[PATCH 00/10] PCI passthrough support for ch guests
by Praveen K Paladugu
This patch series introduces PCI passthrough support for ch guests. While
enabling this feature I refactored a bunch of methods from qemu to hypervisor
to reduce duplication of logic between the drivers.
Praveen K Paladugu (7):
hypervisor: move HostdevNeedsVFIO to hypervisor
hypervisor: move HostdevHostSupportsPassthroughVFIO
qemu: replace qemuHostdevPreparePCIDevices
ch: prepare domain definition for pci passthrough
ch: allow hostdev in domain definitions
ch: reattach PCI devices to host while stopping guest
ch: explicitly set INFILESIZE to 0
Wei Liu (3):
ch: add host device manager to driver
ch: add scaffolding for host devices management
ch: prepare host for PCI passthrough

[PATCH 00/19] hw/microblaze: Allow running cross-endian vCPUs
by Philippe Mathieu-Daudé
Make machines endianness-agnostic, allowing to run a big-endian vCPU
on the little-endian 'qemu-system-microblazeel' binary, and a little
endian one on the big-endian 'qemu-system-microblaze' binary.
Tests added, following combinations covered:
- little-endian vCPU using little-endian binary (in-tree)
- little-endian vCPU using big-endian binary (new)
- big-endian vCPU using little-endian binary (new)
- big-endian vCPU using big-endian binary (in-tree)
Deprecate untested big-endian machines, likely build on the big
endian binary by mistake:
- petalogix-ml605
- xlnx-zynqmp-pmu
To make a target endian-agnostic we need to remove the MO_TE uses.
In order to do that, we propagate the MemOp from earlier in the
call stack, or we extract it from the vCPU env (on MicroBlaze the
CPU endianness is exposed by the 'ENDI' bit).
Note, since vCPU can run in any endianness, the
MemoryRegionOps::endianness should not be DEVICE_NATIVE_ENDIAN
anymore, because this definition expand to the binary endianness,
swapping data regardless how the vcpu access it.
See adjust_endianness() -> devend_memop(). Something to keep in
mind, possibly requiring further work and optimizations (avoid
double-swap).
Next step: Look at unifying binaries.
Please review,
Phil.

[PATCH v3 0/5] ch: handle events from cloud-hypervisor
by Purna Pavan Chandra Aekkaladevi
changes from v2->v3:
* Remove patch 'utils: Implement virFileIsNamedPipe' as it is no more needed.
* Remove the eventmonitorpath only if it exists
* Added domain name as a prefix to logs from ch_events.c. This will make
debugging easier.
* Simplified event parsing logic by reserving a byte for null char.
changes from v1->v2:
* Rebase on latest master
* Use /* */ for comments
* Remove fifo file if already exists
* Address other comments from Praveen Paladugu
cloud-hypervisor raises various events, including VM lifecylce operations
such as boot, shutdown, pause, resume, etc. Libvirt will now read these
events and take the necessary actions, such as correctly updating the
domain state. A FIFO file is passed to `--event-monitor` option of
cloud-hypervisor. Libvirt creates a new thread that acts as the reader
of the fifo file and continuously monitors for new events. Currently,
shutdown events are handled by updating the domain state appropriately.
Purna Pavan Chandra Aekkaladevi (5):
ch: pass --event-monitor option to cloud-hypervisor
ch: start a new thread for handling ch events
ch: events: Read and parse cloud-hypervisor events
ch: events: facilitate lifecycle events handling

[PATCH v2 0/4] fix AppArmor policy restore for runtime rules
by Georgia Garcia
Some rules are generated dynamically during boot and added to the
AppArmor policy. An example of that is macvtap devices that call the
AppArmorSetFDLabel hook to add a rule for the tap device path.
Since this information is dynamic, it is not available in the xml
config, therefore whenever a "Restore" hook is called, the entire
profile is regenerated by virt-aa-helper based only the information
from the VM definition, so the dynamic/runtime information is lost.
This patchset fixes that by storing these rules in a different file
called libvirt-uuid.runtime_files, which is included by
libvirt-uuid.files that already exists. It also includes other fixes
like memory leaks, adoption of the GLib API in the apparmor files and
a fix on the AppArmor policy that incorrectly applies apparmor policy
syntax.
Georgia Garcia (4):
security_apparmor: fix memleaks in AppArmorSetFDLabel
security: replace uses of label and VIR_FREE by g_autofree
apparmor: fix UUID specification
virt-aa-helper: store dynamically generated rules

[PATCH] qemu: Move PostParse functions out of qemu_domain.c
by Michal Privoznik
Problem with qemu_domain.c is that it's constantly growing. But
there are few options for improvement. For instance, validation
functions were moved out and now live in qemu_validate.c. We can
do the same for PostParse functions, though since PostParse may
modify domain definition, some functions need to be exported from
qemu_domain.c.
