Comment 21 for bug 362691

PLease be aware of changeset 19594 in Xen Unstable
http://xenbits.xensource.com/xen-unstable.hg?rev/bf946cc3008b
With this patch applied Xen Unstable been built on top of Ubuntu 9.04 Server with python 2.6 (or python 2.5) now is able to start xend daemon, but appears unable to start any DomU due to "Hotplug scripts failure to work". Kernel 2.6.30-rc3-tip (supporting Xen in Dom0) just sends one bakend driver's message to dmesg report and report output freeze.
I am not python expert,but it seems like Python 2.6 ( 2.5 as well) setup is incorrect on 9.04. All issues described above disappear if Xen Unstable along with kernel 2.6.30-rc3-tip were built on top of Ubuntu 8.10 Server (Python 2.5). Suse's xen-ified kernel 2.6.27.5 behaves absolutely same way
as pvops enabled kernel .
