This is a qemu 5.0 bug with ryzen. Try changing from host-passthrough to host-model in your xml. There is another way to fix this bug it requires some qemu args added to the end of your xml but I'm not at home to give them to you but they work for sure.

@ernestp I had the same issue caused by Kaspersky Internet Security installed inside the VM. By default KIS checks if any virtualisation features are available and try's to use it. Any time i tried to change some settings in KIS or even uninstalling it, it will crash the VM. I couldn't even dissable this function. Changing it to "host-model" or to "custom" allowed me to dissable this feature in Kaspersky. I guess for you there are features like Hyper-V enabled which sees some CPU features from the host system and tries to use them. Try to dissable Hyper-V if you don't need them or use the "custom"  or "host-model" cpu flag.
