I have just run though the same process on a different engine
controlling a single node. Not changing anything on the Setup Host
Networks screen, it closes successfully when I click OK. Trying to
add the sandbox network to em1 gives the error "Error while
executing action Setup Networks: Internal oVirt Engine Error". This
shows up in engine.log: <<SNIP>>
[A side note: is it wise to keep DEBUG on VDSM logs? If not, is
there
an easy way to shut it off? That is an awful lot of traffic and
might explain why my nodes ran so slow when I was booting off of USB
sticks.]
Since you're running off of a USB stick, which is probably limited in
write bandwidth (USB interface + flash performance).
It would probably be wise to turn it to a higher level, and only turn to DEBUG when you
encounter a problem and can reproduce it (the downside is that you of course will not log
error that you can't reproduce).
The upside is that you'll save your stick's life (since flash chips have a limited
number of writes per cell) and it will work faster (less blocking on log IO until the log
is written).
You can change the log levels in /etc/vdsm/logger.conf
I would also suggest to turn down libvirt's log level for the same reasons.
It seems to me (not sure about this one) that you can do that by adding this line to
vdsm.conf:
libvirt_log_filters = 2 :libvirt 2:remote
So, all that seems to be consistent with Igor's comments and
I'll
have to do some fancy dancing to get this setup once I get past the
other bug. It would be nice if the GUI relayed the error " Setup
attached more than one network to nic em1, some of which aren't
vlans " from VDSM to the user, or some clearer translation, but it
sounds like that is on the way based on Moti's comments about the
nightly's, so I'll let it drop.
This bug was fixed, please see
https://bugzilla.redhat.com/show_bug.cgi?id=851134
In oVirt 3.2 (your DC has to be 3.2 as well) you can change the management network to be
VLANd or non-VM network, and use the "Sync Network" feature (part of the setup
networks process) to apply the change on the host. Then you'll be able to add a

(Remember that if the management network is VLAN'd on the host then it has to be
handled somehow so that the engine can communicate with it otherwise you'll lose
connectivity to the host)
This engine and node were built last week and the process went much
more smoothly than this first engine having problems. For the
problematic engine, which I setup a couple of months ago, the
CentOS6 packages had bunch of broken symlinks to jars that were on
the system, but not where the symlinks expected them to be. That
appears to have been fixed as of least week when I setup this second
engine. To fix it on the first, I manually created symlinks where
the broken ones were pointed rather than messing with any symlinks
created by the packages.
I wonder now if the packages on the bad engine (which are up to
date)
would have created different symlinks where I did and mine are
blocking them from being created. I can rebuild the engine server if
needed, but I would appreciate if some one can confirm that this
error is consistent with a wrong version of a jar or some similar
potential issue. Of course, I would also appreciate if there is a
simpler solution. =)
