That's right, it's a Xen<b>Server</b> only feature. I insist on
XenServer because it's been implemented only inside the xenapi.<br>
If you wish to manage VMs using KVM or Xen hypervisor (the community
hypervisor packaged in Linux distributions), this will utilize the
libvirt API, and not XenAPI.<br>
<br>
So, one needs to use XenServer (btw, openstack works great with
XenServer 6.0 even if <a
href="http://docs.openstack.org/diablo/openstack-compute/admin/content/hypervisors.html">documentation
claims that the supported release is 5.5</a>) in order for the
XenAPI to be used.<br>
<br>
I made use of this <a
href="http://wiki.openstack.org/XenServerDevelopment">documentation</a>
in order to set up the environement. What is missing is that, in
order to activate the "<a
href="http://wiki.openstack.org/bootFromISO">Boot From ISO</a>"
feature, the SR elements on XenServer host must be configured that
way:<br>
<br>
1. create an ISO-typed SR, such as an NFS ISO library, for instance.
For this, using XenCenter is pretty easy. You need to export an NFS
volume from a remote NFS server. Make sure it is exported in RW
mode.<br>
2. on the host, find the uuid of this ISO SR:<br>
# xe host-list<br>
write the uuid down<br>
3. # xe sr-list content-type=iso<br>
locate the uuid of the NFS ISO library<br>
4. # xe sr-param-set uuid=<iso sr uuid>
other-config:i18n-key=local-storage-iso<br>
Even if an NFS mount point isn't local storage, you must specify
"local-storage-iso".<br>
5. # xe pbd-list sr-uuid=<iso sr uuid><br>
make sure the host-uuid from "xe pbd-list" equals the uuid of the
host you found at step 2<br>
<br>
then apply the <a
href="http://wiki.openstack.org/XenServerDevelopment#Configure_SR_storage">rest
of the tutorial</a> and publish an ISO image this way:<br>
glance add name=fedora_iso disk_format=iso container_format=bare
< Fedora-16-x86_64-netinst.iso<br>
nova boot test_iso --flavor <flavor ID> --image <image
ID><br>
<br>
I've posted this in the bug you filed, Anne.<br>
<br>
By the way, I'm going to work on porting this feature on libvirt API
and VMWare API (if nobody works on it yet).<br>
<br>
Is the config drive yet available for Diablo??<br>
<br>
cheers,<br>

<pre wrap="">Thanks for the info! I've logged bug 898682 [1] to ensure it gets
added to the documentation. Based on this note, is this a solution for
Xen only?
Is this the same as using a config drive? I had heard a config drive
works on KVM but not Xen.
If someone who's familiar with this area could work on the docs that
would be great.
Thanks,
Anne

<pre wrap="">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.

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

Subject: Re: [Openstack] boot from ISO
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:
<a class="moz-txt-link-freetext" href="http://wiki.openstack.org/bootFromISO">http://wiki.openstack.org/bootFromISO</a>
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 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
