After 78d7c3c5 we are strdup()-ing path to qemu-bridge-helper.
However, the check for its return value is missing. So it is
possible we've ignored the OOM error silently.
Add a "dry run" address allocation to figure out how many bridges
will be needed for all the devices without explicit addresses.
Auto-add just enough bridges to put all the devices on, or up to the
bridge with the largest specified index.
<controller type='pci' index='0' model='pci-root'/>
is auto-added to pc* machine types.
Without this controller PCI bus 0 is not available and
no PCI addresses are assigned by default.
Since older libvirt supported PCI bus 0 even without
this controller, it is removed from the XML when migrating.
Now we set the default disk driver name when parsing
the qemu command line too, hence all the test changes.
Assume format type is 'auto' when none is specified on
qemu command line.
Currently, if there has been an error in building command line
process after virtual interfaces has been created, the flow jumps
to 'error' label, where virDomainConfNWFilterTeardown() is
called. This may report an error as well, but should not
overwrite the original cause why we jumped to 'error' label.
Instead of making a choice between the underscore and camelCase, this
simply changes "num_queues" into "queues", which is also consistent
with Michal's multiple queue support for interface.
Improve error reporting and generating of SPICE command line arguments
according to the need to enable TLS. If TLS is disabled, there's no need
to pass the certificate dir to qemu.

Refactoring done in 19c6ad9ac7 didn't
correctly take into account the order cgroup limit modification needs to
be done in. This resulted into errors when decreasing the limits.
The operations need to take place in this order:
decrease hard limit
change swap hard limit
or
change swap hard limit
increase hard limit
This patch also fixes the check if the hard_limit is less than
swap_hard_limit to print better error messages. For this purpose I
introduced a helper function virCompareLimitUlong to compare limit
values where value of 0 is equal to unlimited. Additionally the check is
now applied also when the user does not provide all of the tunables
through the API and in that case the currently set values are used.

After discussions with systemd developers it was decided that
a better default policy for resource partitions is to have
3 default partitions at the top level
/system - system services
/machine - virtual machines / containers
/user - user login session
This ensures that the default policy isolates guest from
user login sessions & system services, so a mis-behaving
guest can't consume 100% of CPU usage if other things are
contending for it.
Thus we change the default partition from /system to
/machine

Wrong use of the parentheses causes "rc" always having a boolean value,

Each bus is represented as an array of 32 8-bit integers
where each bit represents a PCI function and each byte represents
a PCI slot.
Uses just one bus so far.
Create a new function qemuPCIAddressValidate and call it everywhere
the user might supply an incorrect address:
* qemuCollectPCIAddress for domain definition
* qemuDomainPCIAddressEnsureAddr and ReleaseSlot for hotplug
Slot and function shouldn't be wrong at this point, since values
out of range should be rejected by the XML parser.
Change QEMU_PCI_ADDRESS_LAST_SLOT to the number of slots in the bus,
not the maximum slot value, to match QEMU_PCI_ADDRESS_LAST_FUNCTION
and rename them both to have _LAST at the end.

The recent qemu requires "0x" prefix for the disk wwn, this patch
changes virValidateWWN to allow the prefix, and prepend "0x" if
it's not specified. E.g.
qemu-kvm: -device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,\
drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,wwn=6000c60016ea71ad:
Property 'scsi-hd.wwn' doesn't take value '6000c60016ea71ad'
Though it's a qemu regression, but it's nice to allow the prefix,
and doesn't hurt for us to always output "0x".

The virCgroupNewDriver method had a 'bool privileged' param.

Historically QEMU/LXC guests have been placed in a cgroup layout
that is
$LOCATION-OF-LIBVIRTD/libvirt/{qemu,lxc}/$VMNAME
This is bad for a number of reasons
- The cgroup hierarchy gets very deep which seriously
impacts kernel performance due to cgroups scalability
limitations.
- It is hard to setup cgroup policies which apply across
services and virtual machines, since all VMs are underneath
the libvirtd service.
To address this the default cgroup location is changed to
be
/system/$VMNAME.{lxc,qemu}.libvirt
This puts virtual machines at the same level in the hierarchy
as system services, allowing consistent policy to be setup
across all of them.
This also honours the new resource partition location from the
XML configuration, for example
<resource>
<partition>/virtualmachines/production</partitions>
</resource>
will result in the VM being placed at
/virtualmachines/production/$VMNAME.{lxc,qemu}.libvirt
NB, with the exception of the default, /system, path which
is intended to always exist, libvirt will not attempt to
auto-create the partitions in the XML. It is the responsibility
of the admin/app to configure the partitions. Later libvirt
APIs will provide a way todo this.

To support "shareable" for volume type disk, we have to translate
the source before trying to add the shared disk entry. To achieve
the goal, this moves the helper qemuTranslateDiskSourcePool into
src/qemu/qemu_conf.c, and introduce an internal only member (voltype)
for struct _virDomainDiskSourcePoolDef, to record the underlying
volume type for use when building the drive string.
Later patch will support "shareable" volume type disk.
This adds a new helper qemuTranslateDiskSourcePool which uses the
storage pool/vol APIs to translate the disk source before building
the drive string. Network volume is not supported yet. Disk chain
for volume type disk may be supported later, but before I'm confident
it doesn't break anything, it's just disabled now.
For both "live" and "config" changes of vcpupin and emulatorpin, an

% virsh vcpupin hame

% virsh start hame
error: Failed to start domain hame
error: An error occurred, but the cause is unknown
This introduce a new attribute "num_queues" (same with the good name
QEMU uses) for virtio-scsi controller. An example of the XML:
<controller type='scsi' index='0' model='virtio-scsi' num_queues='8'/>
The corresponding QEMU command line:
-device virtio-scsi-pci,id=scsi0,num_queues=8,bus=pci.0,addr=0x3 \
When setting processor count for a domain using the API libvirt enforced
a maximum processor count, while it isn't enforced when taking the XML path.
This patch removes the check to match the XML.
Currently when getting an instance of virCgroupPtr we will
create the path in all cgroup controllers. Only at the virt
driver layer are we attempting to filter controllers. This
is bad because the mere act of creating the dirs in the
controllers can have a functional impact on the kernel,
particularly for performance.
Update the virCgroupForDriver() method to accept a bitmask
of controllers to use. Only create dirs in the controllers
that are requested. When creating cgroups for domains,
respect the active controller list from the parent cgroup

This patch refactors various places to allow removing of the
defaultConsoleTargetType callback from the virCaps structure.
A new console character device target type is introduced -
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_NONE - to mark that no type was
specified in the XML. This type is at the end converted to the standard
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL. Other types that are
different from this default have to be processed separately in the
device post parse callback.
Use the virDomainXMLConf structure to hold this data and tweak the code
to avoid semantic change.
Without configuration the KVM mac prefix is used by default. I chose it
as it's in the privately administered segment so it should be usable for
any purposes.
Use the qemu specific callback to fill this data in the qemu driver as
it's the only place where it was used and fix tests as the qemu test
capability object didn't configure the defaults for the tests.
This patch removes the emulatorRequired field and associated
infrastructure from the virCaps object. Instead the driver specific
callbacks are used as this field isn't enforced by all drivers.
This patch implements the appropriate callbacks in the qemu and lxc
driver and moves to check to that location.
This patch removes the defaultDiskDriverName from the virCaps
structure. This particular default value is used only in the qemu driver
so this patch uses the recently added callback to fill the driver name
if it's needed instead of propagating it through virCaps.
This patch implements the devices post parse callback and uses it to fill
the default qemu network card model into the XML if none is specified.
Libvirt assumes that the network card model for qemu is the "rtl8139".
Record this in the XML using the new callback to avoid user
confusion.
This patch adds instrumentation that will allow hypervisor drivers to
fill and validate domain and device definitions after parsed by the XML
parser.
With this patch, after the XML is parsed, a callback to the driver is
issued requesting to fill and validate driver specific details of the
configuration. This allows to use sensible defaults and checks on a per
driver basis at the time the XML is parsed.
Two callback pointers are stored in the new virDomainXMLConf object:
* virDomainDeviceDefPostParseCallback (devicesPostParseCallback)
- called for a single device parsed and for every single device in a
domain config. A virDomainDeviceDefPtr is passed along with the
domain definition and virCaps.
* virDomainDefPostParseCallback, (domainPostParseCallback)
- A callback that is meant to process the domain config after it's
parsed. A virDomainDefPtr is passed along with virCaps.
Both types of callbacks support arbitrary opaque data passed for the
callback functions.
Errors may be reported in those callbacks resulting in a XML parsing
failure.
This patch is the result of running:
for i in $(git ls-files | grep -v html | grep -v \.po$ ); do
sed -i -e "s/virDomainXMLConf/virDomainXMLOption/g" -e "s/xmlconf/xmlopt/g" $i
done
and a few manual tweaks.
Commit f84b92ea introduced a memory leak on error; John Ferlan reported
that valgrind caught it during 'make check'.
* src/qemu/qemu_command.c (qemuBuildMachineArgStr): Plug leak.
The JSON generator is able to represent only values less than LLONG_MAX, fix the
bandwidth limit checks when converting to value to catch overflows before they
reach the generator.
Mimic the fix done in 02b9097274 to fix crash by
accessing an already freed structure. Also copy the explaining comment why the
pointer can't be accessed any more.
Format the address using the helper instead of having similar code in
multiple places.
This patch also fixes leak of the MAC address string in
ebtablesRemoveForwardAllowIn() and ebtablesAddForwardAllowIn() in
src/util/virebtables.c
Currently, -machine option is used only when dump-guest-core is set.
To use options defined in machine option for newer version of QEMU,
it needs to use -machine xxx, and to be compatible with older version

version which supports -machine option.
