVM starts and
appears to be working well.

When do you think Xen 4.4 will be released.  The article I read mentioned
it will be released in 2014 (hinting towards the end of February).  I also
read 'When it is ready.'

Any timeline would be great.

Thanks again for your help!

Ah, so you are looking for the xen_pt: Fix passthrough of device with ROM. 
which is not in the Xen 4.4-rc3 but in the master. 


One thing you can do is: 


cd xen/tools/qemu-xen-dir 
git fetch upstream 
git checkout origin/master 
[you should see: " HEAD is now at 027c412... configure: Disable libtool if -fPIE does not work with it (bug #1257099)"] 


Go back to main xen directory: 
cd ../../../ 
./configure 
make 
make install 


and you should be using now an newer version of QEMU with the fix.
