platform (MRW): acpi: true; apic: true; pae: true; nx: false
allowed-operations (SRO): pause; clean_shutdown; clean_reboot; \
hard_shutdown; hard_reboot; suspend
The platform parameter has a list of items that represent key/value pairs. The key names are followed by a
colon character (:). Each key/value pair is separated from the next by a semicolon character (;). The M preceding
the RW indicates that this is a map parameter and is readable and writable. The allowed-operations
parameter has a list that makes up a set of items. The S preceding the RO indicates that this is a set parameter
and is readable but not writable.
In xe commands where you want to filter on a map parameter, or set a map parameter, use the separator : (colon)
between the map parameter name and the key/value pair. For example, to set the value of the foo key of the
other-config parameter of a VM to baa, the command would be
xe vm-param-set uuid=<VM uuid> other-config:foo=baa
Note:
In previous releases the separator - (dash) was used in specifying map parameters. This syntax
still works but is deprecated.
Low-level Parameter Commands
There are several commands for operating on parameters of objects: <class>-param-get, <class>-param-set,
<class>-param-add, <class>-param-remove, <class>-param-clear, and <class>-param-list. Each of these takes a
uuid parameter to specify the particular object. Since these are considered low-level commands, they must be
addressed by UUID and not by the VM name label.
<class>-param-list uuid=<uuid>
Lists all of the parameters and their associated values. Unlike the class-list command, this will list the values
of "expensive" fields.
<class>-param-get uuid=<uuid> param-name=<parameter> [param-key=<key>]
Returns the value of a particular parameter. If the parameter is a map, specifying the param-key will get the
value associated with that key in the map. If param-key is not specified, or if the parameter is a set, it will
return a string representation of the set or map.
<class>-param-set uuid=<uuid> param=<value>...
Sets the value of one or more parameters.
<class>-param-add uuid=<uuid> param-name=<parameter> [<key>=<value>...] [param-key=<key>]
Adds to either a map or a set parameter. If the parameter is a map, add key/value pairs using the
<key>=<value> syntax. If the parameter is a set, add keys with the <param-key>=<key> syntax.
<class>-param-remove uuid=<uuid> param-name=<parameter> param-key=<key>
Removes either a key/value pair from a map, or a key from a set.
<class>-param-clear uuid=<uuid> param-name=<parameter>
Completely clears a set or a map.
Low-level List Commands
The <class>-list command lists the objects of type <class>. By default it will list all objects, printing a subset of the
parameters. This behavior can be modified in two ways: it can filter the objects so that it only outputs a subset,
and the parameters that are printed can be modified.
To change the parameters that are printed, the argument params should be specified as a comma-separated list
of the required parameters. For example:
xe vm-list params=name-label,other-config
Alternatively, to list all of the parameters, use the syntax:
