trouble running xen-unstable

[Diwaker Gupta <diwakergupta@gmail.com>]

Hi everyone,

I've been running 2.0.6 for a while and thought would give the
upcoming 3.0 a try. The compile went fine, but I'm running into a lot
of problems when trying to run:

o when I first start xend, and do an xm list, it works fine
o after that I try doing an xm create, and it fails saying:
Error creating domain: I/O operation on closed file

/var/log/xend-debug.log reports:
  File "/home/diwaker/xen-unstable/orig/dist/install/usr/lib/python/xen/xend/XendDomainInfo.py",
line 504, in construct

  File "/home/diwaker/xen-unstable/orig/dist/install/usr/lib/python/logging/handlers.py",
line 104, in emit
ValueError: I/O operation on closed file

o after this, even an xm list fails

/var/log/xend.log doesn't show anything unusual.

I must say that this is machine is running really old sofware (RH9,
Python 2.2.2) -- but since the compile went ok, I'm hoping thats not a
problem. I've seen other people in the list mention the above error,
but for them it seems the operation actually went through.

Any ideas?
