Dear Nil,<br>
<br>
The Barrelfish build system builds a multiboot image which should be<br>
directly bootable in grub. Have you checked out the documentation?<br>
<br>
Barrelfish will boot on as many cores as it can see or that you tell<br>
it (with a kernel command line option), but Qemu is only capable of<br>
using a single physical core. If you want to explore multicore issues<br>
properly, though, you really need to boot Barrelfish on real hardware<br>
or a cycle-accurate simulator like GEM5.<br>
