Previous _ was monkey patched into builtins whenever certain modules were imported. This removes that and simply imports it when it is needed. Change-Id: I0af2c6d8a230e94440d655d13cab9107ac20d13c

One-time script to populate VDI.other_config.
|
|
|
|
We use metadata stored in VDI.other_config to associate a VDI with a given
|
|
instance so that we may safely cleanup orphaned VDIs.
|
|
|
|
We had a bug in the code that meant that the vast majority of VDIs created
|
|
would not have the other_config populated.
|
|
|
|
After deploying the fixed code, this script is intended to be run against all
|
|
compute-workers in a cluster so that existing VDIs can have their other_configs
|
|
populated.
|
|
|
|
Run on compute-worker (not Dom0):
|
|
|
|
python ./tools/xenserver/populate_other_config.py [--dry-run|--verbose]
