[libvirt] Question about virtio-pci in Aarch64
by Kevin Zhao
Hi Cole && All,
Nice meeting you in the libvirt mail-list. Greetings from Linaro !!!
I am Kevin Zhao from Linaro and working for OpenStack on Aarch64.
Nowadays I find that the default "virtio" bus is "virtio-mmio" , not
"virtio-pci". Since virtio-mmio do not has the host plugged function ,
something is wrong with the function in OpenStack Nova.
Then I search and find some mail information as belows by Cole :-)
1)
https://www.redhat.com/archives/libvir-list/2015-December/msg00217.html
2)
https://www.redhat.com/archives/libvir-list/2016-March/msg00167.html
I see some efforts have been doing by you. Really thanks for your
efforts for Aarch64. And I have some small questions.
1. Is Libvirt planning to replace the default virtio-mmio to
virtio-pci for Aarch64?
2. If not , how can I change the xml file(generated by Virsh) for
virtio-pci so that Qemu can recognize it ?
Really big thanks for your help. Looking forwards to your response!
Best Regards,
Kevin Zhao

[libvirt] [PATCH 0/7]
by Nikolay Shirokovskiy
filesystem pools inception
Filesystem pools is a facility to manage filesystems resources similar
to how storage pools manages volume resources. Furthermore new API follows
storage API closely where it makes sense. Uploading/downloading operations
are not defined yet as it is not obvious how to make it properly. I guess
we can use some kind of tar to make a stream from a filesystem. Please share
you thoughts on this particular issue.
The patchset provides 'dir' backend which simply expose directories in some
directory in host filesystem. The virsh commands are provided too. So it is
ready to play with, just replace 'pool' in xml descriptions and virsh commands
to 'fspool' and 'volume' to 'item'.
Olga Krishtal (7):
fspool: introduce filesystem pools API
fspool: usual driver based implementation of filesystem pools API
fspools: configuration and internal representation
fspools: acl support for filesystem pools
remote: filesystem pools driver implementation
fspool: default implementation of filesystem pools
virsh: filesystem pools commands

[libvirt] [PATCH v1 00/19] Implementation of QEMU vhost-scsi
by Eric Farman
This patch series provides a libvirt implementation of the vhost-scsi
interface in QEMU. As near as I can see, this was discussed upstream in
July 2014[1], and ended in a desire to replace a vhost-scsi controller
in favor of a hostdev element instead[2].
There is no capability check in this series for vhost-scsi in the underlying
QEMU. Using a recent QEMU built with --disable-vhost-scsi fails with "not a
valid device model name."
Host Filesystem Example:
# ls /sys/kernel/config/target/vhost/
discovery_auth naa.5001405df3e54061 version
# ls /sys/kernel/config/target/vhost/naa.5001405df3e54061/tpgt_1/lun/
lun_0
QEMU Example (snippet):
-device vhost-scsi-ccw,wwpn=naa.5001405df3e54061,devno=fe.0.1000
Libvirt Example (snippet):
<hostdev mode='subsystem' type='scsi'>
<source protocol='vhost' wwpn='naa.5001405df3e54061'/>
<address type='ccw' cssid='0xfe' ssid='0x0' devno='0x1000'/>
</hostdev>

[libvirt] [PATCH RFC 0/8] qemu: allow disabling certain virtio revisions
by Ján Tomko
For https://bugzilla.redhat.com/show_bug.cgi?id=1227354
some users might want to adjust the QEMU defaults and disable
either virtio 0.9 or virtio 1.0 (spelled out as disable-legacy
and disable-modern on qemu command line).
This series uses a separate <virtio revision="x"> element
right under the relevant device element for consistency,
even though it might fit better in different subelemets for
some of them.
Ján Tomko (8):
Fix indentation
Add virtio revision attribute to memballoon
Add virtio revision attribute to disks
Add virtio revision attribute to controllers
Add virtio revision attribute to filesystems
Add virtio revision attribute to intefaces
Add virtio revision to rng devices

[libvirt] [PATCH v4 0/4] perf: add more perf events support
by Qiaowei Ren
With current perf framework, this patchset refactor virPerfEventEnable()
for general purpose and add more perf events support based on this change,
including cache misses, cache references, cpu cycles, instrctions, etc..
Changes since v3:
* separate the patch into 4 patches.
* update virsh.pod for new perf events.
* introduce a static attr table that would be able to convert the
VIR_PERF_EVENT_* into their respective "attr.type" and "attr.config".
