548ba43028 qemu: remove test for allowing ide controller in s390, rename usb tests
Back in 2013, commit 877bc089 added in some tests that made sure no
error was generated on a domain definition that had an automatically
added usb controller if that domain didn't have a PCI bus to attach
the usb controller to. This was done because, at that time, libvirt
was automatically adding a usb controller to *any* domain definition
that didn't have one.  Along with permitting the controller, two
s390-specific tests were added to ensure this behavior was maintained
- one with <controller type='usb' model='none'/> and another (called
"s390-piix-controllers") that had both usb and ide controllers, but
nothing attached to them.

Then in February of this year, commit 09ab9dcc eliminated the annoying
auto-adding of a usb device for s390 and s390x machines, stating:

 "Since s390 does not support usb the default creation of a usb
  controller for a domain should not occur."

Although, as verified here, the s390 doesn't support usb, and usb
controllers aren't currently added to s390 domain definitions
automatically, there are likely still some domain definitions in the
wild that have a usb controller (which was added *by libvirt*, not by
the user), so we will keep the tests verifying that behavior for
now. But this patch changes the names of the tests to reflect that
they don't actually contain a valid s390 config; this way future
developers won't propagate the incorrect idea that an s390 virtual
machine can have a USB (or IDE) bus.

In the case of the IDE controller, though, libvirt has never
automatically added an IDE controller unless a user added an IDE disk
(which itself would have caused an error), and we specifically *do*
want to begin generating an error when someone tries to add an IDE
controller to a domain that can't support one. For that reason, while
renaming the sz390-piix-controllers patch, this patch removes the
<controller type='ide'...> from it (otherwise the upcoming patch would
break make check)

0260506c65 qemu: use controller alias when constructing device/controller args
This makes sure that that the commandlines generated for devices and
controller devices are all using the alias that has been set in the
controller's object as the id of the controller, rather than
hardcoding a printf (or worse, encoding exceptions to the standard
${controller}${index} into the logic)

Since this "fixes" the controller name used for the sata controller,
the commandline arg for the sata controller in the sata test case had
to be adjusted to be "sata0" instead of "ahci0". All other tests
remain unchanged, verifying that the patch causes no other functional
change.

Because the function that finds a controller alias based on a device
def requires a pointer to the full domainDef in order to get the list
of controllers, the arglist of a few functions had to have this added.

8910e063db caps: Fix regression defaulting to host arch
My commit 747761a79 (v1.2.15 only) dropped this bit of logic when filling
in a default arch in the XML:

-    /* First try to find one matching host arch */
-    for (i = 0; i < caps->nguests; i++) {
-        if (caps->guests[i]->ostype == ostype) {
-            for (j = 0; j < caps->guests[i]->arch.ndomains; j++) {
-                if (caps->guests[i]->arch.domains[j]->type == domain &&
-                    caps->guests[i]->arch.id == caps->host.arch)
-                    return caps->guests[i]->arch.id;
-            }
-        }
-    }

That attempt to match host.arch is important, otherwise we end up
defaulting to i686 on x86_64 host for KVM, which is not intended.
Duplicate it in the centralized CapsLookup function.

Additionally add some testcases that would have caught this.

fd74e23175 tests: Remove redundant aarch64 tests
My commit 7b9de914 added some aarch64 CPU test cases. I wanted to test
two different code paths but inadvertently added two of the same test
cases.

The second code path (using <cpu><model>host</model</cpu>) isn't easily
exercised via the qemu tests anyways, I'll need to look elsewhere.

Regardless, remove the redundant tests for now

dcbedfa672 test: Fix actual vs. expected in virtTestCompareFiles
Commit ca329299 added a utility function virtTestCompareFiles() to
eliminate repetitive code in several test programs. It unfortunately
calls virtTestDifference() with the arguments in the wrong order -
strcontent is the "actual" output gathered by the test rig, while
filecontent is the "expected", and virtTestDifference() wants expected
(filecontent) followed by actual (strcontent), but
virtTestCompareFiles() does the opposite, which can make the output a
bit confusing when there is a failure.

8d4614a512 qemu: Use domain iothreadids to IOThread's 'thread_id'
Add 'thread_id' to the virDomainIOThreadIDDef as a means to store the
'thread_id' as returned from the live qemu monitor data.

Remove the iothreadpids list from _qemuDomainObjPrivate and replace with
the new iothreadids 'thread_id' element.

Rather than use the default numbering scheme of 1..number of iothreads
defined for the domain, use the iothreadid's list for the iothread_id

Since iothreadids list keeps track of the iothread_id's, these are
now used in place of the many places where a for loop would "know"
that the ID was "+ 1" from the array element.

The new tests ensure usage of the <iothreadid> values for an exact number
of iothreads and the usage of a smaller number of <iothreadid> values than
iothreads that exist (and usage of the default numbering scheme).

615bdfda07 rng: fix port number range validation
The PortNumber data type is declared to derive from 'short'.
Unfortunately this is an signed type, so validates the range
[-32,768, 32,767] which excludes valid port numbers between
32767 and 65535.

We can't use 'unsignedShort', since we need -1 to be a valid
port number too.

This change is to use 'int' and set an explicit max boundary
instead of relying on the data types' built-in max.

One of the existing tests is changed to use a high port number
to validate the schema.

* xml -> xml output of virtio-auto

Midonet is an opensource virtual networking that over lays the IP

This patch, defines the schema and documentation that will serve
as basis for the follow up patches that will add support to libvirt
for using Midonet virtual ports for its interfaces. The schema
definition requires that the port profile expresses its interfaceid
as part of the port profile. For that reason, this is part of the

0977b8aa07 domifaddr: Implement the API for qemu
By querying the qemu guest agent with the QMP command
"guest-network-get-interfaces" and converting the received JSON
output to structured objects.

Although "ifconfig" is deprecated, IP aliases created by "ifconfig"
are supported by this API. The legacy syntax of an IP alias is:
"<ifname>:<alias-name>". Since we want all aliases to be clubbed
under parent interface, simply stripping ":<alias-name>" suffices.
Note that IP aliases formed by "ip" aren't visible to "ifconfig",
and aliases created by "ip" do not have any specific name. But
we are lucky, as qemu guest agent detects aliases created by both.

4bca6192f2 conf: Make specifying <memory> optional
Now that the size of guest's memory can be inferred from the NUMA
configuration (if present) make it optional to specify <memory>
explicitly.

To make sure that memory is specified add a check that some form of
memory size was specified. One side effect of this change is that it is
no longer possible to specify 0KiB as memory size for the VM, but I
don't think it would be any useful to do so. (I can imagine embedded
systems without memory, just registers, but that's far from what libvirt
is usually doing).

Forbidding 0 memory for guests also fixes a few corner cases where 0 was
not interpreted correctly and caused failures. (Arguments for numad when
using automatic placement, size of the balloon). This fixes problems
described in https://bugzilla.redhat.com/show_bug.cgi?id=1161461

behave correctly.

cf521fc8ba memtune: change the way how we store unlimited value
There was a mess in the way how we store unlimited value for memory
limits and how we handled values provided by user.  Internally there
were two possible ways how to store unlimited value: as 0 value or as
VIR_DOMAIN_MEMORY_PARAM_UNLIMITED.  Because we chose to store memory
limits as unsigned long long, we cannot use -1 to represent unlimited.
It's much easier for us to say that everything greater than
VIR_DOMAIN_MEMORY_PARAM_UNLIMITED means unlimited and leave 0 as valid
value despite that it makes no sense to set limit to 0.

Remove unnecessary function virCompareLimitUlong.  The update of test
is to prevent the 0 to be miss-used as unlimited in future.

8eb907b8d0 schema: Fix interface link state schema
In commit edd1295e1d I've introduced an
XML element that allows to configure state of the network interface
link. Somehow the RNG schema hunk ended up in a weird place in the
network schema definition. Move it to the right place and add a test
case.

Note that the link state is set up via the monitor at VM startup so I
originally didn't think of adding a test case.

e0e290552b disk: Disallow duplicated target 'dev' values
https://bugzilla.redhat.com/show_bug.cgi?id=1142631

This patch resolves a situation where the same "<target dev='$name'...>"
can be used for multiple disks in the domain.

While the $name is "mostly" advisory regarding the expected order that
the disk is added to the domain and not guaranteed to map to the device
name in the guest OS, it still should be unique enough such that other
domblk* type operations can be performed.

Without the patch, the domblklist will list the same Target twice:

$ virsh domblklist $dom
Target     Source
------------------------------------------------
sda        /var/lib/libvirt/images/file.qcow2
sda        /var/lib/libvirt/images/file.img

Additionally, getting domblkstat, domblkerror, domblkinfo, and other block*
type calls will not be able to reference the second target.

Fortunately, hotplug disallows adding a "third" sda value:

$ qemu-img create -f raw /var/lib/libvirt/images/file2.img 10M
$ virsh attach-disk $dom /var/lib/libvirt/images/file2.img sda
error: Failed to attach disk
error: operation failed: target sda already exists

$

BUT, it since 'sdb' doesn't exist one would get the following on the same
hotplug attempt, but changing to use 'sdb' instead of 'sda'

$ virsh attach-disk $dom /var/lib/libvirt/images/file2.img sdb
error: Failed to attach disk
error: internal error: unable to execute QEMU command 'device_add': Duplicate ID 'scsi0-0-1' for device

$

Since we cannot fix this issue at parsing time, the best that can be done so
as to not "lose" a domain is to make the check prior to starting the guest
with the results as follows:

$ virsh start $dom
error: Failed to start domain $dom
error: XML error: target 'sda' duplicated for disk sources '/var/lib/libvirt/images/file.qcow2' and '/var/lib/libvirt/images/file.img'

$

Running 'make check' found a few more instances in the tests where this
duplicated target dev value was being used. These also exhibited some
duplicated 'id=' values (negating the uniqueness argument of aliases) in
the corresponding .args file and of course the *xmlout version of a few
input XML files.

4bbe1029f2 qemu: fix ifindex array reported to systemd
Commit f7afeddc added code to report to systemd an array of interface
indexes for all tap devices used by a guest. Unfortunately it not only
didn't add code to report the ifindexes for macvtap interfaces
(interface type='direct') or the tap devices used by type='ethernet',
it ended up sending "-1" as the ifindex for each macvtap or hostdev
interface. This resulted in a failure to start any domain that had a
macvtap or hostdev interface (or actually any type other than
"network" or "bridge").

This patch does the following with the nicindexes array:

1) Modify qemuBuildInterfaceCommandLine() to only fill in the
nicindexes array if given a non-NULL pointer to an array (and modifies
the test jig calls to the function to send NULL). This is because
there are tests in the test suite that have type='ethernet' and still
have an ifname specified, but that device of course doesn't actually
exist on the test system, so attempts to call virNetDevGetIndex() will
fail.

2) Even then, only add an entry to the nicindexes array for
appropriate types, and to do so for all appropriate types ("network",
"bridge", and "direct"), but only if the ifname is known (since that
is required to call virNetDevGetIndex().

af20423264 virQEMUCapsCacheLookupCopy: Filter qemuCaps based on machineType
Not all machine types support all devices, device properties, backends,
etc. So until we create a matrix of [machineType, qemuCaps], lets just
filter out some capabilities before we return them to the consumer
(which is going to make decisions based on them straight away).
Currently, as qemu is unable to tell which capabilities are (not)
enabled for given machine types, it's us who has to hardcode the matrix.
One day maybe the hardcoding will go away and we can create the matrix
dynamically on the fly based on a few monitor calls.

7832fac847 qemuBuildMemoryBackendStr: Report backend requirement more appropriately
So, when building the '-numa' command line, the
qemuBuildMemoryBackendStr() function does quite a lot of checks to
chose the best backend, or to check if one is in fact needed. However,
it returned that backend is needed even for this little fella:

  <numatune>
    <memory mode="strict" nodeset="0,2"/>
  </numatune>

This can be guaranteed via CGroups entirely, there's no need to use
memory-backend-ram to let qemu know where to get memory from. Well, as
long as there's no <memnode/> element, which explicitly requires the
backend. Long story short, we wouldn't have to care, as qemu works
either way. However, the problem is migration (as always). Previously,
libvirt would have started qemu with:

  -numa node,memory=X

in this case and restricted memory placement in CGroups. Today, libvirt
creates more complicated command line:

  -object memory-backend-ram,id=ram-node0,size=X
  -numa node,memdev=ram-node0

Again, one wouldn't find anything wrong with these two approaches.
Both work just fine. Unless you try to migrated from the older libvirt
into the newer one. These two approaches are, unfortunately, not
compatible. My suggestion is, in order to allow users to migrate, lets
use the older approach for as long as the newer one is not needed.
