+\section{VM boot parameters}
+
+The VM class contains a number of fields that control the way in which the VM
is booted.
+With reference to the fields defined in the VM class (see later in this
document),
+this section outlines the boot options available and the mechanisms provided
for controlling them.
+
+VM booting is controlled by setting one of the two mutually exclusive groups:
``PV'', and ``HVM''. If HVM.boot\_policy is the empty string, then paravirtual
domain building and booting will be used; otherwise the VM will be loaded as an
HVM domain, and booted using an emulated BIOS.
+
+When paravirtual booting is in use, the PV/bootloader field indicates the
bootloader to use. It may be ``pygrub'', in which case the platform's default
installation of pygrub will be used, or a full path within the control domain
to some other bootloader. The other fields, PV/kernel, PV/ramdisk, PV/args and
PV/bootloader\_args will be passed to the bootloader unmodified, and
interpretation of those fields is then specific to the bootloader itself,
including the possibility that the bootloader will ignore some or all of those
given values. Finally the paths of all bootable disks are added to the
bootloader commandline (a disk is bootable if its VBD has the bootable flag
set). There may be zero, one or many bootable disks; the bootloader decides
which disk (if any) to boot from.
+
+If the bootloader is pygrub, then the menu.lst is parsed if present in the
guest's filesystem, otherwise the specified kernel and ramdisk are used, or an
autodetected kernel is used if nothing is specified and autodetection is
possible. PV/args is appended to the kernel command line, no matter which
mechanism is used for finding the kernel.
+
+If PV/bootloader is empty but PV/kernel is specified, then the kernel and
ramdisk values will be treated as paths within the control domain. If both
PV/bootloader and PV/kernel are empty, then the behaviour is as if
PV/bootloader was specified as ``pygrub''.
+
+When using HVM booting, HVM/boot\_policy and HVM/boot\_params specify the boot
handling. Only one policy is currently defined: ``BIOS order''. In this case,
HVM/boot\_params should contain one key-value pair ``order'' = ``N'' where N is
the string that will be passed to QEMU.

+\subsection{Note on References vs UUIDs}
+
+References are opaque types --- encoded as XML-RPC strings on the wire ---
understood
+only by the particular server which generated them. Servers are free to choose
+any concrete representation they find convenient; clients should not make any
+assumptions or attempt to parse the string contents. References are not
guaranteed
+to be permanent identifiers for objects; clients should not assume that
references
+generated during one session are valid for any future session. References do
not
+allow objects to be compared for equality. Two references to the same object
are
+not guaranteed to be textually identical.
+
+UUIDs are intended to be permanent names for objects. They are
+guaranteed to be in the OSF DCE UUID presentation format (as output by {\tt
uuidgen}.
+Clients may store UUIDs on disk and use them to lookup objects in subsequent
sessions
+with the server. Clients may also test equality on objects by comparing UUID
strings.
+
+The API provides mechanisms
+for translating between UUIDs and opaque references. Each class that contains
a UUID
+field provides:
+\begin{itemize}
+\item A ``{\tt get\_by\_uuid}'' method that takes a UUID, $u$, and returns an
opaque reference
+to the server-side object that has UUID=$u$;
+\item A {\tt get\_uuid} function (a regular ``field getter'' RPC) that takes
an opaque reference,
+$r$, and returns the UUID of the server-side object that is referenced by $r$.

-VM booting is controlled by setting one of the two mutually exclusive
-groups: "PV", and "HVM". If HVM.boot\_policy is the empty string, then
-paravirtual domain building and booting will be used; otherwise the VM will
-be loaded as an HVM domain, and booted using an emulated BIOS.
-
-When paravirtual booting is in use, the PV/bootloader field indicates the
-bootloader to use. It may be "pygrub", in which case the platform's
-default installation of pygrub will be used, or a full path within the
-control domain to some other bootloader. The other fields, PV/kernel,
-PV/ramdisk, PV/args and PV/bootloader\_args will be passed to the
-bootloader unmodified, and interpretation of those fields is then specific
-to the bootloader itself, including the possibility that the bootloader
-will ignore some or all of those given values. Finally the paths of all
-bootable disks are added to the bootloader commandline (a disk is bootable
-if its VBD has the bootable flag set). There may be zero, one or many
-bootable disks; the bootloader decides which disk (if any) to boot from.
-
-If the bootloader is pygrub, then the menu.lst is parsed if present in the
-guest's filesystem, otherwise the specified kernel and ramdisk are used, or
-an autodetected kernel is used if nothing is specified and autodetection is
-possible. PV/args is appended to the kernel command line, no matter which
-mechanism is used for finding the kernel.
-
-If PV/bootloader is empty but PV/kernel is specified, then the kernel and
-ramdisk values will be treated as paths within the control domain. If both
-PV/bootloader and PV/kernel are empty, then the behaviour is as if
-PV/bootloader was specified as "pygrub".
-
-When using HVM booting, HVM/boot\_policy and HVM/boot\_params specify the
-boot handling. Only one policy is currently defined: "BIOS order". In
-this case, HVM/boot\_params should contain one key-value pair "order" = "N"
-where N is the string that will be passed to QEMU.}} \\

* The VM class.
*
* A virtual machine (or 'guest').
- *
- * VM booting is controlled by setting one of the two mutually exclusive
- * groups: "PV", and "HVM". If HVM.boot_policy is the empty string, then
- * paravirtual domain building and booting will be used; otherwise the VM will
- * be loaded as an HVM domain, and booted using an emulated BIOS.
- *
- * When paravirtual booting is in use, the PV/bootloader field indicates the
- * bootloader to use. It may be "pygrub", in which case the platform's
- * default installation of pygrub will be used, or a full path within the
- * control domain to some other bootloader. The other fields, PV/kernel,
- * PV/ramdisk, PV/args and PV/bootloader_args will be passed to the bootloader
- * unmodified, and interpretation of those fields is then specific to the
- * bootloader itself, including the possibility that the bootloader will
- * ignore some or all of those given values. Finally the paths of all bootable
- * disks are added to the bootloader commandline (a disk is bootable if its
- * VBD has the bootable flag set). There may be zero, one or many bootable
- * disks; the bootloader decides which disk (if any) to boot from.
- *
- * If the bootloader is pygrub, then the menu.lst is parsed if present in the
- * guest's filesystem, otherwise the specified kernel and ramdisk are used, or
- * an autodetected kernel is used if nothing is specified and autodetection is
- * possible. PV/args is appended to the kernel command line, no matter which
- * mechanism is used for finding the kernel.
- *
- * If PV/bootloader is empty but PV/kernel is specified, then the kernel and
- * ramdisk values will be treated as paths within the control domain. If both
- * PV/bootloader and PV/kernel are empty, then the behaviour is as if
- * PV/bootloader was specified as "pygrub".
- *
- * When using HVM booting, HVM/boot_policy and HVM/boot_params specify the
- * boot handling. Only one policy is currently defined: "BIOS order". In
- * this case, HVM/boot_params should contain one key-value pair "order" = "N"
