I noticed that if I enable IO-APIC in the VM settings (under "System") the
4.8.4 kernel works, if it's disabled it immediately reboots after the kernel is
loaded.
Maybe this helps in finding the problem?

Also I noticed when booting the LiveCD that this message shortly is displayed
after the kernel is loaded, before the system reboots:
"Probing EDD (edd=off to disable)... OK"
(I don't see that message when booting the Tumbleweed installation)
edd=off doesn't help though (it only makes this message disappear).
