# Management API
*(This page is the current draft of the proposal. It is not implemented yet.)*
The API should be implemented as a set of qrexec calls. This is to make it easy
to set the policy using current mechanism.
## The calls

## General notes
- there is no provision for `qvm-run`, but there already exists `qubes.VMShell` call
## TODO
- something to configure/update policy
- notifications
- how to constrain the events?
- how to pass the parameters? maybe XML, since this is trusted anyway and
parser may be complicated
- how to constrain the possible values for `mgmt.vm.property.Set` etc, like
"you can change `netvm`, but you have to pick from this set"; this currently
can be done by writing an extension
- a call for executing `*.desktop` file from `/usr/share/applications`, for use
with appmenus without giving access to `qubes.VMShell`; currently this can be
done by writing custom qrexec calls
- maybe some generator for `.desktop` for appmenus, which would wrap calls in
`qrexec-client-vm`
