Re: [libvirt] [PATCH v3] qemu: don't use deprecated -no-kvm-pit-reinjection

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 --- v3: use -global instead of trying to add another -device re: https://www.redhat.com/archives/libvir-list/2013-July/msg00833.html Unsetting the QEMU_CAPS_NO_KVM_PIT capability for QEMU >1.2 seems to work okay with libvirtd upgrades. v2: https://www.redhat.com/archives/libvir-list/2013-July/msg00821.html v1: https://www.redhat.com/archives/libvir-list/2013-July/msg00045.html src/qemu/qemu_capabilities.c | 5 ++-- src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 8 ++++-- .../qemuxml2argv-kvm-pit-delay.args | 5 ++++ .../qemuxml2argv-kvm-pit-delay.xml | 29 ++++++++++++++++++++++ .../qemuxml2argv-kvm-pit-device.args | 5 ++++ .../qemuxml2argv-kvm-pit-device.xml | 29 ++++++++++++++++++++++ tests/qemuxml2argvtest.c | 4 +++ 8 files changed, 82 insertions(+), 4 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-kvm-pit-delay.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-kvm-pit-delay.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-kvm-pit-device.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-kvm-pit-device.xml diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index dc8f0be..06b71b5 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -242,6 +242,7 @@ VIR_ENUM_IMPL(virQEMUCaps, QEMU_CAPS_LAST, "usb-storage.removable", "virtio-mmio", "ich9-intel-hda", + "kvm-pit", ); struct _virQEMUCaps { @@ -1393,6 +1394,7 @@ struct virQEMUCapsStringFlags virQEMUCapsObjectTypes[] = { { "usb-storage", QEMU_CAPS_DEVICE_USB_STORAGE }, { "virtio-mmio", QEMU_CAPS_DEVICE_VIRTIO_MMIO }, { "ich9-intel-hda", QEMU_CAPS_DEVICE_ICH9_INTEL_HDA }, + { "kvm-pit", QEMU_CAPS_DEVICE_KVM_PIT }, };
