Hi everybody. I'm writing concerning an issue on my VirtualBox. I'm running Win10 as guest using Linux Debian 9 as host on a VirtualBox 6.1. It is running on a desk computer with 16 Gb of RAM and a Intel i7-4770k. The problem is that when I start the Win10 the host CPU usage goes to almost 100% and, as expected, the temperature of the processor goes up approaching to +100 degrees. This increment is more noticeable after logging in. According to Task Manager, on idle Win10 is using around 40% of the available CPU.
I read several topics by people with similar issues, but none of the possible solutions worked for me.
I'm attaching a VirtualBox log obtained starting the VM from cool-boot and then shutting down.
Thanks in advance.

Re: 100% CPU usage on host
Only two cores are assigned to the VM, so it can't be the VM which is maxing out all cores on the host.
Looking at the log I see that 3D acceleration is not enabled: software rendering will definitely slow things down.

However I'm not sure whether this indicates what we already know - that 3D acceleration is not enabled, or whether it indicates a weak graphics driver on the host.00:00:08.300856 VMMDev: Guest Log: VBoxMP::DriverEntry: WDDM: 3D is not supported, hardware type 1
