[ruby PATCH] Fix cpumap allocation for virDomainGetVcpus and use return value
by Charlie Smurthwaite
This patch fixes a bug in which only enough memory for one cpumap is
allocated
for virDomainGetVcpus instead of one per virtual CPU. This Fixes an
overflow.
Additionally, it uses the return value of virDomainGetVcpus to determine how
many cpuinfo structs were actually populated rather than assuming they
all are.
Finally, it uses the logical CPU number from the cpuinfo struct in the
retrurn
data instead of assuming CPU numbers are sequential. This should handle
cases
where arbitrary CPUs are offline.

[libvirt PATCH] docs: Expand documentation for the tickpolicy timer attribute
by Andrea Bolognani
The current documentation is fairly terse and not easy to decode
for someone who's not intimately familiar with the inner workings
of timer devices. Expand on it by providing a somewhat verbose
description of what behavior each policy will result in, as seen
from both the guest OS and host point of view.
This is lifted directly from QEMU commit
commit 2a7d957596786404c4ed16b089273de95a9580ad
Author: Andrea Bolognani <abologna(a)redhat.com>

found in QEMU.

[PATCH v1 0/3] qemumonitorjson tests for cpu compare and baseline
by Collin Walling
These patches implement tests for the libvirt qemu_monitor_json API for
the hypervisor-cpu-compare and -baseline commands. The input and output
data is mocked with arbitrary values.
A prerequisite patch is included to load the capabilities schema for
a specific architecture. Originally, only the x86 capabilities were
loaded for the qemu_monitor_json tests. By accepting a string denoting
which architecture's QEMU capabilities we'd like to load, we can now
test the comparison and baseline code that is currently only supported
on s390.

[libvirt PATCH] m4: libxl: properly fail when libxl is required
by Ján Tomko
We specify "true" as the fail-action for LIBVIRT_CHECK_PKG.
This was used when we had a fallback to non-pkg-config detection,
then removed in commit 5bdcef13d13560512c7d6d8c9e8822e456889e0c
later re-introduced in commit dc3d2c9f8c7678a950abedd227b1587ca62335c4
and then left in when removing the old detection again in
commit 18981877d2e20390a79d068861a24e716f8ee422
Remove it to properly error out when libxl was requested but not

[libvirt PATCH 00/10] support BR_ISOLATED flag for guest interfaces attached to a Linux host bridge
by Laine Stump
https://bugzilla.redhat.com/1727263
Since Linux kernel 4.18, the Linux host bridge has had a flag
BR_ISOLATED that can be applied to individual ports. When this flag is
set for a port, traffic is blocked between that port and any other
port that also has the BR_ISOLATED flag set. libvirt domain interface
config now supports setting this flag via the <portOptions
isolated='yes'/> setting. It can also be set for all connections to
a particular libvirt network by setting the same option in the network
config - since the port for the host itself does not have BR_ISOLATED
set, the guests can communicate with the host and the outside world,
but guests on that network can't communicate with each other. This
feature works for QEMU and LXC guests with interfaces attached to a
Linux host bridge.
(I had contemplated (and experimented with) putting this new flag in
the <virtualport> element to avoid creating a new element, but that
ended up creating lots of extra code since none of the existing
virtualport types would support this new flag, Linux host bridges
already work with *no* <virtualport> (much less a virtualport type),
and there are some attributes in the <virtualport> parameters
subelement that are always autogenerated if there is no virtualport
type specified, so I would needed to add a new virtualport type for
Linux host bridge, which seems redundant as that information is
already implicit in the interface's connection type. etc. etc. It all
just turned into a big mess, and starting over fresh with something
generic (and hopefully expandable in a sensible way) seemed
cleaner). (I am of course open to suggestions though!)
Laine Stump (10):
schema: trivial indentation fix
schema: add missing vlan element to networkport RNG
qemu: save/restore original error when recovering from failed bridge
attach
util: query/set BR_ISOLATED flag on netdevs attached to bridge
conf: parse/format <portOptions isolated='yes|no'/>
network: propagate <portOptions isolated='yes'/> between network and
domain

sharing some timer devices between host and LXC guest using `timer`

as virtual cpuinfo content based on VCPU settings and some better
resource limits. Each patch has the description of the problem and what
it is trying to fix.
