> Problems occur if the image.minram value it the database is set to a low
> value and a provisoning module creates a VM with too little RAM. There are
> no checks on the frontend when a new image is created. By default, images
> get set to 512 MB of RAM or less.
> This can obviously cause VMs to fail to boot and slow running VMs if the boot
> succeeds. Another side effect is failed image captures. A VM may be able to
> boot with too little RAM due to the pagefile being used. When an image is
> captured, the pagefile is disabled and the VM is rebooted. The image capture
> may fail because the VM has trouble booting without a pagefile.
> The VMware.pm module has code to prevent this, but the minimum RAM values are
> hard-coded in this module which isn't ideal.
> It would be better if the provisioning module had a way to query either the
> OS module or the OS table in the database for a more appropriate value.
> There are tradeoffs for each method.
> Storing the values in the database allows the values to be easily adjusted.
> The difficulty would be having to add additional entries for multiple
> architectures such as win7-32bit and win7-64bit. I'd rather not do this
> until the OS table is redesigned. The OS table is already a horrible mess.
> See https://issues.apache.org/jira/browse/VCL-566
> Having each OS module provide a get_minimum_ram subroutine is another option.
> This means hard-coding the values but would allow the OS module to logically
> figure out the minimum RAM. I think this is a better approach until the OS
> table is fixed.
