question on vhost, limiting kernel threads and NPROC
by Mike Christie
Hi,
The goal of this email is to try and figure how we want to track/limit the
number of kernel threads created by vhost devices.
Background:
-----------
For vhost-scsi, we've hit a issue where the single vhost worker thread can't
handle all IO the being sent from multiple queues. IOPs is stuck at around
500K. To fix this, we did this patchset:
https://lore.kernel.org/linux-scsi/20210525180600.6349-1-michael.christie...
which allows userspace to create N threads and map them to a dev's virtqueues.
With this we can get around 1.4M IOPs.
Problem:
--------
While those patches were being reviewed, a concern about tracking all these
new possible threads was raised here:
https://lore.kernel.org/linux-scsi/YL45CfpHyzSEcAJv@stefanha-x1.localdomain/
To save you some time, the question is what does other kernel code using the
kthread API do to track the number of kernel threads created on behalf of
a userspace thread. The answer is they don't do anything so we will have to
add that code.
I started to do that here:
https://lkml.org/lkml/2021/6/23/1233
where those patches would charge/check the vhost device owner's RLIMIT_NPROC
value. But, the question of if we really want to do this has come up which is
why I'm bugging lists like libvirt now.
Question/Solution:
------------------
I'm bugging everyone so we can figure out:
If we need to specifically track the number of kernel threads being made
for the vhost kernel use case by the RLIMIT_NPROC limit?
Or, is it ok to limit the number of devices with the RLIMIT_NOFILE limit.
Then each device has a limit on the number of threads it can create.

[PATCH v4 for v7.6.0 00/14] Introduce virtio-mem <memory/> model
by Michal Privoznik
v4 of:
https://listman.redhat.com/archives/libvir-list/2021-April/msg01138.html
diff to v3:
- Rebased code on the top of master
- Tried to work in all Peter's review suggestions
- Fixed a bug where adjusting <requested/> was viewed as hotplug of new
<memory/> by XML validator and thus if <maxMemory/> was close enough to
<currentMemory/> the validator reported an error (this was reported by
David).
You can also find these patches on my branch:

[PATCH 0/9] Fix image labels lost after migration with shared fs
by Peng Liang
When migrating using shared fs, the dst host will remember the image
labels again before launching the VM and the src host will remove the
image labels after migration. It leads to that the image labels lost
after migration.
Patch 7-9 are the real fix patches.
Peng Liang (9):
security: add virSecurityUpdateTimestampIfexists
security: add virSecurityManagerUpdateImageLabel
security: implement domainUpdateSecurityImageLabel for stack
security: implement domainUpdateSecurityImageLabel for DAC
qemu: add qemuSecurityUpdateImageLabel
security: rename virSecurityDACSetImageLabelInternal to
virSecurityDACSetImageLabelSingle
migration: don't remember image labels when migrating with shared fs
migration: don't remove image labels after migration
migration: update image labels in dst after migration

[libvirt PATCH v3 0/7] Enable autostarting mediated devices
by Jonathon Jongsma
This first version of this series was reviewed quite a while ago and all
patches were ACKed except the second one. I posted a second series with changes
noted below but it was never ACKed and I dropped the ball for a little while.
Subsequently there were questions about whether physical devices (e.g. pci,
usb, etc) should return 'true' or 'false' for the GetAutostart()/IsPersistent()
calls. I had initially marked them as persistent=true and autostart=true
because they superficially act a bit like persistently-defined devices. But
Boris convinced me that this is not a very accurate classification since if the
physical device is unplugged, there will be no record of it left behind. So
I've switched all non-mdev devices to be persistent=false and autostart=false.
This is also imperfect, but it seems relatively harmless. Comments welcome.
A reminder of what is included in this series:
- new API consistent with existing libvirt objects:
- virNodeDeviceGetAutostart()
- virNodeDeviceSetAutostart()
- virNodeDeviceIsPersistent()
- virNodeDeviceIsActive
- new virsh commands
- nodedev-info
- nodedev-autostart
Changes in version 2:
- Parse the autostart property from mdevctl output.
Changes in version 3:
- switch physical devices to autostart=false, persistent=false
- rebase to upstream
- update version numbers for new API, etc
- fix accidental copy-paste error in virsh command descriptions
Jonathon Jongsma (7):
api: add virNodeDevice(Get|Set)Autostart()
nodedev: implement virNodeDevice(Get|Set)Autostart()
nodedev: Add tests for mdevctl autostart command
virsh: add nodedev-autostart
api: add virNodeDeviceIsPersistent()/IsActive()
nodedev: Implement virNodeDeviceIsPersistent()/IsActive()
virsh: add nodedev-info

[PATCH 0/1] qemu: add virtio-blk queue-size option
by Hiroki Narukawa
Hello,
The option "queue-size" in virtio-blk was added in qemu-2.12.0, and default value increased from qemu-5.0.0.
However, increasing this value may lead to drop of random access performance.
This is configurable value, so we want to use it via libvirt.
Sorry, my previous e-mail had wrong CC address that is rejected, please
reply to this message and not previous one.
Could you review this patch?

[PATCH 2/2] qemu: support for virtio-blk-pci discard options
by yuxiating
DISCARD and WRITE_ZEROES features for machine type >= 4.0 is enabled by default since
commit 5c81161f804144b146607f890e84613a4cbad95c
virtio-blk: add "discard" and "write-zeroes" properties
Sometimes guestos has bugs DISCARD need to be disabled.
