Enables the use of Logical Volumes as disk backends. It uses an existing volume group and has no support for creating a new one. It will not override an existing logical volume and fail gracefully. The lv is created, activated and then mounted as a loop device. The boostraping process is then launched on the loop device. Once the process is completed, the lv is unmounted and desactivated. The created lv will be deleted should the boostraping process fail. The lv must be activated before use. A manifest has been included for testing purposes.

|
|
The `KVM <http://www.linux-kvm.org/page/Main_Page>`__ provider creates
|
|
virtual images for Linux Kernel-based Virtual Machines. It supports the
|
|
installation of `virtio kernel
|
|
modules <http://www.linux-kvm.org/page/Virtio>`__ (paravirtualized
|
|
drivers for IO operations).
|
|
It also supports creating an image with LVM as a disk backend.

Provider

|
~~~~~~~~
|
|
|
|
- ``virtio``: Specifies which virtio kernel modules to install.
|
|
``optional``
|
|
- ``logicalvolume``: Specifies the logical volume where the disk image will be built.
|
|
``volumegroup``: Specifies the volume group where the logical volume will be stored.
|
|
These options should only be used if ``lvm`` was given as a disk backend.
