[libvirt] [jenkins-ci PATCH] guests: Allow ssh access as user regardless of flavor
by Andrea Bolognani
We already allow the host user to ssh into guests as root
using key-based authentication, so it makes no sense to
prevent them to ssh in as the regular user.

[libvirt] [RFC v2 00/16] Add vhost-user-gpu support
by marcandre.lureau＠redhat.com
From: Marc-André Lureau <marcandre.lureau(a)redhat.com>
Hi,
This series of patches add support for running a virtio GPU in a
seperate process, using vhost-user.
The QEMU series "[PATCH v4 00/29] vhost-user for input & GPU" is still
under review, and will hopefully land in 3.1. There are several
benefits of running the GPU process in an external process, since Mesa
is rather heavy on the qemu main loop, and may block for a while or
crash. I observe x5 performance improvements with Unigine Heaven 4
benchmark.
The external GPU process is started with one end of the vhost-user
socket pair, the other end is given to a QEMU chardev. It is also
added to the emulator cgroup to restrict its CPU usage.
vhost-user requires shared VM memory. The first patches ease and
improve shared memory setup, by using memfd. They could be considered
seperatly, but that's the setup I'd recommend with vhost-user-gpu.
Review welcome!
RFCv2:
- add new memfd memroyBacking source type
- drop the implicit shared memory NUMA setup approach, explicit now
required
- rebased
Marc-André Lureau (16):
qemu: add memory-backend-memfd capability check
qemu: add memfd memory backing
qemu: add vhost-user-gpu capabilities checks
domain: add "vhost-user" video type
qemu: fill the vhost-user video type capability
qemu: check that qemu is vhost-user-vga capable
qemu: vhost-user is valid as non-primary video device
qemu: validate vhost-user video model
qemu: add qemuSecurityStartVhostUserGPU helper
qemu: add vhost-user-gpu helper unit
qemu: restrict 'virgl=' option to 'virtio' video type
qemu: set default address type on vhost-user video model
qemu: start/stop the vhost-user-gpu external device
qemu: build vhost-user-backend for vhost-user-gpu
qemu: build vhost-user-gpu video device arguments
tests: add vhost-user-gpu xml2argv tests

[libvirt] [PATCH 00/22] syntax-check: Check misaligned stuff and fix them (batch II)
by Shi Lei
This series is batch(II) and it continues to fix misaligned arguments and misaligned
conditions in src directory. The batch I:
https://www.redhat.com/archives/libvir-list/2018-September/msg00888.html
In addition to fix misaligned stuff, this series includes several other jobs:
==========================================
1. Relax the checking-rule for misaligned.
==========================================
In addition to the check-rule in batch I, a new code style is okay:
Linefeed can be put behind the open-parenthesis of the function,
the position of argument should be:
1) pos % 4 == 0
2) pos > start_of_function_name(includes func's parent_pointer)
3) pos is the first place which matches 1) and 2)
E.g.
[indent]if (virLongLongLongFunctionName(
[4-spaces-align]LongLongLongFirstName,
[4-spaces-align]LongLongLongSecondName) < 0)
or
[indent]ret = pointer->virFunctionName(
[4-spaces-align]LongLongLongFirstName,
[4-spaces-align]LongLongLongSecondName);
====================================================
2. Add indicator to help correcting misaligned stuff.
====================================================
The [patch 21/22] definitely indicates the correct position.
===========================================
3. Improve the speed of check-spacing.pl .
===========================================
The [patch 22/22] uses global var, rather than passing arguments
to subroutine. It can be a bit faster.
The benchmark for check-spacing.pl on my PC:
(before batch I ) 1.6s
(before batch II ) 3.3s
(apply this patch) 2.7s
====================================================
# Remaining work after this batch. (for src directory)
====================================================

[libvirt] domain XML for tracking libosinfo ID
by Cole Robinson
Right now in virt-manager we only track a VM's OS name (win10, fedora28,
etc.) during the VM install phase. This piece of data is important
post-install though: if the user adds a new disk to the VM later, we
want to be able to ask libosinfo about what devices the installed OS
supports, so we can set optimal defaults, like enabling virtio.
There isn't any standard libvirt XML field to track this kind of info
though, so apps have to invent their own schema. nova and rhev do it
indirectly AFAICT. gnome-boxes does it directly with XML like this:
<metadata>
<boxes:gnome-boxes xmlns:boxes="https://wiki.gnome.org/Apps/Boxes">
<os-id>http://fedoraproject.org/fedora/28</os-id>
....
</boxes:gnome-boxes>
</metadata>
I want to add something similar to virt-manager but it seems a shame to
invent our own private schema for something that most non-trivial virt
apps will want to know about. I was thinking a schema we could document
with libosinfo, something like
<metadata>
<libosinfo
xmlns:libosinfo="http://libosinfo.org/xmlns/libvirt/domain/1.0">
<os-id>http://fedoraproject.org/fedora/28</os-id>
</libosinfo>
</metadata>
FWIW there's an oooold bug about possible tracking something like this
in the domain XML as a first class citizen:
https://bugzilla.redhat.com/show_bug.cgi?id=509164
But I think nowadays that's a bad fit and is likely off the table
Thoughts?

[libvirt] [PATCH v3 0/6] BaselineHypervisorCPU using QEMU QMP exchanges
by Chris Venteicher
Some architectures (S390) depend on QEMU to compute baseline CPU model and
expand a models feature set.
Interacting with QEMU requires starting the QEMU process and completing one or
more query-cpu-model-baseline QMP exchanges with QEMU in addition to a
query-cpu-model-expansion QMP exchange to expand all features in the model.
See "s390x CPU models: exposing features" patch set on Qemu-devel for discussion
of QEMU aspects.
This is part of resolution of: https://bugzilla.redhat.com/show_bug.cgi?id=1511999
Version 3 attempts to address all issues from V1 and V2 including making the
QEMU process activation for QMP Queries generic (not specific to capabilities)
and moving that code from qemu_capabilities to qemu_process.
I attempted to make the new qemu_process functions consistent with the functions
but mostly ended up reusing the guts of the previous functions from qemu_capabilities.
Of interest may be the choice to reuse a domain structure to hold the Qmp Query
process state and connection information. Also, pay attention to the use of a large
random number to uniquely identify decoupled processes in terms of sockets and
file system footprint. If you believe it's worth the effort I think there are some
pre-existing library functions to establish files with unique identifiers in a
thread safe way.
The last patch may also be interesting and is based on past discussion of QEMU cpu
expansion only returning migratable features except for one x86 case where
non-migratable features are explicitly requested. The patch records that features
are migratable based on QEMU only returning migratable features. The main result
is the CPU xml for S390 CPU's contains the same migratability info the X86 currently
does. The testcases were updated to reflect the change. Is this ok?
Unlike the previous versions every patch should compile independently if applied
in sequence.
Thanks,
Chris

[libvirt] [PATCH v3 0/5] libxl: PVHv2 support
by Marek Marczykowski-Górecki
This is a respin of my old PVHv1 patch[1], converted to PVHv2.
Should the code use "PVH" name (as libxl does internally), or "PVHv2" as in
many places in Xen documentation? I've chosen the former, but want to confirm
it.
Also, not sure about VIR_DOMAIN_OSTYPE_XENPVH (as discussed on PVHv1 patch) -
while it will be messy in many cases, there is
libxl_domain_build_info.u.{hvm,pv,pvh} which would be good to not mess up.
Also, PVHv2 needs different kernel features than PV (CONFIG_XEN_PVH vs
CONFIG_XEN_PV), so keeping the same VIR_DOMAIN_OSTYPE_XEN could be
confusing.
On the other hand, libxl_domain_build_info.u.pv is used in very few places (one
section of libxlMakeDomBuildInfo), so guarding u.hvm access with
VIR_DOMAIN_OSTYPE_HVM may be enough.
For now I've reused VIR_DOMAIN_OSTYPE_XEN - in the driver itself, most of
the code is the same as for PV.
Since PVHv2 relies on features in newer Xen versions, I needed to convert also
some older code. For example b_info->u.hvm.nested_hvm was deprecated in favor
of b_info->nested_hvm. While the code do handle both old and new versions
(obviously refusing PVHv2 if Xen is too old), this isn't the case for tests.
How it should be handled, if at all?
First few preparatory patches can be applied independently.
[1] https://www.redhat.com/archives/libvir-list/2016-August/msg00376.html
Changes in v2:
- drop "docs: don't refer to deprecated 'linux' ostype in example" patch -
migrating further away from "linux" os type is offtopic to this series and
apparently is a controversial thing
- drop "docs: update domain schema for machine attribute" patch -
already applied
- apply review comments from Jim
- rebase on master
Changes in v3:
- rebase on master, drop already applied patches
- use #ifdef LIBXL_DOMAIN_TYPE_PVH to detect PVH support, fix compilation
failure on older Xen
- exclude PVH from VIR_DOMAIN_OSTYPE_XEN <-> VIR_DOMAIN_OSTYPE_LINUX conversion
- fix reported capabilities for PVH
Marek Marczykowski-Górecki (5):
libxl: reorder libxlMakeDomBuildInfo for upcoming PVH support
libxl: add support for PVH
