In case of any repo container going down any attempt to build venv will fail due to failure to gather facts for them. In order to overcome the issue defaults for venv_build_targets elements are defined along with ignoring any failures for fact gathering. However failed_when is used instead of ignore_errors as ignore_errors will invalidate facts for successfull hosts as well, while failed_when preserves result for successfull hosts. As a result venv_build_targets will be populated with `none-none-none` key which will inlcude all hosts that don't have required facts in place Change-Id: I271e6464133939be4e21110042cd489dc66c8d5d

# Auto generation process:

# * The current inventory hostname is inserted as the first build target

# and will be used if no other suitable targets are found.
|
|
# * It then iterates over the group defined by {{ venv_build_group }} and if any
|
|
# targets are found it will catagorize them by distro and cpu architecture
|
|
# and add them to the list of targets.
|
|
# * If no build target is found for matching the distro and cpu
|
|
# criteria of the active inventory item, the generator will fall
|
|
# back to using the active inventory host as the build target.

# NOTE: (cloudnull): While there may be multiple inventory items

# type, only one build target will ever be used.

|
# To make more than one build target effective,

# deployers should be using a shared file system
