| `admin.vm.CreateInPool.<class>` | `dom0` | template | `name=<name> label=<label> `<br/>`pool=<pool> pool:<volume>=<pool>` | - | either use `pool=` to put all volumes there, <br/>or `pool:<volume>=` for individual volumes - both forms are not allowed at the same time
| `admin.vm.CreateDisposable` | template | - | - | name | Create new DisposableVM, `template` is any AppVM with `dispvm_allowed` set to True, or `dom0` to use default defined in `default_dispvm` property of calling VM; VM created with this call will be automatically removed after its shutdown; the main difference from `admin.vm.Create.DispVM` is automatic (random) name generation.
| `admin.property.Get` | `dom0` | property | - | `default={True|False} `<br/>`type={str|int|bool|vm|label|list} <value>` | Type `list` is added in R4.1. Values are of type `str` and each entry is suffixed with newline character.
| `admin.property.GetAll` | `dom0` | - | - | `<property-name> <full-value-as-in-property.Get>\n` | Get all the properties in one call. Each property is returned on a separate line and use the same value encoding as property.Get method, with an exception that newlines are encoded as literal `\n` and literal `\` are encoded as `\\`.
| `admin.property.GetDefault` | `dom0` | property | - | `type={str|int|bool|vm|label|list} <value>` | Type `list` is added in R4.1. Values are of type `str` and each entry is suffixed with newline character.
| `admin.vm.property.Get` | vm | property | - | `default={True|False} `<br/>`type={str|int|bool|vm|label|list} <value>` | Type `list` is added in R4.1. Each list entry is suffixed with a newline character.
| `admin.vm.property.GetAll` | vm | - | - | `<property-name> <full-value-as-in-property.Get>\n` | Get all the properties in one call. Each property is returned on a separate line and use the same value encoding as property.Get method, with an exception that newlines are encoded as literal `\n` and literal `\` are encoded as `\\`.
| `admin.vm.property.GetDefault` | vm | property | - | `type={str|int|bool|vm|label|type} <value>` | Type `list` is added in R4.1. Each list entry is suffixed with a newline character.
| `admin.vm.feature.Set` | vm | feature | value | - |
| `admin.vm.tag.List` | vm | - | - | `<tag>\n` |
| `admin.vm.tag.Get` | vm | tag | - | `0` or `1` | retcode? |
| `admin.vm.tag.Remove` | vm | tag | - | - |
| `admin.vm.tag.Set` | vm | tag | - | - |
| `admin.vm.firewall.Get` | vm | - | - | `<rule>\n` | rules syntax as in [firewall interface](/doc/vm-interface/#firewall-rules-in-4x) with addition of `expire=` and `comment=` options; `comment=` (if present) must be the last option
| `admin.vm.firewall.Set` | vm | - | `<rule>\n` | - | set firewall rules, see `admin.vm.firewall.Get` for syntax
| `admin.vm.firewall.Reload` | vm | - | - | - | force reload firewall without changing any rule
| `admin.vm.device.<class>.Attach` | vm | device | options | - | `device` is in form `<backend-name>+<device-ident>`<br/>optional options given in `key=value` format, separated with spaces; <br/>options can include `persistent=True` to "persistently" attach the device (default is temporary)
| `admin.vm.device.<class>.List` | vm | - | - | `<device> <options>\n` | options can include `persistent=True` for "persistently" attached devices (default is temporary)
| `admin.vm.device.<class>.Available` | vm | device-ident | - | `<device-ident> <properties> description=<desc>\n` | optional service argument may be used to get info about a single device, <br/>optional (device class specific) properties are in `key=value` form, <br/>`description` must be the last one and is the only one allowed to contain spaces
| `admin.pool.volume.CloneFrom` | `dom0` | pool | vid | token, to be used in `admin.pool.volume.CloneTo` | obtain a token to copy volume `vid` in `pool`;<br/>the token is one time use only, it's invalidated by `admin.pool.volume.CloneTo`, even if the operation fails |
| `admin.vm.volume.ImportWithSize` | vm | volume | `<size_in_bytes>\n<raw volume data>` | - | new version of `admin.vm.volume.Import`, allows new volume to be different size |
| `admin.vm.volume.CloneFrom` | vm | volume | - | token, to be used in `admin.vm.volume.CloneTo` | obtain a token to copy `volume` of `vm`;<br/>the token is one time use only, it's invalidated by `admin.vm.volume.CloneTo`, even if the operation fails |
| `admin.vm.volume.CloneTo` | vm | volume | token, obtained with `admin.vm.volume.CloneFrom` | - | copy volume pointed by a token to `volume` of `vm` |
| `admin.backup.Execute` | `dom0` | config id | - | - | config in `/etc/qubes/backup/<id>.conf`, only one backup operation of given `config id` can be running at once |
| `admin.backup.Info` | `dom0` | config id | - | backup info | info what would be included in the backup
- there is no provision for `qvm-run`, but there already exists `qubes.VMShell` call
- generally actions `*.List` return a list of objects and have "object
identifier" as first word in a row. Such action can be also called with "object
identifier" in argument to get only a single entry (in the same format).
- closing qrexec connection normally does _not_ interrupt running operation; this is important to avoid leaving the system in inconsistent state
- actual operation starts only after caller send all the parameters (including a payload), signaled by sending EOF mark; there is no support for interactive protocols, to keep the protocol reasonable simple
## 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 `admin.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
