Re: [Xen-devel] Changeset 19594 for Xen 3.4 build on Ubuntu Server 9.04 causes pygrub doesn't return any data anymore

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

Per /usr/lib/python2.6/site.py:-

For Debian and derivatives, this sys.path is augmented with directories
for packages distributed within the distribution. Local addons go
into /usr/local/lib/python<version>/dist-packages, Debian addons
install into /usr/{lib,share}/python<version>/dist-packages.
/usr/lib/python<version>/site-packages is not used.

It is different from /usr/lib/python2.5/site.py

With Config.mk:-

PYTHON =  python
PYTHON_PREFIX_ARG =

Packages gets installed into /usr/local/lib/python2.6/dist-packages:-

root@ServerJaunty:/usr/local/lib/python2.6/dist-packages# ls -ld xen
drwxr-sr-x 9 root staff 4096 2009-05-15 10:35 xen


Xend starts fine, pygrub doesn't fail. Xen host seems to be OK.
But, "xm create -c DomU.cfg" doesn't work any more,even with xenified kernel. DomU gets paused at startup and no matter of been upaused or no, finally crashes with message:-

"Hotplug scripts not working"

I believe Xen 3.4 has problem been installed on Ubuntu 9.04 Server (64-bit)
with python 2.6 installed with default settings.
Same situation will happen on any Debian derivative with Python 2.6

If i am wrong about that, please advise.

Boris.

Good.

But xm create now appears to work ?  It's possible that the fix didn't
take properly for pygrub.  Or perhaps that you are running a version
leftover from a previous attempt ?

What errors are in the hotplug logfile ?
