[libvirt] [dbus PATCH] Install daemon under @sbindir@
by Andrea Bolognani
The libvirt-dbus daemon is not supposed to be invoked
explicitly by the user, but rather to be spawned on-demand
by the D-Bus daemon: as such, @sbindir@ is a more suitable
location in which to install it.

[libvirt] [PATCH] qemu: qemuDomainChangeNet: don't overwrite device info when pci addr is missing
by Katerina Koukiou
When trying to update an interface's rom settings with an device XML
that is missing the PCI addr element, all new rom settings where not applied.
https://bugzilla.redhat.com/show_bug.cgi?id=1599513
Signed-off-by: Katerina Koukiou <kkoukiou(a)redhat.com>

Not sure why we chose to overwrite the whole info before though, I hope
that this doesn't cause side problems.

[libvirt] [PATCH] util: avoid symbol clash between json libraries
by Daniel P. Berrangé
The jansson and json-glib libraries both export symbols with a json_
name prefix and json_object_iter_next() clashes between them.
Unfortunately json_glib is linked in by GTK, so any app using GTK and
libvirt will get a clash, resulting in SEGV. This also affects the NSS
module provided by libvirt
Instead of directly linking to jansson, use dlopen() with the RTLD_LOCAL
flag which allows us to hide the symbols from the application that loads
libvirt or the NSS module.
Some preprocessor black magic and wrapper functions are used to redirect
calls into the dlopen resolved symbols.

[libvirt] [PATCH v2 RESEND 00/12] PCI passthrough support on s390
by Yi Min Zhao
Abstract
========
The PCI representation in QEMU has recently been extended for S390
allowing configuration of zPCI attributes like uid (user-defined
identifier) and fid (PCI function identifier).
The details can be found here:
https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg07262.html
To support the new zPCI feature of the S390 platform, two new XML
attributes, @uid and @fid, are introduced for device addresses of type
'pci', i.e.:
<hostdev mode='subsystem' type='pci'>
<driver name='vfio'/>
<source>
<address domain='0x0001' bus='0x00' slot='0x00' function='0x0'/>
</source>
<address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'
uid='0x0003' fid='0x00000027'/>
</hostdev>
uid and fid are optional attributes. If they are defined by the user,
unique values within the guest domain must be used. If they are not
specified and the architecture requires them, they are automatically
generated with non-conflicting values.
Current implementation is the most seamless one for the user as it
unites the address specific data of a PCI device on one XML element.
It could accommodate both specifying our special parameters (uid and fid)
and re-using standard statements (domain, bus, slot and function) for
PCI devices. User can still specify bus/slot/function for the virtualized
PCI devices in the XML.
Thus uid/fid act as an extension to the PCI address and are stored in
a new structure 'virZPCIDeviceAddress' which is a member of common PCI
Address structure. Additionally, two hashtables are used for assignment
and reservation of uid/fid.
In support of extending the PCI address, a new PCI address extension flag is
introduced. This extension flag allows is not only dedicated for the S390
platform but also other architectures needing certain extensions to PCI
address space.

[libvirt] [PATCH v2] util: avoid symbol clash between json libraries
by Daniel P. Berrangé
The jansson and json-glib libraries both export symbols with a json_
name prefix and json_object_iter_next() clashes between them.
Unfortunately json_glib is linked in by GTK, so any app using GTK and
libvirt will get a clash, resulting in SEGV. This also affects the NSS
module provided by libvirt
Instead of directly linking to jansson, use dlopen() with the RTLD_LOCAL
flag which allows us to hide the symbols from the application that loads
libvirt or the NSS module.
Some preprocessor black magic and wrapper functions are used to redirect
calls into the dlopen resolved symbols.

[libvirt] [PATCH 00/11] Add checks to ensure a name isn't all whitespace
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1107420
As unusual as the case may be, having a name of all white space
has been allowed. This leads to the obvious problem of how a future
usage would be able to "utilize" that resource since it's not "simple"
to determine what combination of spaces and tabs are being used for
the name.
So add code to various drivers in order to inhibit this for those
resources that would consider using a name for some sort of lookup
type reference. For a majority of drivers, the schema validation also
allowed the name; however, a couple (secrets and nwfilters) the
virt-xml-validate would fail. Still this wouldn't necessarily stop
someone - just slow them down. So for those the test xml file must
use the *-invalid.xml type syntax to inhibit virschematest from
looking at the schema.
Similar validation for node devices and interfaces is not necessary
since those are referencing system named elements which wouldn't have
the oddly named resource. Also, while it could be checked, avoid the
check for Storage Volumes as there's no way to "inhibit" in the parse
logic algorithm.
This is not for 4.6.0, but figured I'd get it on list for consideration
for 4.7.0. Yes, it's quite unusual and one has to wonder who thinks
up this type of situation, but still in the long run we should attempt
to avoid it anyway. I've only added the extra checking for qemu and
lxc domains, leaving others to those maintainers to choose to utilize.

conf: Disallow new storage pools to use all white space as name

[libvirt] [PATCH RFC 00/39] qemu: Add support for -blockdev
by Peter Krempa
This series adds support for starting and hotplug of disks with
-blockdev/blockdev-add.
Blockjobs are not supported and thus the last patch should not be
applied yet as some refactoring of the jobs is required.
At the beginning of the series there are a few cleanup patches which may
be pushed even at this point.
The main reason this is in RFC state is that block stats reporting does
not work.
The following command:
{"execute":"query-blockstats","arguments":{"query-nodes":true}}
Returns no reasonable data:
{
"stats": {
"flush_total_time_ns": 0,
"wr_highest_offset": 0,
"wr_total_time_ns": 0,
"failed_wr_operations": 0,

"wr_merged": 0,
"wr_bytes": 0,
"timed_stats": [
],
"failed_flush_operations": 0,
"account_invalid": false,
"rd_total_time_ns": 0,
"flush_operations": 0,
"wr_operations": 0,
"rd_merged": 0,

"account_failed": false,

},
"node-name": "libvirt-7-storage"
},
{

},

},
"stats": {
"flush_total_time_ns": 0,

"wr_total_time_ns": 0,

"rd_operations": 0,
"invalid_wr_operations": 0,
"invalid_rd_operations": 0
},
"node-name": "libvirt-7-format"
},
the 'libvirt-7-storage' and 'libvirt-7-format' nodes represent the ISO
backing the CDROM used to boot the VM so reads were executed.
In the old approach when we use -drive and query-nodes is false the
output looks like this:
{
"device": "drive-ide0-0-0",
"parent": {
"stats": {
"flush_total_time_ns": 0,
"wr_highest_offset": 0,
"wr_total_time_ns": 0,
"failed_wr_operations": 0,
"failed_rd_operations": 0,
"wr_merged": 0,
"wr_bytes": 0,
"timed_stats": [
],
"failed_flush_operations": 0,
"account_invalid": false,
"rd_total_time_ns": 0,
"flush_operations": 0,
"wr_operations": 0,
"rd_merged": 0,
"rd_bytes": 0,
"invalid_flush_operations": 0,
"account_failed": false,
"rd_operations": 0,
"invalid_wr_operations": 0,
"invalid_rd_operations": 0
},
"node-name": "#block080"
},
"stats": {
"flush_total_time_ns": 0,
"wr_highest_offset": 0,
"wr_total_time_ns": 0,
"failed_wr_operations": 0,
"failed_rd_operations": 0,
"wr_merged": 0,
"wr_bytes": 0,
"timed_stats": [
],
"failed_flush_operations": 0,
"account_invalid": true,
"rd_total_time_ns": 204236271,
"flush_operations": 0,
"wr_operations": 0,
"rd_merged": 0,
"rd_bytes": 30046628,
"invalid_flush_operations": 0,
"account_failed": true,
"idle_time_ns": 18766797619,
"rd_operations": 14680,
"invalid_wr_operations": 0,
"invalid_rd_operations": 0
},
"node-name": "#block152"
},
I also get all zeroes when I use 'query-nodes' true on a machine started
with -drive.
Without the stats we'd not achieve feature parity unfortunately.
Kevin, could you please have a look?

[libvirt] [PATCH] qemu: Exempt video model 'none' from getting a PCI address on Q35
by Erik Skultety
Commit d48813e8 made sure we wouldn't get one for i440fx, but not for Q35
machine type. If the primary video didn't get the assumed 0:0:1.0 PCI
address, the evaluation then failed with: "Cannot automatically add a
new PCI bus for a device with connect flags 00"
