The actual state of my machine: os: Window 10 64bit CPU: i5-6400 ram: 32GB GPU: GTX 1050 Nvidia Dual monitor 4K
I installed last VirtualBox 6.0.4 and I installed Debian 9.6 on the VM.
VM state: core: 4 ram: 10GB gpu ram: 256MB enalbe: VT-x/AMD-V dual monitor enabled
I installed virtual-guest-addition with all required packages properly but my VM run very very slow.
I can't understand why because it runs with an average consumption of resources.
I think only to the dual monitor 4k, I can't think of anything else. Unfortunately, this system is unusable.
