The Oracle VM Utilities include a messaging tool, which allows
sending key-value pairs to a virtual machine, or guest, and
retrieve such messages from the guest. The
vmmessage
utility requires the Oracle VM Guest
Additions to be installed on the guest side. The current edition
of Oracle VM Guest Addition includes message channel and guest IP
information. The Oracle VM Guest Additions allow direct
integration between guest software and the virtualization layer,
to assist in orchestration and automation of complex, multi-VM
deployments.
A brief description of the installation, configuration and features of Oracle VM Guest Additions can be found in Chapter 3, Using the Oracle VM Guest Additions
