Havana: boot from ISO not working

[Ruediger Rissmann]

I have a problem booting an instance from an ISO image. This works well in our folsom cloud, but its not working on out havana cloud. I have an ISO image uploaded and try to create an instance from it. Images are store on an rbd volume. the instance hangs with

Boot failed: could not read the boot disk

I traced the problem down to the content of the libvirt.xml file. The problem seems to be the following config setting:

<disk type="network" device="disk">

If I create an instance from the same libvirt.xml file and just change the "disk" to "cdrom" the instance is booting.

You need to actually provide some technical info on what you were doing to get to this state.

eg at a minimum provide the output of 'glance image-show XXXX' for the image you are trying to use, and the full 'nova boot' command line you are using and/or output of 'nova show XXXX' for the instance in question. Also attach the glance.conf and nova.conf configuration files to the bug

I uploaded an ISO image to glance:

and now I try to boot it:
nova boot --flavor 1 --image 63dd32a7-7d8b-45b1-84af-f081e8fc0ccb "ISO test"

Here the libvirt.xml of the instance.
As you can see the device is set to "disk"
<disk type="network" device="disk">
If I change that to cdrom I can use virsh and create an instance from that.

Any updates to this?

[Ruediger Rissmann (ruediger.rissmann)]

I am in the process of setting up a new environment. Ill check if boot from ISO is working there once it is up and running.

Ruediger, did you get to setup a new environment to test the boot from ISO? If so, please post the observations here.
