[Qemu-devel] [PATCH 21/28] Use global properties to emulate -no-kvm-pit-reinjection

[Marcelo Tosatti]

From: Jan Kiszka <address@hidden>

Releases of qemu-kvm will be interrupted at qemu 1.3.0.
Users should switch to plain qemu releases.
To avoid breaking scenarios which are setup with command line
options specific to qemu-kvm, port these switches from qemu-kvm
to qemu.git.

Port -no-kvm-pit-reinjection.
