[PATCH 0/6] ch: handle events from cloud-hypervisor
by Purna Pavan Chandra Aekkaladevi
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 (6):
utils: Implement virFileIsNamedPipe
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

[PATCH] (for 10.8.0? undecided) qemu: fix regression in update-device for interfaces
by Laine Stump
Commit a37bd2a15b8f2e7aa09519c86fe1ba1e59ce113f eliminated a failure
to update *any* change in an interface that was connected via a
network that consisted of a pool of VFs using macvtap passthrough
mode. Unfortunately it caused a regression that results in failure to
update changes to bandwidth/vlan/trustGuestRxFilters in any interface
connected via a network that uses a bridge to connect tap devices.
This fixes that problem by narrowing the usage of the fix in the
earlier patch to only be done in the case that the the interface is
connected via a macvtap+passthrough network.
Signed-off-by: Laine Stump <laine(a)redhat.com>
Fixes: a37bd2a15b8f2e7aa09519c86fe1ba1e59ce113f
---
The alternatives to this are:
1) revert a37bd2a15b8f2e7aa09519c86fe1ba1e59ce113f (but I haven't
checked yet if that will cause problems with the other patches in
that same series) to eliminate the regression but also unfix the
bug that was fixed, or
2) Do nothing and release with the regression.
Wish I'd found this a couple days earlier :-/
