I am new to VM's so I wonder what is the best strategy for VM file sizing.
For example I am building a Poudiere VM and I truncated my VM for 80GB.
What if I need more later?
Can I DD my VM image into another larger image and grow the filesystem on the VM side?
So I can probably grow a VM but shrinking is not feasible?
Can't DD to a smaller target image because DD is block layer including empty space.
Not much worry. I don't need shrinking. I could see the need to grow.
