[Xen-devel] [PATCH] Fix buildsystem to detect udev > version 124
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.

Re: [Xen-devel] [PATCH] Fix buildsystem to detect udev > version 124
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.

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.

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).

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.

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.

[Xen-devel] "Hotplug Scripts not working ..." error on jaunty
Hello, Dulloor schrieb:> 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.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?

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.

Re: [Xen-devel] Re: "Hotplug Scripts not working ..." error on jaunty
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. -dulloor On Sun, Oct 18, 2009 at 3:00 AM, Boris Derzhavets <bderzhavets@yahoo.com>wrote:> Please, tell how you setup Xen 3.4.1 or Xen Unstable on 9.04 server ? > > Boris. > > P.S.

Re: [Xen-devel] Re: "Hotplug Scripts not working ..." error on jaunty
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). -dulloor On Sun, Oct 18, 2009 at 3:48 AM, Boris Derzhavets <bderzhavets@yahoo.com>wrote:> > I will try 9.04-Server (not sure if it will help though) > 1.

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.

Dahlhaus" <mad@wol.de>, "Xen-devel" <xen-devel@lists.xensource.com> Date: Sunday, October 18, 2009, 3:09 AM 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. -dulloor On Sun, Oct 18, 2009 at 3:00 AM, Boris Derzhavets <bderzhavets@yahoo.com> wrote: Please, tell how you setup Xen 3.4.1 or Xen Unstable on 9.04 server ?

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. --- On Sat, 10/17/09, Dulloor <dulloor@gmail.com> wrote: From: Dulloor <dulloor@gmail.com> Subject: [Xen-devel] Re: "Hotplug Scripts not working ..." error on jaunty To: "Marc - A.
