boot from image (creates as a new volume) does not work

[Dafna Ron]

trying to launch an instance from horizon and selecting boot from image (creates a new volume) fails each time with the following error in log:

HTTP exception thrown: Invalid imageRef provided.

I have used this image to launch other "regular" instances

Need to verify and diagnose for RC1

[Matthias Runge (mrunge)]

During launch, states cycle from build via network to Block Device Mapping, where it fails.

Creating block devices from image fails, too.

[Matthias Runge (mrunge)]

I assume, this is connected to bug https://bugs.launchpad.net/bugs/1231887

[Matthias Runge (mrunge)]

when using an iso, this works for me. Seems to be a bug in cinder.

[nick dallamora (ndallamora)]

is there a 1:1 workaround for this? i'm experiencing this bug and am also unable to attach a volume to the instance.

[Lin Hua Cheng (lin-hua-cheng)]

This is a different issue from the bug marked as duplicate.

When the "boot from image (create a volume)" is selected, Horizon makes a call to novaclient servers.create() passing the BDM format (block_device_mapping_v2 as parameter). In this format, the imageID is passed in the block_device_mapping_v2 dict object instead of passing it directly to novaclient as imageRef parameter.

The BDM format is a Nova extension "os-block-device-mapping-v2-boot". If this is not enabled in Nova, it result to the error message reported "Invalid imageRef provided".

Reference https://wiki.openstack.org/wiki/BlockDeviceConfig#API_data_model_and_backwards_compat_issues

We should be checking the Nova extensions and hide the option to boot from image (create a volume) if not supported.

[Lin Hua Cheng (lin-hua-cheng)]

I'm going to remove the link to the duplicate bug: bug #1231887. Since this is a different issue from Bock.

[Lin Hua Cheng (lin-hua-cheng)]

Dahna or Nick: Can you confirm if this is root case of your issue?

List the Nova V2 extensions and see if you can find "BlockDeviceMappingV2" there.

Is it havana-backport-potential?

    Add check for BlockDeviceMappingV2 nova extension

    Booting instance from image (creates a volume) option is using
    the new BDM format when submitting the create server request to
    Nova. Adding a check for Nova extensions if it is supported
    before displaying the option.
