[libvirt] [jenkins-ci PATCH] lcitool: don't use SafeConfigParser under Python3
by Daniel P. Berrangé
Since Python 3.2 the SafeConfigParser class is renamed to
just ConfigParser. The SafeConfigParser alias is targetted
for deletion.
./lcitool:224: DeprecationWarning: The SafeConfigParser class
has been renamed to ConfigParser in Python 3.2. This alias
will be removed in future versions. Use ConfigParser directly
instead.
This switches to use ConfigParser all the time on Py3. Technically
this is wrong on 3.0 and 3.1, but in reality no one will still be
using those, only more modern 3.x versions, or the legacy 2.7.

[libvirt] [PATCH] RFC: use a slirp helper process
by marcandre.lureau@redhat.com
From: Marc-André Lureau <marcandre.lureau(a)redhat.com>
I am throwing this away for discussions, and early feedback.
With the upcoming release of libslirp[1], we have an opportunity to
run SLIRP networking in a separate process. This will allow for
stricter security policies for both qemu & slirp, as slirp is
notoriously not very safe (discussed on ML, various CVEs, and even the
code says so explicitly in the comments), yet people rely on it regularly.
For network type "user", libvirt could spawn an helper process (an
experimental version is [2]). It would setup a socket pair between
qemu and the helper and use -net socket. qemu could then be built
without libslirp! (imho, qemu should deprecate built-in -net user
support, and doesn't need to grow its own sub-process handling)
This libvirt patch is a bit rough, I am not sure where things should
go. In particular, how to manage the subprocesses properly (security
aspects, and lifecycle etc), and how to deal with migration (prevent
migrating from non-helper to helper version etc).
It seems guestfwd has been non-functional for a while. This is also
something that the current experimental helper doesn't support
atm. Doing all the various "channel" types that libvirt/qemu support
would be tedious, and probably unnecessary. But the underlying
libslirp library support redirections the same way qemu does today, so
it could be added if necessary.
At this point, the slirp-helper doesn't handle migration. But is it
really worth it? From a guest POV, it would look like packet lost or
disconnection. Adding migration handling is possible, to avoid a
disconnection event. How should it be done? via a libvirt provided
socket for storage? via its own file transferred by libvirt? via qemu
somehow (qemu wouldn't really know about the external process but
would copy around the migration bits?).
Does the helper need to have a "standard" & capabilities, similar to
what is proposed for vhost-user [3]? This would allow for easier
competing implementation to emerge (I have plans in mind, not using
libslirp).
Thanks for the feedback!

[libvirt] [PATCH v2 1/1] tests/virhostdevtest: remove virHostdevHostSupportsPassthroughKVM
by Daniel Henrique Barboza
virhostdevtest is using pci mock to emulate all PCI attach/detach
operations. This means that that this test does not rely on KVM
support of the host anymore and the tests in this file shouldn't
be affected by it.

[libvirt] [PATCH v2 0/8] CPU Model Baseline and Comparison for s390x
by walling@linux.ibm.com
From: Collin Walling <walling(a)linux.ibm.com>
Changelog:
v1
- introduce baseline
- split patches into small chunks
- free'd lingering qemuMonitorCPUModelInfo pointer
- when converting from virCPUDef -> virJSON, consider
feature policy FORCED for enabled
This is the second iteration of the CPU Model Comparison and
Baseline patches for s390x. The previous version only showed
comparison as a preview, and it can be found here:
https://www.redhat.com/archives/libvir-list/2019-April/msg01046.html
The first patch pull some code out of the CPU Model Expansion
JSON function so that it can be later used for the Comparison
and Baseline JSON functions.
The rest of the patches follow this sequence:
- introduce JSON monitor functions
- introduce capability and update test files
- hook up monitor functions to virsh command
Thanks
@Daniel, I added your Tested-by where I felt made most sense.
Collin Walling (8):
qemu_monitor: helper functions for CPU models
qemu_monitor: implement query-cpu-model-baseline
qemu_capabilities: introduce QEMU_CAPS_QUERY_CPU_MODEL_BASELINE
qemu_driver: hook up query-cpu-model-baseline
qemu_monitor: implement query-cpu-model-comparison
qemu_capabilities: introduce QEMU_CAPS_QUERY_CPU_MODEL_COMPARISON
cpu_conf: xml to cpu definition parse helper
qemu_driver: hook up query-cpu-model-comparison

[libvirt] [PATCH 1/1] util/virhostdev: consolidate duplicated KVM support code
by Daniel Henrique Barboza
tests/virhostdevtest.c implements a function called
'virHostdevHostSupportsPassthroughKVM', that is equal to
'qemuHostdevHostSupportsPassthroughLegacy' that is declared
inside qemu/qemu_hostdev.c.
This patch removes the duplicated code from both files and
and puts it inside util/virhostdev.c, under the name
virHostdev...KVM, which represents what the code does better
than using 'Legacy'.
