I am running a single instance of Debian in kvm and have allocated 4 cores and 4G ram. However, when I play a video in the browser, almost all the cpu activity seems to get allocated to a single core and overloads it. This then puts my machine into stress mode. Is there a way to spread the load over several cores? Can gpu help with video playback? I have plenty of resources but they are not being used correctly. See below for more info:
