Hi,
This is an attempt to cleanup current behaviour of cloudinit online changes.
Currently, we setup cloudinit options as pending, until we generate the config
drive.
This is not 100% true, because some option like vm name, nic mac address can be
changed,
without going to pending, so user can't known if it need to regenerated it.
Also, some can are very difficult to handle, if you hotplug a nic but it's
failing,so pending,
then you defined an ipconfig, and then you revert hotplug.
or if you delete a nic, the ipconfig is no more displayed in the gui.
So, instead of setting cloudinit values in pending,
this patch serie copy the current cloudinit config in a new section
[special:cloudinit],
when the config drive is generated.
This is only an hint, to allow to display diff between the generated cloudinit
drive, and the current vm config.
A new specific cloudinit config api is added too, merging ipaddrX && netX mac
in same field, and displaying the diff between current and generated config.
Changelog V1:
- use [special:cloudinit] instead [CLOUDINIT] for section
- delete config section on drive removal
- config api: move code to new PVE::QemuServer::Cloudinit::get_pending_config
- config api: add "qm cloudinit pending" cli
- add update api to regenerate drive with 1 api call
- add cloudinit hotplug option
Changelog v2:
- fix trailing whitespace in first patch
- revert previous "cloudinit" check in snapshot name (":" character is already
forbidden)
