[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) ?

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 ?

"Hotplug Scripts not working ..." error on jaunty

[Marc - A. Dahlhaus]

Hello,

The patches only fixed the build-time and installation-time detection of 
  udev to work with version above of 124.

Have no jaunty based box around here to get some impressions of what 
goes wrong in this setup.

Could you check what udev version it has and if /etc/hotplug and/or 
/etc/udev contains xen related stuff?

As udev is in charge of hotplug events on jaunty a
"udevadm monitor" might get you some further details on what events are 
generated.

Check what files get installed in /etc/udev and /etc/hotplug during 
installation. If you find anything xen related in /etc/hotplug remove it 
and check if that fixes your problem.

It would be interesting to know how you install xen...

Re: "Hotplug Scripts not working ..." error on jaunty

[Dulloor]

- udev version is 141 (udevadm info -V)

- There is only a /etc/udev directory. It had two files : xend.rules
and xen-backend.rules. Removing them didn't help.

- I use pvops kernel. And, I use - make install-xen and make
install-tools PYTHON_PREFIX_ARG=""

- Following is the output from "udevadm monitor" :

It  was written on June 26, 2009 and was connected with some particular 9.04 instance.
Since then i did several Xen Host installs via official 3.4.1  tarball and via xen-unstable.hg  but, every time the most recent JF's pvops kernel had been built to
support Dom0. Problem with hot-plug scripts was gone far away.
My question :-
What kernel is supporting your Dom0 ?

Boris.
P.S. Seems to me , that was kernel related problem in June.

- udev version is 141 (udevadm info -V)

- There is only a /etc/udev directory. It had two files : xend.rules
and xen-backend.rules. Removing them didn't help.

- I use pvops kernel. And, I use - make install-xen and make
install-tools PYTHON_PREFIX_ARG=""

- Following is the output from "udevadm monitor" :

Please, tell how you setup Xen 3.4.1 or Xen  Unstable on 9.04 server ?

Boris.

P.S. Working sample:-

It  was written on June 26, 2009 and was connected with some particular 9.04 instance.
Since then i did several Xen Host installs via official 3.4.1  tarball and via xen-unstable.hg  but, every time the most recent JF's pvops kernel had been built to

support Dom0. Problem with hot-plug scripts was gone far away.
My question :-
What kernel is supporting your Dom0 ?

Boris.
P.S. Seems to me , that was kernel related problem in June.

- udev version is 141 (udevadm info -V)

- There is only a /etc/udev directory. It had two files : xend.rules
and xen-backend.rules. Removing them didn't help.


- I use pvops kernel. And, I use - make install-xen and make
install-tools PYTHON_PREFIX_ARG=""

Re: Re: "Hotplug Scripts not working ..." error on jaunty

[Dulloor]

[-- Attachment #1.1: Type: text/plain, Size: 11426 bytes --]

I use xen-unstable (at the tip again). I have been following your blog.
Thinking of it, the only difference is I use 9.04-Desktop-amd64 for my base
installation. I will try 9.04-Server (not sure if it will help though). Btw,
these VM images were working fine with 8.04 installation.

1. I believe it will help.
2. Bruce's  Edge feed would be also very much wanted.

I use xen-unstable (at the tip again). I have been following your blog. Thinking of it, the only difference is I use 9.04-Desktop-amd64 for my base installation. I will try 9.04-Server (not sure if it will help though). Btw, these VM images were working fine with 8.04 installation.

It  was written on June 26, 2009 and was connected with some particular 9.04 instance.
Since then i did several Xen Host installs via official 3.4.1  tarball and via xen-unstable.hg  but, every time the most recent JF's pvops kernel had been built to


support Dom0. Problem with hot-plug scripts was gone far away.
My question :-
What kernel is supporting your Dom0 ?

Boris.
P.S. Seems to me , that was kernel related problem in June.

Re: Re: "Hotplug Scripts not working ..." error on jaunty

[Dulloor]

[-- Attachment #1.1: Type: text/plain, Size: 13252 bytes --]

Boris,

The "hotplug" error is gone with 9.04 server. The VMs boot fine (atleast per
logs and xm list).

I am not able to access VM via console(hvc0) though. I have tried everything
out there in your blogs, but the console just freezes at this same point :
"
[    0.010000] Initializing cgroup subsys memory
[    0.010000] Initializing cgroup subsys freezer
"
Any clues on how to go about debugging this ?

I use the default network-nat configuration for VMs(with addresses from
10.0.0.1/24). That doesn't work either. Is that expected too ?
I am sure the bridge configuration should work though (will try tomorrow).

Re: Re: "Hotplug Scripts not working ..." error on jaunty

[Boris Derzhavets]

[-- Attachment #1.1: Type: text/plain, Size: 12326 bytes --]

You have to take care of hvc0 like tty1 entry under /etc/event.d on:
1. Ubuntu's <= 9.04 pv guest
# cd /etc/event.d
# cp tty1 hvc0
and edit hvc0 file correspondently
2. /etc/inittab on CentOS 5.3 DomU
should have entry
hvc0:23:respawn:...:hvc0
like for tty1,tty2 and etc

and so on,  console=hvc0 at /boot/vmlinuz-xen  module's line requires
activating hvc0 via guest's specific location, view for instance :-

http://bderzhavets.wordpress.com/2009/05/21/install-ubuntu-jaunty-pv-hvm-domus-at-xen-3-4-dom0-kernel-2-6-30-rc6-tip/

or just tell exactly which one (linux) PV DomU is causing you trouble with serial console.

Boris.
P.S. F11, U 9.04 Server , OpenSuse 11.1(2)  PV DomUs may loaded  via vfb as well,but U 9.10 Server (beta) requires serial console

Boris, 

The "hotplug" error is gone with 9.04 server. The VMs boot fine (atleast per logs and xm list).

I am not able to access VM via console(hvc0) though. I have tried everything out there in your blogs, but the console just freezes at this same point :

"
[    0.010000] Initializing cgroup subsys memory
[    0.010000] Initializing cgroup subsys freezer
"
Any clues on how to go about debugging this ?

I use the default network-nat configuration for VMs(with addresses from 10.0.0.1/24). That doesn't work either. Is that expected too ? 

I am sure the bridge configuration should work though (will try tomorrow).

1. I believe it will help.
2. Bruce's  Edge feed would be also very much wanted.

I use xen-unstable (at the tip again). I have been following your blog. Thinking of it, the only difference is I use 9.04-Desktop-amd64 for my base installation. I
 will try 9.04-Server (not sure if it will help though). Btw, these VM images were working fine with 8.04 installation.

It  was written on June 26, 2009 and was connected with some particular 9.04 instance.
Since then i did several Xen Host installs via official 3.4.1  tarball and via xen-unstable.hg  but, every time the most recent JF's pvops kernel had been built to



support Dom0. Problem with hot-plug scripts was gone far away.
My question :-
What kernel is supporting your Dom0 ?

Boris.
P.S. Seems to me , that was kernel related problem in June.

- udev version is 141 (udevadm info -V)

- There is only a /etc/udev directory. It had two files : xend.rules

Re: Re: "Hotplug Scripts not working ..." error on jaunty

[-- Attachment #1.1: Type: text/plain, Size: 13121 bytes --]

I used to work with NAT for DomUs only on Fedoras 12,11,10,8 (libvirtd & dnmask).
Due to absence libvirt ->xen driver on Ubuntu's Servers 9.04,8.10 i always configured
xen bridge via /etc/xen/xend-config.sxp. It works fine.

You have to take care of hvc0 like tty1 entry under /etc/event.d on:
1. Ubuntu's <= 9.04 pv guest
# cd /etc/event.d
# cp tty1 hvc0
and edit hvc0 file correspondently
2. /etc/inittab on CentOS 5.3 DomU
should have entry
hvc0:23:respawn:...:hvc0
like for tty1,tty2 and etc

and so on,  console=hvc0 at /boot/vmlinuz-xen  module's line requires
activating hvc0 via guest's specific location, view for instance :-

http://bderzhavets.wordpress.com/2009/05/21/install-ubuntu-jaunty-pv-hvm-domus-at-xen-3-4-dom0-kernel-2-6-30-rc6-tip/

or just tell exactly which one (linux) PV DomU is causing you trouble with serial console.

Boris.
P.S. F11, U 9.04 Server , OpenSuse 11.1(2)  PV DomUs may loaded  via vfb as well,but U 9.10 Server (beta) requires serial console

Boris, 

The "hotplug" error is gone with 9.04 server. The VMs boot fine (atleast per logs and xm list).

I am not able to access VM via console(hvc0) though. I have tried everything out there in your blogs, but the console just freezes at this same point :

"
[    0.010000] Initializing cgroup subsys memory
[    0.010000] Initializing cgroup subsys freezer
"
Any clues on how to go about debugging this ?

I use the default network-nat configuration for VMs(with addresses from 10.0.0.1/24). That doesn't work either. Is that expected too ? 

I am sure the bridge configuration should work though (will try tomorrow).

1. I believe it will help.
2. Bruce's  Edge feed would be also very much wanted.

Boris.

I use xen-unstable (at the tip again). I have been following your blog. Thinking of it, the only difference is I use 9.04-Desktop-amd64 for my base installation. I
 will try 9.04-Server (not sure if it will help though). Btw, these VM images were working fine with 8.04 installation.

Please, tell how you setup Xen 3.4.1 or Xen  Unstable on 9.04 server ?

It  was written on June 26, 2009 and was connected with some particular 9.04 instance.
Since then i did several Xen Host installs via official 3.4.1  tarball and via xen-unstable.hg  but, every time the most recent JF's pvops kernel had been built to



support Dom0. Problem with hot-plug scripts was gone far away.
My question :-
What kernel is supporting your Dom0 ?

Boris.
P.S. Seems to me , that was kernel related problem in June.

- udev version is 141 (udevadm info -V)

- There is only a /etc/udev directory. It had two files : xend.rules
and xen-backend.rules. Removing them didn't help.




- I use pvops kernel. And, I use - make install-xen and make
install-tools PYTHON_PREFIX_ARG=""

- Following is the output from "udevadm monitor" :
KERNEL[1255816932.742809] add      /devices/vbd-22-2049 (xen-backend)
