Several questions about configuring vApps.

anon11 · ‎03-25-2010

Hello, I have some questions about vApps coniguration:

Does vCloud API provide possibility of reconfiguring vApp entity? E.g. adding memory to running application?

Is there possibility to instantiate AppTemplate on specific resources (procs, memory)? As far as I see resource requirements are stored inside AppTemplate and cannot be changed without creating another appTemplate, are they?

As of version 0.8, I don't see a way to change the resource (cpu, mem) allocation of a running vApp with vCloud API.

You can change the resources by specifying the VirtualHardwareSection as described on page 33-34 of the following doc. You don't need yet another template for a new configuration.

Thank you for response.

>As of version 0.8, I don't see a way to change the resource (cpu, mem) allocation of a running vApp with vCloud API.

So what are the chances of appearing this feature in next versions of vCloud API?

Good question. I don't know. You may want to contact VMware product management for the answer.
