vhost-user-blk bypasses the QEMU block layer, so NBD storage migration
at the QEMU level will not work for the vhost-user-blk disk.

[libvirt] Supporting vhost-net and macvtap in libvirt for QEMU
by Anthony Liguori
Disclaimer: I am neither an SR-IOV nor a vhost-net expert, but I've CC'd
people that are who can throw tomatoes at me for getting bits wrong :-)
I wanted to start a discussion about supporting vhost-net in libvirt.
vhost-net has not yet been merged into qemu but I expect it will be soon
so it's a good time to start this discussion.
There are two modes worth supporting for vhost-net in libvirt. The
first mode is where vhost-net backs to a tun/tap device. This is
behaves in very much the same way that -net tap behaves in qemu today.
Basically, the difference is that the virtio backend is in the kernel
instead of in qemu so there should be some performance improvement.
Current, libvirt invokes qemu with -net tap,fd=X where X is an already
open fd to a tun/tap device. I suspect that after we merge vhost-net,
libvirt could support vhost-net in this mode by just doing -net
vhost,fd=X. I think the only real question for libvirt is whether to
provide a user visible switch to use vhost or to just always use vhost
when it's available and it makes sense. Personally, I think the later
makes sense.
The more interesting invocation of vhost-net though is one where the
vhost-net device backs directly to a physical network card. In this
mode, vhost should get considerably better performance than the current
implementation. I don't know the syntax yet, but I think it's
reasonable to assume that it will look something like -net
tap,dev=eth0. The effect will be that eth0 is dedicated to the guest.
On most modern systems, there is a small number of network devices so
this model is not all that useful except when dealing with SR-IOV
adapters. In that case, each physical device can be exposed as many
virtual devices (VFs). There are a few restrictions here though. The
biggest is that currently, you can only change the number of VFs by
reloading a kernel module so it's really a parameter that must be set at
startup time.
I think there are a few ways libvirt could support vhost-net in this
second mode. The simplest would be to introduce a new tag similar to
<source network='br0'>. In fact, if you probed the device type for the
network parameter, you could probably do something like <source
network='eth0'> and have it Just Work.
Another model would be to have libvirt see an SR-IOV adapter as a
network pool whereas it handled all of the VF management. Considering
how inflexible SR-IOV is today, I'm not sure whether this is the best model.
Has anyone put any more thought into this problem or how this should be
modeled in libvirt? Michael, could you share your current thinking for
-net syntax?

[libvirt] [python] WIP-FYI: mypy annotations for libvirt-python
by Philipp Hahn
Hello,
Maybe you already have heads about mypy <http://mypy-lang.org/>, which
"is an experimental optional static type checker for Python that aims to
combine the benefits of dynamic (or "duck") typing and static typing".
I started to write a manual annotation file for the Python binding of
libvirt. I've attached my current version, so others can benefit from
it, too. It is far from complete, but it already helped my to find some
errors in my code.
(My latest version is also available at
<https://github.com/univention/typeshed/blob/libvirt/third_party/2and3/lib...>)
Long-term it probably would be better to teach the Python binding
"generator.py" to add the type information (PEP 484
<https://www.python.org/dev/peps/pep-0484/>) directly into the generated
"libvirt.py" file, but that's for another day.
If someone else is interested in helping with that, please feel free to
get in contact.
Philipp

[libvirt] [PATCH 0/3] Fix ppc64 CPU configuration for QEMU 2.11+
by Jiri Denemark
The original fix was both incomplete and too general. It only fixed
domain startup, but libvirt would still report empty list of supported
CPU models with recent QEMU for ppc64. On the other hand, while ppc64
QEMU ignores case when looking up CPU model names, x86_64 QEMU does
case sensitive lookup.
Jiri Denemark (3):
Revert "domcaps: Treat host models as case-insensitive strings"
util: Introduce virStringListSearch
qemu: Adapt to changed ppc64 CPU model names

[libvirt] [PATCHv3 0/5] Implement debugcon chardev
by Ján Tomko
v2: https://www.redhat.com/archives/libvir-list/2019-February/msg00293.html
v3:
* dropped the pointless isa-prefix
* use DO_TEST_CAPS_LATEST
* trimmed the XML
* compiles with gcc
* only make irq optional
* autofill iobase
Ján Tomko (3):
qemu: introduce qemuDomainChrSerialTargetModel
qemu: make irq optional when formatting the ISA address
qemu: autoadd iobase to debugcon chardev
Nikolay Shirokovskiy (2):
conf: add debugcon chardev guest interface
qemu: implement debugcon chardev

[libvirt] New Feature: Intel MKTME Support
by Carvalho, Larkins L
Hello Team,
Greetings.
We want to add Intel MKTME support to the Libvirt.
Intel MKTME is a capability to encrypt entirety of physical memory of a system similar to AMD SEV.
Please let us know what are the expectations from us to initiate the design and development of the feature.
Regards,
