Our management system uses vmchannel to communicate with an agent
running on the guest.
We use this agent to collect information about the guest OS: e.g.,
installed applications, who's logged in, whether anything's running, or
the guest is rebooting.
The agent is capable of performing operations on the guest, too. We use
this to log a user in (for single sign-on), to log a user out before
migrating to file, to renew the guest's dhcp lease if the guest is
migrated to another subnet, to name a few uses.
Dan.
