[Fedora-xen] starting XEN with /usr mounted through NFS

[Luca]

Hi all,
 I'm trying to boot Xen mounting the /usr directory through NFS.
I get though the following error:

Starting xen daemons: xenstored blktapctrl xenconsoled xendTraceback (most
recent call last):
File "/usr/sbin/yum-updatesd", line 39, in <module>
  import gamin
File "/usr/lib64/python2.5/site-packages/gamin.py", line 39,
  err = _gamin.Errno()

TabError: inconsistent use of tabs and spaces in indentation


Does anyone know what that means?

Thanks,
 Luca
