volume fails to build in tempest.scenario.test_volume_boot_pattern.TestVolumeBootPatternV2.test_volume_boot_pattern

[Nuno Santos]

I was able to reproduce it consistently if the size of the image
that's originally used to boot an instance from which the snapshot
is taken is bigger than the volume_size specified in tempest.conf
(defaults to 1).

Here's the resulting error (several similar errors):

tempest.scenario.test_volume_boot_pattern.TestVolumeBootPatternV2.test_volume_boot_pattern[compute,id-557cd2c2-4eb8-4dce-98be-f86765ff311b,image,smoke,volume]

    Specify snapshot size when creating volume

    To avoid volume creation failures due to the default size being
    insuficient, specify the snapshot size when creating a volume
    from a snapshot.
