[libvirt] [PATCH 00/12] qemu: support chardev for all machvirt config
by Cole Robinson
Drew pointed out that we can use -chardev with machvirt platform
serial devices like:
-chardev pty,id=foo
-serial chardev:foo
And indeed it looks like qemu has supported this for as long as -chardev
has been around. Wiring this up will enable all the modern -chardev
features for every machvirt config (and some other arch/machine types).
However just enabling that change is going to cause a lot of unneeded
test suite churn, due to the fact that some code is still checking for
qemu -chardev support, even though our minimum qemu version always has
chardev nowadays. So take the opportunity to exorcise QEMU_CAPS_CHARDEV
* Patch 1 reverts Christopher's recent patch, to unbreak existing configs
* Patch 2-3 make pci-serial work for machvirt and demonstrate it with a
test suite change.
* Patch 4-10 slowly strip out QEMU_CAPS_DEVICE
* Patch 11 adds -chardev support for platform serial devices
* Patch 12 is a cleanup

[libvirt] [PATCH v2] qemu: Check for existence of provided *_tls_x509_cert_dir
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1458630
Introduce virQEMUDriverConfigSetCertDir which will handle reading the
qemu.conf config file specific setting for default, vnc, spice, chardev,
and migrate. If a setting is provided, then validate the existence of the
directory and overwrite the default set by virQEMUDriverConfigNew.
Update the qemu.conf description for default to describe the consequences
if the default directory path does not exist and as well as the descriptions
for each of the *_tls_x509_cert_dir entries.
Signed-off-by: John Ferlan <jferlan(a)redhat.com>
---
v1: https://www.redhat.com/archives/libvir-list/2017-June/msg01278.html
- Dropped the former 1/2 patch
- Alter the logic of virQEMUDriverConfigSetCertDir to fail instead of
VIR_INFO if an uncommented entry for one of the *_tls_x509_cert_dir
has a path that does not exist. This will cause a libvirtd startup
failure as opposed to the previous logic which would have failed only
when a domain using TLS was started.
- Alter the description for each of the values to more accurately describe
what happens.

[libvirt] [PATCH v3 00/16] qemu: migration: show disks stats for nbd migration
by Nikolay Shirokovskiy
diff from v2:
============
1. Fix style issues.
2. Rework patch for fetching job info
(save logic to use temporary variable when drop vm lock)
3. Update disk stats when block jobs are canceled.
4. Adress a few more corner cases.
This patch series add disks stats to domain job info(stats) as
well as to migration completed event in case nbd scheme is used.
There is little nuisance with qcow2 disks (which is the main scenario
I guess) tied to the way qemu reports stats for this type of disks.
For example if we have 64G disk filled only to 1G then stats
start from 63G and will grow up to 64G on completion. The same way disk stats
will be reported by this patch.
I guess the better way to express the situation is to say we have 64G 'total',
and have 'processed' field grow from 0G to 1G, like in case of memory
stats. [1] is the example of completed memory stats of empty guest
domain, which show difference between processed and total.
There can be a workaround like getting initial blockjob offset position
as a zero but is is rather ugly and racy and like uses undocumented
behaviour.
[1] memory migration stats example
Memory processed: 3.307 MiB
Memory remaining: 0.000 B
Memory total: 1.032 GiB
The above is applied to qemu 2.6 at least.
Patches that were explicitly ACKed in previous review
(up to style issues) marked with A.

[libvirt] [PATCH] Use unsigned timeout in cmdMigrateSetMaxDowntime
by Scott Garfinkle
While looking to implement a migrate-getmaxdowntime command (coming),
I noticed that the setmaxdowntime is incorrectly looking at its
parameter as a signed longlong. Not sure how that got past gcc, but
here's a simple patch to make the command line parsing and the parameter to
the worker functions all have the correct (unsigned) type.

[libvirt] [RFC PATCH v2 0/4] numa: describe sibling nodes distances
by Wim Ten Have
From: Wim ten Have <wim.ten.have(a)oracle.com>
This patch extents guest domain administration adding support to advertise
node sibling distances when configuring HVM numa guests.
NUMA (non-uniform memory access), a method of configuring a cluster of nodes
within a single multiprocessing system such that it shares processor
local memory amongst others improving performance and the ability of the
system to be expanded.
A NUMA system could be illustrated as shown below. Within this 4-node
system, every socket is equipped with its own distinct memory. The whole
typically resembles a SMP (symmetric multiprocessing) system being a
"tightly-coupled," "share everything" system in which multiple processors
are working under a single operating system and can access each others'
memory over multiple "Bus Interconnect" paths.
+-----+-----+-----+ +-----+-----+-----+
| M | CPU | CPU | | CPU | CPU | M |
| E | | | | | | E |
| M +- Socket0 -+ +- Socket3 -+ M |
| O | | | | | | O |
| R | CPU | CPU <---------> CPU | CPU | R |
| Y | | | | | | Y |
+-----+--^--+-----+ +-----+--^--+-----+
| |
| Bus Interconnect |
| |
+-----+--v--+-----+ +-----+--v--+-----+
| M | | | | | | M |
| E | CPU | CPU <---------> CPU | CPU | E |
| M | | | | | | M |
| O +- Socket1 -+ +- Socket2 -+ O |
| R | | | | | | R |
| Y | CPU | CPU | | CPU | CPU | Y |
+-----+-----+-----+ +-----+-----+-----+
In contrast there is the limitation of a flat SMP system, not illustrated.
Here, as sockets are added, the bus (data and address path), under high
activity, gets overloaded and easily becomes a performance bottleneck.
NUMA adds an intermediate level of memory shared amongst a few cores per
socket as illustrated above, so that data accesses do not have to travel
over a single bus.
Unfortunately the way NUMA does this adds its own limitations. This,
as visualized in the illustration above, happens when data is stored in
memory associated with Socket2 and is accessed by a CPU (core) in Socket0.
The processors use the "Bus Interconnect" to create gateways between the
sockets (nodes) enabling inter-socket access to memory. These "Bus
Interconnect" hops add data access delays when a CPU (core) accesses
memory associated with a remote socket (node).
For terminology we refer to sockets as "nodes" where access to each
others' distinct resources such as memory make them "siblings" with a
designated "distance" between them. A specific design is described under
the ACPI (Advanced Configuration and Power Interface Specification)
within the chapter explaining the system's SLIT (System Locality Distance
Information Table).
These patches extend core libvirt's XML description of a virtual machine's
hardware to include NUMA distance information for sibling nodes, which
is then passed to Xen guests via libxl. Recently qemu landed support for
constructing the SLIT since commit 0f203430dd ("numa: Allow setting NUMA
distance for different NUMA nodes"), hence these core libvirt extensions
can also help other drivers in supporting this feature.
The XML changes made allow to describe the <cell> (or node/sockets) <distances>
amongst <sibling> node identifiers and propagate these towards the numa
domain functionality finally adding support to libxl.
[below is an example illustrating a 4 node/socket <cell> setup]
<cpu>
<numa>
<cell id='0' cpus='0,4-7' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='10'/>
<sibling id='1' value='21'/>
<sibling id='2' value='31'/>
<sibling id='3' value='41'/>
</distances>
</cell>
<cell id='1' cpus='1,8-10,12-15' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='21'/>
<sibling id='1' value='10'/>
<sibling id='2' value='21'/>
<sibling id='3' value='31'/>
</distances>
</cell>
<cell id='2' cpus='2,11' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='31'/>
<sibling id='1' value='21'/>
<sibling id='2' value='10'/>
<sibling id='3' value='21'/>
</distances>
</cell>
<cell id='3' cpus='3' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='41'/>
<sibling id='1' value='31'/>
<sibling id='2' value='21'/>
<sibling id='3' value='10'/>
</distances>
</cell>
</numa>
</cpu>
By default on libxl, if no <distances> are given to describe the SLIT data
between different <cell>s, this patch will default to a scheme using 10
for local and 21 for any remote node/socket, which is the assumption of
guest OS when no SLIT is specified. While SLIT is optional, libxl requires
that distances are set nonetheless.
On Linux systems the SLIT detail can be listed with help of the 'numactl -H'
command. An above HVM guest as described would on such prompt with below output.

[libvirt] [v2 RESEND PATCH] qemu: reduce packet loss rate for vm with macvtap passthrough mode in migration
by ZhiPeng Lu
Before libvirt that calls virNetDevMacVLanCreateWithVPortProfile sets mac address
or vlan of a Virtual Function(VF) linked to a macvtap passthrough device of migration
destination host in migration start step. If we ping the migrating vm,
we get the network does not pass. Because VFs of migration source and destination
have the same MAC address. The patch later calling qemuMigrationVPAssociatePortProfiles
sets mac address of VF in migration finish step instead of start step.
The patch aims to reduce packet loss rate.

[libvirt] [PATCH 0/3] exposing busy polling support for vhost-net
by sferdjao＠redhat.com
From: Sahid Orentino Ferdjaoui <sahid.ferdjaoui(a)redhat.com>
In version 2.7.0, QEMU introduced support of busy polling for
vhost-net [0]. To avoid paraphrasing original authors of that feature
and the purpose it I prefer to share a pointer [1].
This patch serie exposes throught the NIC driver-specific element a
new option 'poll_us'. That option is only available with the backend
driver 'vhost'.
The option 'poll_us' takes a positive number. 0 means that the option
is not going to be exposed.
