[PATCH] virt-host-validate: Fix IOMMU output on aarch64
by Fabiano Fidêncio
virt-host-validate should print "Checking for device assignment IOMMU
support" for all architectures, not only for Intel / AMD.
This is the output without the patch:
```
[fidencio@dentola libvirt]$ virt-host-validate

QEMU: comprobando if device /dev/kvm is accessible : PASA

ADVERTENCIA (Unknown if this platform has IOMMU support)
QEMU: comprobando for secure guest support : ADVERTENCIA (Unknown if this platform has Secure Guest support)
```
This is the output with the patch:

[libvirt PATCH 0/2] Update sync_qemu_i386.py tool for changes in QEMU
by Tim Wiederhake
QEMU commit e11fd68996fb27c040552320f01a7d30a15a7cc1 changed a line that
was used by our tool as marker. Commit 1 prepares for the change, commit 2
actually makes the required adjustment.
Cheers,
Tim

[libvirt PATCH 0/4] Support autostart for mediated devices
by Jonathon Jongsma
This is a short patch series based on an initial patch from Boris Fiuczynski
that I massaged a little bit and added a few additional patches.
This allows you to define mediated devices in libvirt which are started
automatically at boot or parent device plugin.

[PATCH] apparmor: Add denied capabilities

The audit log contains the following denials from libvirtd
apparmor="DENIED" operation="capable" profile="libvirtd" pid=6012 comm="daemon-init" capability=17 capname="sys_rawio"
apparmor="DENIED" operation="capable" profile="libvirtd" pid=6012 comm="rpc-worker" capability=39 capname="bpf"
apparmor="DENIED" operation="capable" profile="libvirtd" pid=6012 comm="rpc-worker" capability=38 capname="perfmon"
Squelch the denials and allow the capabilities in the libvirtd
apparmor profile.
Signed-off-by: Jim Fehlig <jfehlig(a)suse.com>

I'm not really sure when these denials first started appearing, nor
have I noticed any problems they are causing. Likely I have not exercised
the affected functionality.

[PATCH] storage: Don't overwrite error in virISCSIDirectDisconnect()
by Michal Privoznik
The iscsi-direct storage pool backend works merely like this: a
connection is established to the target (usually done via
virStorageBackendISCSIDirectSetConnection()), intended action is
executed (e.g. reporting LUNs, volume wiping), and at the end the
connection is closed via virISCSIDirectDisconnect().
The problem is that virISCSIDirectDisconnect() reports its own
errors which may overwrite error that occurred during LUN
reporting, or volume wiping or whatever.
To fix this, use virErrorPreserveLast() + virErrorRestore()
combo, which either preserves previously reported error message,
or is NOP if there's no error reported.

[PATCH] meson.build: Compile with -Walloca
by Thomas Huth
We are already compiling libvirt with -Wvla - so it does not make
too much sense to still allow people to use alloca() instead. Thus
put it on the list of things we want to warn about. Fortunately,
there is currently no warning with this flag, so the current
sources should be clean.

[PATCH] meson.build: Remove the -Wvla-larger-then flag
by Thomas Huth
The flag has a typo in it, it's "...-than=..." and not "...-then=...",
so this was in fact never used. Since we're also using -Wvla (without
size), we should already get warnings about any variable length arrays
anyway, so the additional "-Wvla-larger-than" does not make much sense
and thus we can simply drop this.
