|
- Get inventory hosts from the local virtualbox installation.
|
|
- Uses a YAML configuration file that ends with virtualbox.(yml|yaml) or vbox.(yml|yaml).
|
|
- The inventory_hostname is always the 'Name' of the virtualbox instance.
|
|
- Groups can be assigned to the VMs using C(VBoxManage). Multiple groups can be assigned by using V(/) as a delimeter.
|
|
- A separate parameter, O(enable_advanced_group_parsing) is exposed to change grouping behaviour. See the parameter documentation for details.

|
description:
|
|
- The default group parsing rule (when this setting is set to V(false)) is to split the VirtualBox VM's group based on the V(/) character and
|
|
assign the resulting list elements as an Ansible Group.
|
|
- Setting O(enable_advanced_group_parsing=true) changes this behaviour to match VirtualBox's interpretation of groups according to
|
|
U(https://www.virtualbox.org/manual/UserManual.html#gui-vmgroups).
|
|
Groups are now split using the V(,) character, and the V(/) character indicates nested groups.
|
|
- When enabled, a VM that's been configured using V(VBoxManage modifyvm "vm01" --groups "/TestGroup/TestGroup2,/TestGroup3") will result in
|
|
the group C(TestGroup2) being a child group of C(TestGroup); and
|
|
the VM being a part of C(TestGroup2) and C(TestGroup3).
