We had the discussion on the inclusion of an error state and it versus an error exit and it was agreed that an error exit would be used.

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. -- ] Y'avait une poule de jammé dans l'muffler!!!!!!!!! | firewalls [ ] Michael Richardson, Sandelman Software Works, Ottawa, ON |net architect[ ] mcr@sandelman.ottawa.on.ca http://www.sandelman.ottawa.on.ca/ |device driver[ ] panic("Just another Debian GNU/Linux using, kernel hacking, security guy"); [ _______________________________________________ occi-wg mailing list occi-wg@ogf.org http://www.ogf.org/mailman/listinfo/occi-wg ------------------------------------------------------------- Intel Ireland Limited (Branch) Collinstown Industrial Park, Leixlip, County Kildare, Ireland Registered Number: E902934 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
