Hi,
Additional information:
After removing and re-running engine-setup, I try once again to run
ovirt-engine. I get the following error in the logs:
==> /var/log/ovirt-engine/console.log <==
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Nothing else, unfortunately, and I have no idea how to debug JBoss AS to
figure out what's going wrong.
Are there any requirements in terms of the JRE which aren't specified in
the quick start guide?
Thanks,
Dave.

It turns out, in /var/log/messages, that I have these error messages:

Sep 21 14:00:59 clare pg_ctl[5298]: HINT: This error usually means
that PostgreSQL's request for a shared memory segment exceeded your
kernel's SHMMAX parameter. You can either reduce the request size or
reconfigure the kernel with larger SHMMAX. To reduce the request
size (currently 36519936 bytes), reduce PostgreSQL's shared memory
usage, perhaps by reducing shared_buffers or max_connections.
Sep 21 14:00:59 clare pg_ctl[5298]: If the request size is already
small, it's possible that it is less than your kernel's SHMMIN
parameter, in which case raising the request size or reconfiguring
SHMMIN is called for.

I increased the kernel's SHMMAX, and engine-cleanup worked correctly.
Has anyone else experienced this issue?
Yes, not related to oVirt but on a database server also running
Postgres. It seems that either the package maintainer is very
conservative or postgres itself is. Standard on the Debian 6 server was
also very low shmmax.
What is the OS you run ovirt-engine on?
When I re-run engine-setup, I also got stuck when reconfiguring NFS -
when engine-setup asked me if I wanted to configure the NFS domain, I
said "yes", but then it refused to accept my input of "/mnt/iso" since
it was already in /etc/exports - perhaps engine-cleanup should also
remove ISO shares managed by ovirt-engine, or else handle more
gracefully when someone enters an existing export? The only fix I
found was to interrupt and restart the engine set-up.
Just switch to a different terminal and edit /etc/exports and continue
engine-setup.
Also, I have no idea whether allowing oVirt to manage iptables will
keep any extra rules I have added (specifically for DNS services on
port 53 UDP) which I added to the iptables config. I didn't take the
risk of allowing it to reconfigure iptables the second time.
After all that, I got an error when starting the JBoss service:
Starting JBoss Service... [ ERROR ]
Error: Can't start the ovirt-engine service
Please check log file
/var/log/ovirt-engine/engine-setup_2012_09_21_14_28_11.log for more
information
And when I checked that log file:

And when I check the system journal, we're back to the service starts,
but the PID mentioned in the PID file does not exist.
Any pointers into how I might debug this issue? I haven't found
anything similar in a troubleshooting page, so perhaps it's not a
common error?
Cheers,
Dave.
Are you following the setup instructions from the Wiki?
I have done that a couple of times now and haven't had problems sofar.
Had lots of problems with the pre-3.1 releases though.
