I think I didn't explain myself clearly enough while reviewing
v2: I expected patches 07-09 and 11 to be squashed together, but
patch 10 to remain standalone. No big deal, I'll take care of
splitting it up again myself.

And of course I didn't clean up the surrounding code even though I

[libvirt] [PATCH] nwfilter: Handle opening for session
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1608275
Commit id 2870419eb (in part) added virGetConnectNWFilter to
allow opening drivers (interface, network, nwfilter, nodedev,
secret, and storage) based on context and commit id f14c37ce4c
started using the API; however, the nwfilterConnectOpen did
not handle session mode resulting in the following message
being logged when virDomainConfVMNWFilterTeardown was called
during the domain shutdown processing:
error : nwfilterConnectOpen:383 : internal error: unexpected
nwfilter URI path '/session', try nwfilter:///system
So similar to the other drivers add code in to check for
/session when not privileged.

[libvirt] [PATCH] nwfilter: Add extra verbiage for binding create/delete
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1609454
Add some cautionary words related to the create and delete
NWFilter Binding use cases and possible issues that may result
to the virsh nwfilter-binding-{create|delete} descriptions
and the virNWFilterBinding{CreateXML|Delete) API descriptions.
Essentially summarizing commit 2d9318b6c without using the
shoot yourself in the foot wording.

[libvirt] [PATCH] access: Fix nwfilter-binding ACL access API name generation
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1611320
Generation of the ACL API policy is a "automated process"
based on this perl script which "worked" with the changes to
add nwfilter binding API's because they had the "nwfilter"
prefix; however, the generated output name was incorrect
based on the remote protocol algorithm which expected to
generate names such as 'nwfilter-binding.action' instead
of 'nwfilter.binding-action'.
This effectively changes src/access/org.libvirt.api.policy entries:
org.libvirt.api.nwfilter.binding-create ==>
org.libvirt.api.nwfilter-binding.create
org.libvirt.api.nwfilter.binding-delete ==>
org.libvirt.api.nwfilter-binding.delete
org.libvirt.api.nwfilter.binding-getattr ==>
org.libvirt.api.nwfilter-binding.getattr

[libvirt] [PATCH] nwfilter: Handle libvirtd restart if nwfilter binding deleted
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1607202
It's stated that if the admin wants to shoot themselves in
the foot by removing the nwfilter binding while the domain
is running we will certainly allow that. However, in doing
so we also run the risk that a libvirtd restart will cause
the domain to be shutdown, which isn't a good thing.
So add another boolean to virDomainConfNWFilterInstantiate
which allows us to recover somewhat gracefully in the event
the virNWFilterBindingCreateXML fails when we come from
qemuProcessReconnect and we determine that the filter has
been deleted. It was there at some point (it had to be), but
if it's missing, then we don't want to cause the guest to
stop running, so issue a warning and continue on.

[libvirt] [PATCH v2] qemu: qemuDomainChangeNet: validity checks should be done before XML autocompletion
by Katerina Koukiou
This patch ensures that changes in attributes of interfaces will be emit
errors accept if they are missing from the XML.
Previously we were falsely reporting successfull updates, because some
changed attributes got overwritten before the validity checks.

[libvirt] [PATCH v3 0/9] RISC-V Guest Support
by Lubomir Rintel
Hi.
Third iteration of RISC-V guest support. I believe I addressed all
points of Andrea's review. Tested with: images from [1]:
virt-install \
--import --name riscv64 \
--arch riscv64 --machine virt \
--memory 2048 \
--rng /dev/urandom \
--disk /var/lib/libvirt/images/stage4-disk.img,bus=virtio \
--boot kernel=/var/lib/libvirt/images/bbl,kernel_args="console=ttyS0 ro root=/dev/vda"
[1] https://fedorapeople.org/groups/risc-v/disk-images/
Note that the large test suite changes that touch the '*.replies' files
seem to upset the mail server, thus you're unlikely to receive them from
the list. You can get them straight from my repository instead:
git pull https://github.com/lkundrak/libvirt.git lr/riscv-v3
Changes since v2:
* Regenerated cap test data with QEMU 3.0.0
* Squashed the tests together
* Folded "docs/schemas: add RISC-V architectures" into "util: add RISC-V architectures"
* Streamlined the Virtio MMIO address assignment
* Added qemuDomainIsRISCVVirt() and qemuDomainMachineIsRISCVVirt()
* Cosmetic changes to "util: add RISC-V architectures"
* New commits:
qemu: add qemuDomainAssignVirtioMMIOAddresses()
qemu: add qemuDomainIsRISCVVirt() and qemuDomainMachineIsRISCVVirt()
qemu: RISC-V machines have no PCI
news: Add a mention of RISC-V guest support
* Dropped:
qemu: no USB by default on RISC-V machines
(not sure why I thought this was needed)
Lubomir Rintel (9):
qemu: rename qemuDomainMachineIsVirt()
qemu: rename qemuDomainArmVirt()
util: add RISC-V architectures
qemu: RISC-V machines have no PCI
qemu: add qemuDomainIsRISCVVirt() and qemuDomainMachineIsRISCVVirt()
qemu: add qemuDomainAssignVirtioMMIOAddresses()
qemu: assign addresses to virtio devices on RISC-V
tests: Add RISC-V architectures
news: Add a mention of RISC-V guest support
