[one-users] instantiating template for Debian xen

[Antanas Masevicius]

Hello,

thanks Javier for the tip. I certainly lack knowledge how these disk
images work. Theres not too much info about them. I noticed there are
xen images in qcow2 format. What version of xen should i use to support
those properly?

As of "file:", i renamed image format from raw: to file: and passed that
problem as you suggested.  

Other issue was with "sched-cred" not being found. I uncommented line
with "sched-credit", ran 'onehost sync', but logs still complained about
"Error: Subcommand sched-cred not found!". I had to remove host
completely from configuarion and recreate it. Now debian xen image is in
running state.

best regards,
Antanas
