Reference: https://github.com/kimchi-project/kimchi/wiki/Todo-1.2 https://github.com/kimchi-project/kimchi/wiki/customize-VM 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 ? Regards, Rodrigo Trujillo
