Hi Daniel,
For now (IceHouse), it's not possible to boot from iso and attach volume
after boot. Libvirt present ISO disk via an IDE controller (/dev/hda)
and new volume try to be added as IDE too (/dev/hdb).
Do you mean that with the new block device mapping code, we will be able
to boot from ISO

Hi Daniel,
Thanks for the feedback. I have two questions:
1. Is it available in Havana?
2. Is it possible to to say that the glance image should be fetched to a
CDROM device (and disk file named 'iso'), and the root disk should be
created blank according to the flavor settings (disk file named 'di

Vish,
Exactly. Snapshots is the main reason why I started to modify Nova.
There's a high probability that we will contribute our work to Nova nearest
time. Meanwhile I'm ready to participate in all the discussions.

Hi guys,
In the Hyper-V driver camp we waited to add the boot from ISO feature because
of this issue.
Booting from ISO w/o local storage is almost useless for most scenarios.
It'd be great if we could reach consensus on this and propose some consistent
BPs for all supported drivers in early K-
I think we should discuss adding/changing this functionality. I have had many
new users assume that booting from an iso image would give them a root drive
which they could snapshot. I was hoping that the new block device mapping code
would allow something like this, but unfortunately there isn’t
Hi Vish!
Appreciate your feedback! Are there some significant pitfalls that forced
Nova team to decide that?
Currently I'm testing my local nova modifications to get real boot from ISO
functionality like described in the spec. I'm fetching ISO image from
glance into the separate file under the in
This is somewhat confusing, but long ago the decision was made that booting
from an ISO image should use the ISO as a root drive. This means that it is
only really useful for things like live cds. I believe you could use the new
block device mapping code to create an instance that boots from an
Hi Folks,
Could someone please share his experience with Nova "Boot from ISO" feature
[1].
We test it on Havana + KVM, uploaded the image with DISK_FORMAT set to
'iso'. Windows deployment does not happen. The VM has two volumes: one is
config-2 (CDFS, ~400Kb, don't know what that is); and the sec
