Now that my authentication problems seems to be fixed, it's back on track with
trying to boot my first instance..

Thanx.

Ok, so I created an empty, bootable volume. Worked just fine it seems.
I then used that when creating the instance (from Horizon).
Still the same error - Block Device Mapping is Invalid.

If I understand you correctly, this is a Cinder volume, right? Because of
the "@lvm.." part?
How can I create a local volume?
Looking under "System Information -> Block Storage Services" I see only
Cinder services..

Thanx, I've read something similar so I'm aware of the differences and
what they do. This one I'm going to read in more detail, because it HAD
more detail! :)

It was commented out, but just for the sake of it I un-commented it..

Thanx. That was actually halfway to actually be "documentation". I'll bookmark
that.

Ok, that's different! I'm not running Glance on my Compute, only on my Control.
Which of these should I run on the Compute and which one on the Control?
The documentation (one of many I follow:
http://docs.openstack.org/draft/install-guide-debconf/common/get_started_image_service.html)
doesn't say. Only which ones to install
on the Control.

Ok, I'll keep that in mind, thanx.
Now, this might be a stupid question, but it actually only occurred to me just
now
when I looking at that missing net error. I haven't really setup my network,
just
"winged" it. I' pretty sure it's not even close to working (I need to do more
studying in the matter - I still don't have a clue about how things is supposed
to work in/on the OpenStack side of things).
I've postponed it because I desperately need ANY success story - creating an
instance, even if it won't technically work would help a lot in that. I figured
it should at least TRY to start.. And I _ASUME_ (!!) that as long as the Control
can talk to the Compute and "tell" it what to do (such as "attach this
volume/image"),
it should at least be able to be created. I'm guessing the networking (Neutron)
in OS is for the _instance_, not for administration etc. Or, did I misunderstood
(the little I've read and actually understood about it :)?
