[PATCH 00/21] qemu: Validate machine type and clean up test suite
by Peter Krempa
I was experimenting with a qemu-5.0 feature and figured out that
qemu-5.0 will drop support for machine types prior to 'pc-1.0'. What was
unexpected though is that I've figured it out as some very strange and
seemingly unrelated changes happened in the test output of the 'latest'
tests while bumping the caps data.
It turned out that the CPU driver now actually takes data from the
machine type and since the machine type was no longer present the test
data result has changed.
This lead me down a rabbit hole of trying to make our test suite more
robust and such changes easier to debug.
The result is these 21 patches that fix numerous tests, clean up some
stale and downstream machine types and in the end add validation of the
machine type and harden the testsuite to use it properly.
Note that 30k lines of the diffstat is just the qemu-5.0 capabilities
data so that we can verify that nothing changes during the capbility
upgrade.
Some of the yak-shaving done here is incomplete though as I've figured
out we have a bunch of network-device related tests which are not
enabled in the xml->argv test suite, but also are not easy to enable.
Peter Krempa (21):
tests: qemuxml2argv: Use 64 bit qemu binary and 1.5 machine type in
'disk-cache' case
tests: qemuxml2xml: Modernize 'disk-cache' test
tests: qemuxml2argv: Modernize tpm-passthrough tests
tests: qemuxml: Fix and enable default-video-type* tests

[libvirt PATCH] qemu: explicitly disable virgl when requested
by Jonathon Jongsma
If a domain is configured to have an egl-headless display and a virtio
video device, virgl will be enabled automatically within the guest, even
if the video device is configured with accel3d='no'.
In this case we should explicitly pass 'virgl=off' to qemu.
See https://bugzilla.redhat.com/show_bug.cgi?id=1791236 for more
information.

[libvirt] [PATCH v2 0/5] Support rng backend model builtin
by Han Han
https://bugzilla.redhat.com/show_bug.cgi?id=1785091
Implement 'rng-builtin' backend from QEMU. This feature is introduced
to QEMU since v4.2. It uses getrandom() to get random, no external
random source needed.
github repo: https://github.com/qiankehan/libvirt/tree/rng-builtin_v2
Changes from v1:
- Fix failures in 'make check' and 'make syntax-check'
- Adjust the structure of patches
v1:
https://www.redhat.com/archives/libvir-list/2020-January/msg00000.html

Libvirt has never produced a qemu command line containing '-snapshot'.
Part of this is that libvirt wants to control SELinux settings, and
letting qemu create a temporary overlay in /tmp in order to implement
-snapshot does not play nicely with libvirt pre-creating all files that
qemu is allowed to access.
The fact that you were able to manually add -snapshot to your qemu
command line with older libvirt using -drive (I'm assuming you were also
not using libvirt's SELinux support, because if you were, qemu would
have been unable to create/access the temporary wrapper in /tmp), is a
nice hack. But since modern qemu has declared -snapshot to be
unsupported with -blockdev, and modern libvirt has switched to
-blockdev, I claim that this is not a qemu bug, but a libvirt feature
request.
That said, libvirt has had a vision for a design for implementing the
equivalent of -drive -snapshot: the <transient/> sub-element added to
the domain/disk/source/driver element has been documented for a long time:
https://libvirt.org/formatdomain.html
"transient
If present, this indicates that changes to the device contents
should be reverted automatically when the guest exits. With some
hypervisors, marking a disk transient prevents the domain from
participating in migration or snapshots. Since 0.9.5 "
However, no one has yet implemented it for libvirt's qemu driver. Part
of our reluctance has been that we knew that implementing it would
require libvirt to precreate the wrapper file on every guest start, and
it is only very recently that we've even had enough functionality in
libvirt's qemu driver coupled with new qemu commands to create qcow2
images using QMP rather than having to shell out to qemu-img. And part
of it is that there was no point in implementing something to work with
-drive, when we knew we had to rework everything for -blockdev anyways.
But now that the work in libvirt to switch to -blockdev is done, it
should be a lot easier to implement PROPER support for the <transient/>
tag, at least for -blockdev usage.

[PATCH 0/4] qemu: fix block jobs when copy_on_read is enabled
by Peter Krempa
QEMU requires us to pass the topmost node(-name) in the backing chain as
the 'device' argument for the blockdev-mirror/block-commit commands.
Otherwise QEMU complains:
"Need a root block node"
Since libvirt always puts the copy-on-read driver on top of the backing
chain, blockjobs on disks which use "copy_on_read" fail.
The series below fixes that by passing the proper node. This fixes it
just fine for the mirror, but for block-commit we still get another
error due to a bug in qemu:
"'libvirt-4-format' is not in this backing file chain"
Additionally one weird thing happens with block-stream (blockpull). If I
pass the layer below the copy-on-read as 'device', everything works.
This is kind of weird as the documentation for that is the same. If I
pass the nodename of copy-on-read.
Max, Kevin, could you please comment on the block-stream part and
possibly also on the plans to fix the issue with block-commit?
