Hi all,
I have the need to support a VM which (a) comprises multiple disk images, and
(b) boots off a disk which is not the first disk. I've read the docs, played
with:
nova boot --image (and also --ephemeral)
nova boot --block-device-mapping
nova boot --block-device and its boot_index
and I think that what I need is something like this:
nova boot --block-device=diskimage0,type=?? \
--block-device=diskimage1,type=?? \
--block-device=diskimage2,type=??,boot-index=0
On Havana h1 at least, all that seems to do is to rename the boot device from
vda to vdc. I see several launchpad entries in this vague area, but am left
wondering if this is beyond what is actually possible even in Icehouse (which
I have not yet tried).
Any clues welcomed.
Thanks, Shaheed
P.S. AFAIK, I am not interested in anything which is volume-centric in the
first instance, as I need the same images to be loaded by multiple instances.
