[ovirt-users] Adding another host to my cluster

Hi Gervais,

   Hmm, can you tar up the logfiles (/var/log/vdsm/* on the host you are 
installing on) and put them somewhere to look at?  Also, I found that 
starting VDSM from the command line is useful as it sometimes spits out 
error messages that don't show up in the logs.  I think the command I 
used was:
su -s /bin/bash vdsm
python /usr/share/vdsm/vdsm

My problem was that I customized the logging settings in /etc/vdsm/*conf 
to try and tone down the debugging stuff and had a syntax error.
