libxl: set script field of libxl_device_disk
|
|
|
|
Add a hack to the libvirt libxl driver to set
|
|
libxl_device_disk->script when the disk configuration starts
|
|
with some well-known Xen external block scripts: dmmd, drbd,
|
|
and npiv.
|
|
|
|
For more details, see bsc#954872 and FATE#319810
