[libvirt] [PATCH] util: Fix a bug in virResctrlMonitorGetStats
by Wang Huaqiang
The path argument of virFileIsDir should be a full name
of file, pathname and filename. Fixed it by passing the
full path name to virFileIsDir.

[libvirt] [libvirt-python PATCH] Fix copy paste error on the version check value
by John Ferlan
Signed-off-by: John Ferlan <jferlan(a)redhat.com>
---
This one I'll push under the build/test breaker rule...
I hadn't "installed" the libvirt library with the API so when "testing"
the build I just removed the CHECK_VERSION lines... Of course when looking
at the CI results I still saw the fail... So I looked more closely and saw
the errors of my ways, <sigh>... Before pushing this, I did install the
libvirt API/library changes on my host and rebuilt "naturally" and got a
pass, so I sincerely hope I got this right for the CI test env.!

[libvirt] [PATCH v2 0/2] Couple of fixes and impl for virDomainSetIOThreadParams
by John Ferlan
v1: https://www.redhat.com/archives/libvir-list/2018-November/msg00772.html
Changes since v1:
- Pushed the first two patches w/ R-By
- Add/Insert a patch to handle when PyDict_Check fails
- Modify libvirt_virDomainSetIOThreadParams from code review for
the @args on the same line (not sure why I did that) and to add
the else for PyDict_Check failure with error message.
- Change the "IOThread performance parameters" to "IOThread polling
parameters" since that more closely describes them.

[libvirt] [PATCH 00/13] Add hvf domain type for Hypervisor.framework
by Roman Bolshakov
Hypervisor.framework provides a lightweight interface to run a virtual
cpu on macOS without the need to install third-party kernel
extensions (KEXTs).
It's supported on machines with Intel VT-x feature set that includes
Extended Page Tables (EPT) and Unrestricted Mode since macOS 10.10.
QEMU supports Hypervisor.framework since 2.12.
Roman Bolshakov (13):
conf: Define hvf domain type
qemu: Define hvf capability
qemu: Query hvf capability on macOS
qemu: Expose hvf domain type if hvf is supported
qemu: Rename kvmCPU to accelCPU
qemu: Introduce virQEMUCapsTypeIsAccelerated
qemu: Introduce virQEMUCapsHaveAccel
qemu: Introduce virQEMUCapsToVirtType
qemu: Introduce virQEMUCapsAccelStr
qemu: Make error message accel-agnostic
qemu: Correct CPU capabilities probing for hvf
schema: Add hvf domain type
news: Mention hvf domain type
