[PATCH v4] qemu: don't use deprecated -no-kvm-pit-reinjection

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since qemu-kvm 1.1 [1] (since 1.3. in upstream QEMU [2])
'-no-kvm-pit-reinjection' has been deprecated.
Use -global kvm-pit.lost_tick_policy=discard instead.

https://bugzilla.redhat.com/show_bug.cgi?id=978719

[1] http://git.kernel.org/cgit/virt/kvm/qemu-kvm.git/commit/?id=4e4fa39
[2] http://git.qemu.org/?p=qemu.git;a=commitdiff;h=c21fb4f
---

v4: check for the property of the kvm-pit device instead of just the
kvm-pit device
keep the NO_KVM_PIT capability
v3: use -global instead of trying to add another -device
v2: https://www.redhat.com/archives/libvir-list/2013-July/msg00821.html
v1: https://www.redhat.com/archives/libvir-list/2013-July/msg00045.html
