Here's my response to some of the information that was missing for VM construction. Question: -For the VM project, if we use DC we need to be able to instantiate and configure the VM we are installing in. Again, likely a finalizer script but need to understand the implications of the VM project Response: I've sent out a request soliciting people's opinion on what exactly our requirements might be. I'm not convinced that we'll want to own configuring the VM from DC (at least any further than what is required to make the VM boot using the ISO we create). Question: -Need requirements for this project with regard to: VM configuration, target instantiation, target discovery, transfer of bits, post processing. Response: VM Configuration - Up in the air at this point, I know we'll need to do 'something' here but how much is up for debate. Whatever it ends up being this will likely just be a finalizer script that calls the VirtualBox cli to set up the VM, configure it to boot the ISO we're going to start the install from, start the VM and then poll the VM status to detect shutdown. What is unclear is how the finalizer script configures the VM (see my response to your question about instantiating and configuring a VM). target instantiation - We'll definitely need to come up with something for this to setup the virtual disk once we're booted inside the virtual machine. target discovery - We may or may not need to do something here. One possible approach is that the manifest we use to perform the installation inside of virtualbox specifies the name of the target disk to use. Of course that would require the 'user' to know what virtualbox is going to call the disk when booted. If we don't use that approach, then we'll need a mechanism that I suspect looks similar to what AI does. transfer of bits - currently, my design is based on issuing pkg commands and installing from a network repository (specified in the installation manifest). This could be a finalizer script. We might also leverage libtransfer but I haven't looked at that. post processing - It's not entirely clear what we'll need for this yet. There will obviously be some things we'll have to do post transfer of bits. ICT should be useful in that regard. There is also the post processing that will need to take place after installation to convert the VM into a portable OVF file. But that's merely calling the virtualbox cli to perform the necessary transform in a finalizer script. Cheers, -- Glenn
