[pve-devel] [PATCH qemu-server v2 3/3] Move importdisk from qm to API

[Dominic Jäger]

Additionally, add parameters that enable directly (avoiding the intermediate
step as unused disk) attaching the disk to a bus/device with all known disk
options.

Required to create a GUI for importdisk.

I'd rather avoid doing this here, i.e., the common shared code should not
do such transforming things specific for a single use case downstream..
That adds coupling, which should be avoided if possible.

Why can the import window instance not handle this?

sorry to catch this only now..

This was the first way that I found that resulted in a working prototype.  And
I wasn't sure if this is actually the right direction for this patch, so I left
it like that for the moment.

I'll think of a better way.

Re: [pve-devel] [PATCH widget-toolkit v2 1/3] EditWindow: Change url to 'importdisk' for import

[Dominic Jäger]

I think that doing this without changing anything in the shared code is not
trivial.  So it's still transforming the url [0], but not specific to the
import function anymore.

Of course I am still open for other approaches that I haven't seen yet :)
