[PATCH] Fix buildsystem to detect udev > version 124

[Marc - A. Dahlhaus [ Administration | Westermann GmbH ]]

[-- Attachment #1: Type: text/plain, Size: 229 bytes --]

udev removed the udevinfo symlink from versions higher than 123 and xens
build-system could not detect if udev is in place and has the required
version. Attached patch fixes this.

I am building xen-3.4-test tree on Ubuntu 9.04. Booting process
reports error like:

....
udev: starting version 141
udev: deprecated sysfs layout; update the kernel or disable
CONFIG_SYSFS_DEPRECATED;....
....

Is that true that your patch is to fix this problem?

I tried, but the problem still persists. Any idea?

Thanks,
J

[-- Attachment #1.1: Type: text/plain, Size: 1755 bytes --]

Marc's patches work for me on Xen 3.4.1 Dom0 (2.6.30-rc6-tip) has been built on top Ubuntu 9.04 Server with python 2.6. Config.mk tuned to setup default path for python
 /usr/local/lib/python2.6/dist-packages.
Hotplug scripts not working message gets gone. Now i can load F11 & Jaunty PV DomUs
and access Internet from DomUs. However, one problem still persist:-

If just once by some reason DomU failed to shut down cleanly. Hotplug locking doesn't
get clean up automatically and i had reboot Xen Host.

Marc's patch does nothing to Config.mk, so you modified that Config.mk
yourself? Could you send that patch to list?

I am struggling to make 3.4 work on Ubuntu 9.04 - the error is always
about "not finding /dev/apgart", even I compiled agpart as builtin. I
think udev is the culprit, but still struggling here ...

You could downgrade your udev or upgrade your kernel (which i would
prefer here) but i doubt that you really need the functionality that
udev only gets out of newer sysfs layouts.

By the way, the warning doesn't hurt at this point as your system runs
fine...

Just keep in mind that 2.6.18 kernel is stoneaged and that a newer
kernel would get around this warning.


have fun,

Marc

[-- Attachment #1.1: Type: text/plain, Size: 1636 bytes --]

I just used CS Changeset 19594 to set in Config.mk
PYTHON = python
PYTHON_PREFIX_ARG =
Otherwise , xend wouldn't start.
Setting above place xen packages into /usr/local/lib/python2.6/dist-packages
and creates Xen Host on top Jaunty Server seems healthy, but affected by udev issue.
When I applied Marc's patch udev issue appears to be resolved.

Re: [PATCH] Fix buildsystem to detect udev > version 124

[Boris Derzhavets]

[-- Attachment #1.1: Type: text/plain, Size: 2683 bytes --]

I've created and loaded  f11 and Ubuntu Server Jaunty PV DomU at Xen 3.4.1-rc4 Dom0  with 2.6.30-rc6-tip kernel on top Ubuntu 9.04 (python 2.6) . Then performed about 1 hr internet sessions at DomUs. Marc's udev patch seems to be working fine.
Udev issue was affecting straightforward Xen build on Ubuntu 9.04 for about 2 months
or so.

Where this patch is supposed to go either xen-unstable.hg or xen-3.4-testing.hg (both) ?
Systems affected Ubuntu 9.04 (now) , F12 (pretty soon).

It would solve the problem with 2.6.30-rc6(3)-tip pvops kernel or
2.6.29.4 xen-ified per Suse (2.6.27 XCI as well)

Could go into 3.4 and unstable IMO.

On 3.3 there is no tools/hotplug/Linux/Makefile so it must be altered
there to use tools/examples/Makefile for the first chunk and should work
fine there.

By some reasons i have to run  on regular basis run ./xen-hotplug-cleanup
on two Xen 3.4.1 on top of Ubuntu 9.04 Servers patched systems to re-enable ability start DomUs without hotplug scripts failure.

Re: [PATCH] Fix buildsystem to detect udev > version 124

[Marc - A. Dahlhaus]

Hello Boris,

as the problem you are describing is unrelated to the patch (which 
changes the detection of udev during buildtime only),
can you please change the subject line to something more appropriate and 
give some additional details about the problem?

Re: [PATCH] Fix buildsystem to detect udev > version 124

[Dulloor]

I see that these patches made it to xen-unstable, but I still see the
"Hotplug Scripts not working ..." error on my jaunty dom0 machine.

I am trying to run a simple para-VM. xend starts fine (had to build
tools with PYTHON_PREFIX_ARG set to ""). And, I tried
xen-hotplug-cleanup too, but still getting the error.

Any ideas ?
