[occi-wg] OCCI MC - State Machine Diagram

[Michael Richardson]

Missing are error states.

For instance, "starting" may well lead to an error state such as "failed
to boot".  The VM may well be spinning cycles at "Kernel panic", "db>",
or "Failure on Drive C, abort,retry,fail".  The failed state is
important for clients to know, and possibly also for billing.

Another state that I can think of that might be important is network 
disconnect --- you may have a VM that is ACTIVE, but the networks are
disconnected. I'd call this state "STANDBY"

(Or not yet connected).   I often do this in my virtualized
infrastructure: bring up a VM with a new version of software, on a new
IP, with VRRP/CARP configured, but I'm not going to connect it on the
live side until it's confirmed to be up, at which point, I enable the
networking, and it takes over the virtual IP.
