Subject Re: [DISCUSS] Request for comments: Out-of-band Management for CloudStack (new feature)
Date Thu, 03 Mar 2016 12:58:32 GMT
Maybe I am not understanding something here.

Does this control the power cycle of the management server(s) or the
hypervisor hosts?  The wording is throwing me off.

I am guessing it is for managing the hypervisor hosts. If this is the case,
does it also handle the "maintenance mode" for the host as well? At least
with XenServer, if you do a power cycle without putting the host into
maintenance mode first, all the VRs will have to be restarted on that host
once it is back up in order for their networking to work again.

How does this fit into this?
