# HS-Fulda - sebastian.rieger@informatik.hs-fulda.de

# changelog:
# V1.1 added injection of config defined in VM Maestro using config-drivex
# V1.11 fixed device mapping of extracted partitions, fixed problems with stale swi directory
# V1.12 rc.eos now supports e1000 and virtio as vnic types (virtio is supported in vEOS >=4.14.5F)
# V1.2 added dynamic handling of device mapping of extacted partitions
# V1.21 checking whether it safe to unmount working directories
# V1.3 added support to delete existing image with the same name and generating the default nova flavor
# V1.31 added support for newer glance releases (e.g. kilo) used in VIRL 1.0.0
# V1.32 changed the extension of the bootloader iso to match the size of the partitions to be injected
# V1.4 support for variable VEOS image sizes (as requested by @Jade_Deane to use custom VEOS images)
# V1.5 automatic import of subtype and creation of flavors based on image name,
# short instructions on how to use the image and hint to default node configuration,
# removed detection of existing image as new VIRL version supports multiple versions
# V1.1 added injection of config defined in VM Maestro using config-drivex
