Summary: QEMU (0.12.2) startup problem with kvm and flag -no-reboot

Initial Comment:
Problem description:
---------------------------------------
QEMU (0.12.2) does not startup (not even one output message is displayed e.g. from BIOS boot etc.) if flag "-no-reboot" and kvm support is enabled. QEMU immediately quits if the following startup configuration is used.

QEMU:
qemu-0.12.2 (or qemu-kvm-0.12.2) 
(Note: qemu-kvm-0.11.1 is working fine)

Not working anymore case:
[]$ qemu-system-x86_64 -kernel bzImage -initrd rootfs.cpio.gz -no-reboot -no-kvm-pit -enable-kvm
[]$ qemu-system-x86_64 -kernel bzImage -initrd rootfs.cpio.gz -no-reboot -no-kvm-pit -no-kvm-irqchip -enable-kvm
[]$ qemu-system-x86_64 -kernel bzImage -initrd rootfs.cpio.gz -no-reboot -no-kvm-irqchip -enable-kvm

Working case:
[]$ qemu-system-x86_64 -kernel bzImage -initrd rootfs.cpio.gz -no-reboot -no-kvm-pit -no-kvm
[]$ qemu-system-x86_64 -kernel bzImage -initrd rootfs.cpio.gz -no-reboot -no-kvm-pit -no-kvm-irqchip -no-kvm
[]$ qemu-system-x86_64 -kernel bzImage -initrd rootfs.cpio.gz -no-reboot -no-kvm-irqchip -no-kvm
