Virtualbox Memory Usage

Question

I never used virtualbox before, I have some questions on how it works. I am using windows and I want to run Linux on the VB. Does it create a partition after installation? How much phsical memory does it use? Is the memory freed after closing the VB. I bought a new laptop and the dealer said that, my warranty would be voided if I do any partition.Thanks.

1. No, VB doesn't create partition, it uses a virtual disk.
2. You can decide how much physical memory you want to assign to your virtual machine.
3. BTW I strongly recommend you reading this.
