Hello there! So I have a quick Q regarding creation of new virtual machines with Vmware. Since this is my first time please be kind I am trying to create around 3-4 virtual machines with Vmware but I got a few Qs: - Each new virtual machine will eat some of my RAM only when I "Power on" that machine or even when I have it "Turned off"? - Do I have to install an operating system each time I create a new virtual machine or can I somehow use the one already installed in my PC? Just these two for now.. Thank you!
