Re: boot from ISO

 

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,

michaël

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
