What is the output of the following python script on your machine? Mine
says "1". Could it be that your libvirt says "0"?

=============

      
>from vdsm import libvirtconnection
    
conn = libvirtconnection.get()
netXml = """<network>
 <name>test</name>
 <forward mode='passthrough'>
   <interface dev='em1'/>
 </forward>
</network>
"""

net = conn.networkDefineXML(netXml)
net.create()
print net.isPersistent()
net.destroy()
net.undefine()

libvir: Network Driver error : Network not found: no network with
matching uuid
Traceback (most recent call last):
 File "test.py", line 16, in <module>
   net.undefine()
 File "/usr/lib64/python2.7/site-packages/libvirt.py", line 2154, in
undefine
   if ret == -1: raise libvirtError ('virNetworkUndefine() failed',
net=self)
libvirt.libvirtError: Network not found: no network with matching uuid

So '0' :-((
Suppose that error isn't good either.
Should I downgrade to an earlier version of libvirt?
    

Please try. My guess is that this is a libvirt bug added by
http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=0211fd6e04cdc402da20818df54299c6ded3d3cb
in libvirt 1.0.1. More authoritative answer is expected by those added
to the CC line.

  
Went back to libvirt-0.10. from the danken repo and now it works. Will reinstall st01 in the same way as a test.

Thanks for the help and have a nice X-mas.
