Activating virtualization reduces the usable ram

Question

I have 8GB of RAM and when I enable virtualization the usable RAM drops from 7.90GB to 5.93GB. I thought it was due to the RAM allocated for the video, but between Bios I set it to the minimum, which is 64 MB, but the problem still continues. Another thing that happens is that when I activate virtualization by itself, the monitors do not give me an image and do not start the system, so I have to start I have to activate a separate option in the BIOS called (nvme raid mode) that I don't know exactly what it does, but at least it allows me to start the system. In case I have something to do, it is worth mentioning that I have an AMD processor with integrated graphics card and I also have a dedicated one from NVIDIA, regarding this I have configured two monitors, one with integrated graphics and the other with the dedicated card I think this has something to do with it since I think reserved RAM is assigned to the integrated graphics card. ![15392-image.png][1] ![15391-image.png][2] En la imagen de abajo se ve que la esta utilizando la targeta integrada.

Answer 1

Host is going to need a minimum of 2 gB of ram to run the host OS, 8gB ram total is really not sufficient to run much. You can probably run one virtual machine guest. I'd recommend adding some ram if possible.

Answer 2

Hi Diego，
The nvme raid mode would enable you setup raid on nvme SSDs. Don't know if you have the OS installed on a raid volume.
Do you mean enable the AMD-V in BIOS or turn on Hyper-V feature in Windows when you say “activating virtualization”?

As this could be a hardware issue, I suggest you post on some hardware forum or contact your motherboard vendor for BIOS update, memory compati, etc.
Best Regards
