[pve-devel] [PATCH manager 06/17] add new DiskStorageSelector.js

[Dominik Csapak]

this is a wrapper for selecting a storage/disk image

it is a simple container with 4 form fields inside
which can be reused, whenever we need to select a storage for a disk,
image etc.

we have code similar to this four times already
(qemu image creation, lxc mp creation, qemu cloning, qemu efidisk
creation)

so it was time to refactor this and use the storage information from the
backend instead of hardcoding values in the frontend
