make 2 vms share everything

I would like to make a VM that has 2 "modes": a "machine" mode where the VM has access to more cores and ram, and an "app" mode that limits the amount of ram and cores the VM can use. So far, I have accomplished this through makeing a machine VM with 4 cores and 8GB of ram, and an app vm with 2 cores and 2 GB of ram. However, to prevent corruption, I have to shut down the VM everytime I wish to switch modes. Is there a way I can have the 2 vms share snapshots and suspend states?

 

Hi, and how about installing 2 virtual machine? Would you like to use 1 VM for 2 modes, am I right?

 

yes, but installing 2 separate VMs would have separate .HDDs, snapshots, and suspends.

 

Thank you for your reply.
Could you share with us how do you use your VM for now please? (Step-by-step instructions will be very helpful)
