Crash on describing EC2 volume backed image with multiple devices

[Feodor Tersin]

EC2 describe images crashes on volume backed instance snapshot which has several volumes:

$ euca-describe-images
euca-describe-images: error (KeyError): Unknown error occurred.

Steps to reproduce
1 Create bootable volume
$ cinder create --image <image-id> <size>

2 Boot instance from volume
$ nova boot --flavor m1.nano --block-device-mapping /dev/vda=<volume_id>:::1 inst

3 Create empty volume
$ cinder create 1

4 Attach the volume to the instance
$ nova volume-attach inst <empty-volume-id> /dev/vdd

5 Create volume backed snapshot
$ nova image-create inst sn-in

6 Describe EC2 images
$ euca-describe-images

Thank you for the very straight forward replication scenario.

[Sean Dague (sdague)]

Set to triaged as this should be easy to reproduce.

    Fix pci_request_id break the upgrade from icehouse to juno

    commit a8a5d44c8aca218f00649232c2b8a46aee59b77e add pci_request_id
    as one item for the request_network tuple. But the icehouse code
    assume only three items in the tuple.

    This patch filters pci_request_id out from the tuple.

    Fix broken cert revocation

    Cert revocation was broken by
    32b0adb591f80ad2c5c19519b4ffc2b55dbea672. os.chdir() never returns
    anything, so this method would always raise an exception. The proper
    way to handle an error from os.chdir() is to catch OSError.

    There were existing tests for this code, but they conveniently mocked
    os.chdir() to return values that are never actually returned. The
    tests were fixed to match the real behavior.

    Update rpc version aliases for juno

    Update all of the rpc client API classes to include a version alias
    for the latest version implemented in Juno. This alias is needed when
    doing rolling upgrades from Juno to Kilo. With this in place, you can
    ensure all services only send messages that both Juno and Kilo will
    understand.
