Hi, since 2 days I am using KVM/QEMU to virtualize other distros. I have always used Virtualbox but lately it didn’t work anymore, I had problem after problem. So, following a tip here on the forum I moved over to KVM.
At first I thought it works faster than VBox, but now that I am watching videos on Youtube or watching TV on the website of my provider I see that the system is not that fast. I know I don’t have a top of the line computer (I’m still looking for a new one with more capacity under the hood) but still when using host Tumbleweed the videos run faster and sound and picture are synchronized, something I don’t always see in the guest (Fedora 37 btw).
This is my hardware:

I am using 6 out of 8 CPU cores and 8GB of ram. Should be enough I guess.
What I am looking for are the optimized settings I need to use for my KVM guest on the above hardware to make the guest look as fast as the host.
Which website is great for getting the right info about ow to setup the system?
