It tries to find a suitable QEMU binary and will use KVM if present.
We can now configure QEMU from outside with 4 variables :
- $QEMU_BIN : path to QEMU's binary
- $KERNEL_APPEND : arguments appended to kernel cmdline
- $KERNEL_BIN : path to a kernel
Default /boot/vmlinuz-$KERNEL_VER
- $INITRD : path to an initramfs
Default /boot/initramfs-${KERNEL_VER}.img
- $QEMU_SMP : number of CPU simulated by QEMU.
Default 1
(from Alexander Graf's script: http://www.spinics.net/lists/kvm/msg72389.html)
