Thanks Kevin. This was the answer I expected, so here follows my second question:I think the state of the art is to give the VMs enough memory rather
By increasing virtual RAM, I'm afraid that the guest OS may detect and use more memory, causing the host to pay the price of overcommited memory being swapped on the host. If the guest OS (let's say Linux) detects less available memory, isn't there a chance it will try to use less memory? My guess is that the OS's should distinguish between physical (fast) and swap memory (slow) for better memory management.
Any thoughts?
