Process priority selectable...

The user should be able to set the process priority directly in the GUI :)

Sorry, but I don't see why you can't use an external tool for that. Putting many (unnecessary) features in the GUI will make it hard to use.

I think VirtualBox should provide the option to set the process priority so that you can choose to run every VirtualBox process by default with a low/high priority.

Also it'd be neat if VirtualBox could provide the option to automatically bump the priority a little bit when a guest has the keyboard/mouse focus.

@sandervl73: Your argument about using an external tool is good, but I think there is no tool that allows such things as described above.

There are external tools for adjusting (or pre-setting) the process priority. For Windows check the Sysinternals tools (on the Microsoft website).

vmware has an option to change the process priority for guests, both for their focused and un-focused states. While I dont care much about changing the priority for guest's un-focused state, which is also possible with external tools, I believe changing the process priority for the focused state is an important addition.

1- This is not possible with external tools. 2- This is not an unnecessary feature. 3- The argument about putting the feature in the GUI would make it hard to use is just plain weak.

[Gabriel Cossette]

I agree, this feature would be very useful!

Please consider it :)

Since it's impossible to adjust priority with external tools (such as by hand), could you make this feature 'happen'?

Just add a global setting, and a per-guest one, for Windows.
That's it. Virtualbox just kills my computer once CPU usage reaches 100%.

Please add process priority as a VM setting. Applications for desktop computers should be well behaved, and VirtualBox is the only user app i've ever seen that doesn't let you set its process priority in any way. CPU cap is not a solution, like Windows 3.11/MS-DOS is not an OS.

Changing the priority of VirtualBoxVM.exe is met with access denied in Windows 10. Would be handy to be able to set priority within VirtualBox to avoid difficulty trying to do it externally. Since new update to make VirtualBox Windows 11 friendly is currently in the works perhaps now would be a good time to revisit this?
