I've read through this thread. Is there a consensus here? When I first
started on xen it used the files in /etc/xen/vm for configs, and to
autostart on boot you would put a softlink under /etc/xen/auto. 

With newer versions (I'm on 3.2.x) I'm using xenstore, but I don't like
the process. 

1) I create a new domU with virt-manager
2) I then shutdown the domU 
3) save a conf of the domU: xm list -l  [domU name] > [domU name].conf
4) edit this conf file for the start and stop lines
5) remove the domU from virt-manager
6) reinstall it with: xm new -F ï[domU name].conf

I really don't like this process at all and it doesn't work 100% of the
time for setting a domU to auto start. Plus, with it set this way I
can't restart xend without hosing the running domUs. I think if I change
the stop to ignore it would help. Drawback is I'd have to manually
shutdown all the domU's before restarting the server. 

Right now I have memory issues on two of my servers. I need to reboot
both servers, which affects roughly 20 domU's, both linux pv's and
windows hvm's. I don't know for sure, but it seems that restarting xend
might fix the problem for me. 

It was much nicer when it was a simple soft link in auto to the config
in vm. From this thread it sounds like you can still do this? Does that
mean no more virt-manager?

Should I be doing this a different way?

Thanks,
James
ps- sorry this got so long....
