Hello, I'm about to write a new feature to Kimchi. It will allow users to define any existing volume group as a storage pool, where guests will be able to create logical volumes into it. NOTE: VGs already in use as storage pool won't be listed. I read Pooja's "[RFC] Proposal to manage Physical Volumes on Ginger", and now I think all LVM code should be implemented in WOK so both plugins (Kimchi/Ginger) could take advantages from that. API: Collection: /plugins/kimchi/host/vgs Method: GET Returns: list of vgnames: [vgname1, vgname2] Resource: /plugins/kimchi/host/vg/vgname Method: GET Returns: dict { vgname, size, free_size, [PV partition list, like: sda4, sdb3], [LV name list, like: lv_root] } Resource: /plugins/kimchi/storagepools/vgname Method: POST data: { vgname, storagepool_name, type=logical } The frontend, I think we could have a table indicating all available devices available for a logical storage pool, for example: Define a New Storage Pool 1. Storage Pool Name +-----------------------------------------+ | mypool | +-----------------------------------------+ The name used to identify the storage pools, and it should not be empty. 2. Storage Pool Type +-----------+ | LOGICAL | +-----------+ 3. Device path +-------+-------+---------------+---------------+ | |device | size | free size | +-------+-------+---------------+---------------+ | () | sdb | 50 GiB | 50 GiB | +-------+-------+---------------+---------------+ | () | sdc | 10 GiB | 8 GiB | +-------+-------+---------------+---------------+ | () | vg_a | 20 GiB | 18 GiB | +-------+-------+---------------+---------------+ +--------+ | Create | +--------+
