For me, it sounds like putting them on a separate service layer would be helpful, especially in highly custom environments.
I do like the thought of load-balanced system VMs. Kelcey Jamison-Damage Infrastructure Systems Architect Backbone IT Service | Backbone Datavault | Backbone Technology 55 East 7th Ave Vancouver - BC Canada V5T 1M4 kel...@bbits.ca | 604-331-1152 ext. 114 -----Original Message----- From: Edison Su [mailto:edison...@citrix.com] Sent: Wednesday, July 18, 2012 1:36 PM To: cloudstack-dev@incubator.apache.org; Kelceydamage@bbits Subject: RE: system VM out of CloudStack > -----Original Message----- > From: d...@soleks.com [mailto:d...@soleks.com] > Sent: Wednesday, July 18, 2012 10:56 AM > To: Kelceydamage@bbits > Cc: cloudstack-dev@incubator.apache.org > Subject: Re: system VM out of CloudStack > > Agree, as any changes it will create some level of complexity - but > question is - is that solution better then existing one ?

Actually, we have internally talked about to move system VMs(secondary storage vm, console proxy vm, router vm, even the API server) to a separate service layer. CloudStack core will be an Orchestration layer, with lot of extension points, and manage above service VMs, also provide essential services(VM related, such as volume/network/VM etc.) to other services. In your case, IMHO, what you really need is a separate or customized way to create SSVM, CPVM in CloudStack, either these VMs can be running on bare mental hardware, or behind a Load Balancer.
