Starting a QEMU instance manually configured to boot a Fedora installation
kernel with the -kernel/-initrd command-line options cause ACPI to brake
in the guest with the following messages:

[ 0.148843] ACPI: Interpreter disabled
As the ACPI support in the guest kernel is not functional, QEMU won't be
notified when the guest is powered off by the user which in turn won't
cause QEMU to emit QMP events and change the RunState from "running" to
"paused". This in turn cause problems to libvirt too.
I bisected this and the culprit is:
commit 868270f23d8db2cce83e4f082fe75e8625a5fbf9
Author: Michael S. Tsirkin <mst@redhat.com>
Date: Mon Jul 28 23:07:11 2014 +0200
acpi-build: tweak acpi migration limits
Indeed, if I revert that commit everything works as expected.
Here is my full reproducer. Please, note that I didn't cook that reproducer
myself. This problem was originally reported as a libvirt/QMP problem.
1. Download initrd.img and vmlinuz from a fedora mirror (eg. http://fedora.mirror.lstn.net/releases/20/Fedora/x86_64/os/images/pxeboot/)
2. Run QEMU with:
# qemu -enable-kvm -m 1024 -no-shutdown \
-boot strict=on -kernel /home/lcapitulino/files/vmlinuz \
-initrd /home/lcapitulino/files/initrd.img \
-append method=http://fedora.mirror.lstn.net/releases/20/Fedora/x86_64/os/ \
-drive file=/var/lib/libvirt/images/rhel7.img,if=virtio \
-monitor stdio -vnc :0 -qmp tcp:0:4444,nowait,server
3. After the kernel boots, switch to to the installer shell:
(qemu) sendkey ctrl-alt-f2
4. Check if the kernel's ACPI interpreter has been enabled
# dmesg | grep -i interpreter

Thanks.
Please try
[PATCH] pc: reserve more memory for ACPI for new machine types
that I just sent.
