Figure~\ref{fig-vm-lifecycle} shows the states that a VM can be in
and the API calls that can be used to move the VM between these states.
+
+\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.
