Subject: Heads up: Introduction of new xVM SMF milestone

You can safely ignore this message if you don't use the xVM hypervisor on
x86 systems.

The putback of:

6885672  Provide hypervisor configuration panel and associated service

introduces a new SMF milestone, svc:/milestone/xvm, which can be used to
conveniently enable/disable the xVM hypervisor. There is no need to use
the existing xVM services if this milestone is used.

To enable the hypervisor:

svcadm enable svc:/milestone/xvm

This will use bootadm(1M) to convert an existing menu.lst entry so that
on next reboot the hypervisor will be started. The store service,
svc:/system/xvm/store, goes into maintenance to indicate that a reboot is
required.

To disable the hypervisor:

svcadm disable svc:/milestone/xvm

This will use bootadm(1M) to convert an existing menu.lst entry so that
on next reboot Solaris will start on hardware.

Please be aware that using this service will result in any tweaked parameters
being discarded. In addition, the service will install a default value for
the dom0_mem property (half of system memory or 2048MB, whichever value
is lower).

It is still possible to manually edit the menu.lst file, however use of the
service will discard your changes.
