4. Technical Description
SMF services for Xen addendum
1. Introduction
PSARC 2007/127 introduced the new SMF services provided for running a
Solaris-based domain 0 when running on Xen or a Xen-compatible hypervisor.
Further work has generated the need for an additional service, described
below. The "platform profiles" problem described in PSARC 2007/127 applies
equally well to this service.
As before, a patch binding is requested.
2. Domains service
Solaris zones provides a simple transient service that allows autobooting
of zones when the control plane (global zone) is booted, and graceful
shutdown at shutdown/reboot time. In a similar fashion this amendment is
for the transient service:
svc:/system/xctl/domains:default
Behaviour is very similar to that of system/zones:default; guest domains
marked as autoboot are booted at dom0 boot time, and are shut down cleanly
at shutdown.
This is achieved by having the 'domains' service depend upon xend:default.
When the service is started, we ask xend to autoboot all domains as needed.
On shutdown, we ask xend to shutdown all running domains and wait for this
to complete (timing out after 6 minutes if no further progress is being
made).
Note that a restart of xend should not cause guest domains to be restarted.
This is the current behaviour of the upstream community version of Xen. We
have avoided this behaviour by making sure the domains service does not
restart on a restart of its dependent services, xend and xenconsoled.
We intend to work with the community to fix this defect in the upstream
version in a similar fashion.
3. Interface table
It is unclear that the interfaces provided in this document will remain
stable as upstream community development continues. In particular,
forthcoming releases are providing a radical new base for administrative
remote access to the control tools. As a result, we feel that the
interfaces described here are best represented by a classification of
Volatile:
svc:/system/xctl/domains:default Volatile
