 Hello!

=E2=9E=A2 Thank you for your comment, I might do it after solving the =
stability issues.

 What kind of stability issues do you have ?
 You know, i was testing 64-bit qemu in TCG mode, and i have also seen =
weird behavior. The kernel just stops and waits until you hit any key on =
the console, then it continues. This happens if i try to use more than =
one CPU. This has to do with guest kernel version, in v4.1rc2 this is =
gone, while still present in v4.0rc1. Originally i discovered this issue =
on v3.19. So, perhaps it's some guest kernel flaw, having to do with =
interrupts.
 The first place where it is stuck is after initializing usbcore. After =
hitting enter it says "switching clocksource to..." (i don't remember) =
and goes on. After this it can stop like this again, in some random =
moment.
 Which kernel version do you use for guest ?

Kind regards,
