just played lords of the fallen which uses easy anti-cheat. It detected my vm until i applied these changes from the comment of shakinbacon: under <os> put <smbios mode='host'/> directly below that put this under <features> <kvm> <hidden state='on'/> </kvm> under <cpu mode ='host-passthrough'....... put <feature policy='disable' name='hypervisor'/> After these changes the game worked, but performance was terrible (more than halved my framerate). I applied changes individually and learned this: only kvm hidden state = on meant my machine was still detected. only <smbios mode='host'/> allowed me to run my game and it didnt affect my performance. tl;dr apply all 3 of the changes above to try to hide your virtual machine. Then, if you notice a performance hit, apply the changes one by one until you found the one that hides your vm while maintaining performance
