[libvirt] [PATCH 0/3 v3] qemu: Hotplug SCSI controllers/hostdevs
by Eric Farman 21 Nov '13

21 Nov '13

Today, hotplug of a SCSI hostdev relies on the presence of an existing SCSI controller, which can be defined in the initial domain XML. Hotplug of a SCSI controller relies on the presence of a PCI bus, which does not work in all environments. These patches correct this behavior, in order to allow hotplug (and unplug) work without incident. Changes from v2->v3: - Patch 2: Combine attach code within QEMU_CAPS_DEVICE check - Patch 2: Restructure detach to cover ..._TYPE_NONE controllers Changes from v1->v2: - Patch 2: Check for VIR_..._TYPE_NONE on controller->info.type - Patch 2: Check device address for TYPE_CCW controllers during detach - Patch 1: Fixed an indentation change that was missed Eric Farman (3): qemu: Rename controller hotplug functions to not be PCI-specific qemu: Separate calls based on controller bus type qemu: Auto-generate controller for hotplugged hostdev src/qemu/qemu_driver.c | 4 +-- src/qemu/qemu_hotplug.c | 62 +++++++++++++++++++++++++++++++++++------------ src/qemu/qemu_hotplug.h | 12 ++++----- 3 files changed, 54 insertions(+), 24 deletions(-) -- 1.7.9.5

[libvirt] [RESEND PATCH] qemu: Add support for virt machine type with virtio-mmio devices on armv7
by Clark Laughlin 20 Nov '13

20 Nov '13

These changes allow the correct virtio-blk-device and virtio-net-device devices to be used for the 'virt' machine type for armv7 rather than the PCI virtio devices.

I believe that you are seeing "Bug 956741 - When RHEL VMs are powered off/on time is off by as much as 3 hrs when system comes back up". http://libvirt.org/html/libvirt-libvirt.html#virConnectDomainEventRTCChange… says that utcoffset is relative to UTC.

[libvirt] [PATCH 00/11] enforce comma style

RHEL's rpmbuild wipes the docdir for a (sub-)package if any %doc directives are present, prior to copying in the marked documentation. This means we can't prepopulate this directory with the HTML documentation during the %install phase.
