+1 from me.
We are currently investigating how to use OpenStack with a FC SAN.

At the last couple volumes meetings, there was some discussion of the
desired behaviors of nova's boot from volume functionality. There were
a few use cases discussed, but there are probably plenty we didn't
think of, so it would be useful to get input from a larger audience.
What use cases for boot from volume are people interested in, and
which should nova support?
Here are a few use cases:
1) I use an existing instance to manually create a bootable volume
containing an OS there is no image for (and I cannot create an
image). I boot the new OS from the volume I created.
2) I create a bunch of new instances that have no ephemeral disks,
but are all based on the same image. The data from the image is
copied to a new volume for each new instance.
3) I have an instance that has no ephemeral disks, and stores
everything in a volume. I take periodic snapshots of the
volume. Later, my original instance becomes corrupted, and I want
to restore from the last known good snapshot I took. I boot a new
instance from a new volume created by cloning from the last
good snapshot.
