qemu no-shutdown feature in libvirt
by Luna Xu
Hi developers,
Thanks for developing and maintaining such a great tool. I'm new and
I'm trying to use the no-shutdown feature of qemu with libvirt. I've
confirmed with the user list that currently there's no such feature in
libvirt that supports what I want to do, so I'm posting here and see
if anyone is aware of any existing project that can achieve this or
anything under development to avoid re-implementing the wheel. Here is
what I'm doing on qemu:
When I start a VM with the qemu command I can specify the -no-shutdown
flag so that my qemu process doesn't quit even if I shutdown the VM
from the inside (issue shutdown or halt command inside VM). The VM is
shutdown but the qemu process is not killed so that the jobs I
submitted before for example backup (drive-backup) can continue to run
even after VM gets shutdown by the user, and I'm able to check the
status of the job through qmp commands (by communicating with the qemu
process).
Is anyone aware of any project that is currently implementing this
functionality? Thanks for reading.
Thanks,
Luna

[PATCH] qemu_conf: Fix double free problem for cfg->firmwares
by Tuguoyi
cfg->firmwares still points to the original memory address after being
freed by virFirmwareFreeList(). As cfg get freed, it will be freed again
even if cfg->nfirmwares=0 which eventually lead to crash.
The patch fix it by setting cfg->firmwares to NULL explicitly after
virFirmwareFreeList() returns

[libvirt][PATCH v1 0/1] support system default memory policy with numatune
by Luyao Zhong
Hi libvirt experts,
---------- what does this patch support ----------
This patch seeks the support of system default memory policy
when numatune is configured. Before this patch, numatune only
has three memory modes: static, interleave and prefered.
These memory policies are ultimately set by mbind() system call.
Memory policy could be 'hard coded' into the kernel, but none of
above policies fit our requirment under this case. mbind() support
default memory policy, but it requires a NULL nodemask. So obviously
setting allowed memory nodes is cgroups' mission. That means if
'default' mode is specified in numatune, numatune config will be
completely cgroups setting, which restricting the memory
nodes allowed for each vcpu thread in different cells.
<numatune>
<memory mode="default" nodeset="1-4,^3" migratable="yes" />
<memnode cellid="0" mode="default" nodeset="1"/>
<memnode cellid="2" mode="default" nodeset="2"/>
</numatune>
Above is current design, we introduce a new "migratable" attribute and
a new option "default" for "mode" attribute in numatune.
---------- summary of discussion ----------
But at the beginning in RFC[1], Martin Kletzander and I got a consensus,
just introducing a new "migratable" attribute to indicates that we rely
on operating system to operate memory policy.
<numatune>
<memory mode="strict" nodeset="1-4,^3" migratable="yes" />
<memnode cellid="0" mode="strict" nodeset="1"/>
<memnode cellid="2" mode="preferred" nodeset="2"/>
</numatune>
the mode will be ignored, and libvirt will not set those memory policy
related configs in qemu command line.
Then initial patch got Peter Krempa's comments[2], if I understood it
correctly, that means config should not be ignored directly (I just stated
in document it will be ignored), it should be rejected in code and output
log to lead user correct the config.
But when I updated the patch, I found I had to add a new option 'default'
for mode attribute since its default value is "strict", if not setting
mode it will still be formatted to "strict" at the end. So I sent a RFC[3]
again, but unfortunately it sunk into the mail sea.
(sorry for the RFC/PATCH title changing)
[1] https://www.redhat.com/archives/libvir-list/2020-August/msg00960.html
[2] https://www.redhat.com/archives/libvir-list/2020-October/msg00396.html
[3] https://www.redhat.com/archives/libvir-list/2020-October/msg01033.html
mbind(): https://man7.org/linux/man-pages/man2/mbind.2.html
Though we have "migratable" in current implementation, actually we can
support this feauture without it since we have "default" mode, so is
"migratable" still neccessary?
Thanks for your patience to read this. Appreciate if you could give comments.

Luyao

regression in meson build, AC_PATH_PROG lost
by Olaf Hering
autoconf allows to specify the path to a runtime binary that is not required during build via an environment variable:
AC_PATH_PROG([PARTED], [parted], [], [$LIBVIRT_SBIN_PATH])
meson lacks such essential feature. As a result the package build environment needs to have more packages than necessary installed. This excessive list also pushes libvirt closer to the end of the build dependency chain.
Was this considered while the buildsystem was switched to meson?
Since meson does not support environment variables it seems the only way to address this is to introduce an option in meson_options.txt for each runtime executable.
Will such change be accepted?

[PATCH 00/21] move checks from parse functions to post parse
by Daniel Henrique Barboza
Hi,
This started as a simple NVDIMM change, then I realized there
is a Gitlab work item for it [1], so I took the extra
mile and did a bit more. I'll copy/paste here the motivation
for this kind of change, provided by Cole in [1]:
-----
The code that handles domain/VM XML parsing (virDomainDefParseXML in
src/domain/domain_conf.c) has various validation checks sprinkled
within it. Many of these checks should be moved out of the parse step
and into virDomainDefPostParse, so they can be shared by various
places in the code that build a domain definition without XML, such
as converting from native vmware/virtualbox/xen formats.
-----
There are still checks to be moved after this work. If this is
accepted I'll update [1] with more details/tips about how to proceed
with the remaining checks.
Some g_auto* cleanups were done along the way.

[PATCH v2] lxc: Cleanup after failed startup
by Michal Privoznik
If starting an container fails, the virLXCProcessStop() is
called. But since vm->def->id is not set until libvirt_lxc is
spawned (the domain's ID is PID of that process),
virLXCProcessStop() returns early as virDomainObjIsActive()
returns false. But doing so leaves behind resources reserved for
the containers during the startup process. Most notably, hostdevs
are not re-attached to the host, the domain's transient XML is
not removed, etc.
To resolve this, virLXCProcessCleanup() is called in this case.
However, it is modified to accept @flags which allows caller to
run only specific cleanups (depending how far in container
creation the failure occurred). There is plenty of cleanups which
don't need this guard because either they detect a NULL pointer
or try to release an unique resource.

[PATCH 00/24] qemu: Prepare for QAPIfied 'object-add'
by Peter Krempa
Prepare libvirt for the changes proposed for qemu:
https://www.redhat.com/archives/libvir-list/2020-November/msg01580.html
Patches 1-12/24 are pure refactors and can be merged right away.
Patches 13-15/24 can be merged, but the justification will be weak
without the rest.
Patches 16-22/24 are RFC until the qemu bits are merged.
Patch 23/24 adds capabilities and needs to be udpated later
Patch 24/24 is not to be merged!
Note that patch 23/24 is intentionally missing from the mailing list
posting as it's just a dump of QEMU capabilities from newest qemu. No
need to litter the list with it.
