Xen devel - Nov 2004 - python exception when xend starts

Hi, I''m trying to get a Fedora Core 2 box running on a few instances of
Xen, and I''ve followed the documentation up to the part where
I''m
supposed to:

xend start

Which immediately produces this:

/lib/python/xen/xend/server/SrvDaemon.py:27: RuntimeWarning: Python C 
API version mismatch for module xen.lowlevel.xu: This Python has API 
version 1012, module xen.lowlevel.xu has version 1011.
  from xen.lowlevel import xu
/lib/python/xen/xend/server/channel.py:3: RuntimeWarning: Python C API 
version mismatch for module xen.lowlevel.xc: This Python has API version 
1012, module xen.lowlevel.xc has version 1011.
  import xen.lowlevel.xc; xc = xen.lowlevel.xc.new()
ERROR: Could not obtain handle on privileged command interface (2 = No 
such file or directory)
Traceback (most recent call last):
  File "/usr/sbin/xend", line 27, in ?
    from xen.xend.server import SrvDaemon
  File "/lib/python/xen/xend/server/SrvDaemon.py", line 40, in ?
    import channel
  File "/lib/python/xen/xend/server/channel.py", line 3, in ?
    import xen.lowlevel.xc; xc = xen.lowlevel.xc.new()
xen.lowlevel.xc.error: (2, ''No such file or directory'')



Any ideas?

Thanks,
-John

This looks like a Python versions issue.  Are you using the binary install?  
If so, you can probably fix this by rebuilding from source.  The build 
machine for the binary install runs RH9 and therefore has an older Python 
than you have.

HTH,
Mark

The version mismatches seem harmless -- we use Xen on FC2 all the
time. Once we''ve got some per-distro rpms made up we should be
able to avoid this.

Have you actually booted into xen/xenolinux? You should have a
/proc/xen/privcmd

You''ll also need to start xend as root.
