I can't speak to other people, but the lack of "ovirt-shell" for 4.4 is a
deal-breaker for me to upgrade at this time, and probably for the
forseeable future.  I've been working on migrating my mail server for 3
years now and still haven't finished that; migrating ovirt to a new
platform that requires new startup support??  Haha.

Granted, I suspect SOME of the reasons I have this script might be
implemented in 4.4 (e.g. auto-start of VMs).  However, my understanding of
the auto-start feature is that it's really an auto-restart -- it will
restart a VM that was running if the datacenter crashes, but if I shut it
down manually and then "reboot" the cluster, those VMs wont come back
automatically.  As I am on a single-host system, I need it to start from a
clean shutdown and bring up all the VMs in addition to dealing with
power-outage reboots.

I work from the "if it aint broke, don't fix it" camp.  So I think I'm
going to stick with 4.3 until I can't anymore.

I am happy to share my startup script if someone else wants to port it to
work with 4.4.  :-)
