Royce has created the structure to add/list/lookup cdrom devices in the
guests.
There is a patch in the list (still under revision) with the code:
" Kimchi-devel] [PATCH 0/5] cdrom: support add and query cdrom "
This RFC aims to continue the second part of this work and modify the
API to
allow user to change (UPDATE/POST) attached cd ISOs and delete (DELETE)
cdrom devices.
If necessary I can continue the Royces work.
Aline has suggested to use the API as "/vms/<name>/storages" :
"""
. . . Maybe we can use /vms/<name>/storages
That way we can use the same API to add/remove different kind of
storages to the vm: cdrom, scsi disk, ide disk, etc ...
"""
This is the first decision here
(1) Use api as follow ?
(I propose to use API params to differentiate the storages, like
'?type=cdrom')
**URI:** /vms/*:name*/storages
* **GET**: Retrieve all storages attached to the VM
* **POST**: Attatch new storage to specified virtual machine.
* name : The name of the storage in the VM.
* type: The type of the storage: cdrom, disk
* path *(optional)*: Path of ISO or DISK.
### Sub-resource: storage
**URI:** /vms/*:name*/storage/*:name*
* **GET**: Retrieve the storage information
* path: Path of the storage
* type: Type of the storage
* **PUT**: Update storage information
* name *(optional)*: The name of the storage in the VM.
* path *(optional)*: Path of ISO or DISK.
* **DELETE**: Remove the storage
Examples:
UPDATE {'path': ''} /vms/vm-1/storage/cdrom-1--> to eject the iso
UPDATE {'path': '/root/ubuntu.iso'} /vms/vm-1/storage/cdrom-1-->to
change or insert a media
POST {'path':'abcd', 'bus': 'ide', 'name':
'cdrom-2'} /vms/vm-1/storage
--> to attach a new cdrom
DELETE {} /vms/vm-1/cdroms/cdrom-1-->to detach a cdrom
(2) Should be possible to add and remove storages with the guest running
? (Like hot plug)
Does libvirt provide this ?
(3) The new attached isos should be shown in the guests like changing a CD ?
(4) The specification mention tuning of the devices. Should tuning be
always done in the background, or
allow users to specify tuning parameters ?
