It finally works. The problem was the flag checks while looking for the
ISO SR.
inside the find_iso_sr method (in nova/virt/xenapi/vm_utils.py), I found
that the ISO SR must have these settings:
content type: iso
other-config:i18n-key=local-storage-iso
As far as I know, this wasn't documented anywhere. Hope this can be
useful for people from the future.
cheers,

Off the top of my head, I'd look to see if the compute node can see
that ISO SR.

Hi Donal, hi all,
I'm trying to test the Boot From ISO feature. So I've set a XenServer
host and installed a Ubuntu 11.10 PV DomU in it.
Then I used the following commands but, as you can see in the attached
nova-compute log excerpt, there was a problem.
glance add name=fedora_iso disk_format=iso <
../Fedora-16-x86_64-Live-LXDE.iso
ID: 4
nova boot test_iso --flavor 2 --image 4
I can see the ISO images using "nova list" but not using "glance index".
The error seems to be: 'Cannot find SR of content-type ISO'. However,
I've set a NFS ISO Library using XenCenter, so that there is an actual
ISO content-typed SR. How to tell OpenStack to use this SR for the ISO
images I post using glance?
Any clue? I feel I'm rather close to make it work.
thanks,
michaël

Hi Michaël,
"Boot from ISO" should be ISO image agnostic. The feature overcomes
restrictions placed on the distribution of modified Windows' images.
People can use their ISO instead, but they may still need to use
dedicated hardware.
You should have no problem with a Linux distribution.
However, I wrote it for XenAPI, so we need someone to duplicate the
work for KVM and VMWare.

Hi all,
I'm very interested in the "Boot From ISO" feature described here:
http://wiki.openstack.org/bootFromISO
In a few words, it's about the ability to boot a VM from the CDROM
with an ISO image attached. A blank hard disk being attached to
install the OS files in it.
I've got some questions about this:
1. Is the feature available today using a standard Diablo install?
I've seen the code about this feature is stored under nova/tests and
glance/tests. Does this mean it isn't finished yet and could only be
tested under specific conditions? Which ones?
2. the spec tells about a Windows use case. Why just Windows? What
should I do to test with a Linux distribution?
3. I can see here
<http://bazaar.launchpad.net/%7Ehudson-openstack/nova/trunk/revision/1433?start_revid=1433>
that the Xen hypervisor only has been impacted by the source code
changes. Are KVM and VMWare planned to be supported in the future? May
I help/be helped to develop KVM and VMWare support for this 'Boot From
Iso' feature?
Any help appreaciated
thank you,
michaël
