Nest VT-x/AMD-V doesn't seem to be turned on in the VM but in the laptop bios Intel VT-d feature and virtualization are both enabled. Has anyone else have issues lately with virtual box regarding slow vms?ĮDIT: I am using Windows 10 with the latest updates as my host, Windows 10 with latest updates as guest, Virtual box 6.1.32 r 149290 (It ran fine when it was 6.0). Have there been any new virtual box or windows 10 updates that could have caused this big increase in slowness on my machine? I have already checked if my active time on task manager was the issue, but the device seems to have fully restarted. I can click anywhere and things do load but it feels, "fragile". Installing additions does helps a little but not massively. I have also looked at my laptops power settings, plugged in the charger, removed and reinstalled virtual box but nothing has helped. So i think its either a Windows update that messed things up or Virtual box. There i can run multiple vms without problems. The weird thing is with other Virtualization software like VMware workstation there are no slowdown issues. The task bar had a clear blue colour and nothing was responding. It seems for me that vboxsvga creates a lot of issues.

I noticed the setting of the videocontroller would revert to vboxsvga when i turned on the 3d settings. I created a new Windows 10 VM, standard settings 4gb ram, 3d on, 256mb videoram, still slow.

I could run over 3 virtual machines at the same time and there were no slowdown problems. It used to run Windows Server 2016, Windows 10, etc fine.

I know its not the newest of the newest laptops but up until a few weeks ago running Windows 10 in vms was normal. Specifications are a i7-3840QM, 32gb DDR3 1866mhz ram, 2x500gb ssds, 1tb hdd. I have a Thinkpad W530 with Windows 10 and the latest Windows Updates.
