4c33c5568c qemu: checkpoint: Don't merge checkpoints during deletion
Now that we've switched to the simple handling, the first thing that can
be massively simplified is checkpoint deletion. We now need to only go
through the backing chain and find the appropriately named bitmaps and
delete them, no complex lookups or merging.

Note that compared to other functions this deletes the bitmap in all
layers compared to others where we expect only exactly 1 bitmap of a
name in the backing chain to prevent potential problems.

As the changes are going to be incompatible with any current test data
remove all test cases for bitmap handling during checkpoint deletion,

operations.

The tests will be gradually added back later after the code and

201bd5db63 qemu: Fill default value in //cpu/@migratable attribute
Before QEMU introduced migratable CPU property, "-cpu host" included all
features that could be enabled on the host, even those which would block
migration. In other words, the default was equivalent to migratable=off.
When the migratable property was introduced, the default changed to
migratable=on. Let's record the default in domain XML.

69daa2ea8a testCompareXMLToArgvValidateSchema: Construct @vm from scratch
Currently, the @vm is passed in as an argument and
testCompareXMLToArgvCreateArgs() is called over it which means

point where ValidateSchema() is called, the domain object is
already 'prepared', i.e. all device aliases are assigned and so
on. But our code is not prepared to 'prepare' a domain twice - it
simply overwrites all the pointers leading to a memory leak.

Fortunately, this is only the problem of this test.

6bde2a1e20 conf: Sanitize handling of <auth> and <encryption> placement for disks
Modern way to store <auth> and <encryption> of a <disk> is under
<source>. This was added to mirror how <backingStore> handles these and
in fact they are relevant to the source rather than to any other part of
the disk. Historically we allowed them to be directly under <disk> and
we need to keep compatibility.

This wasn't a problem until introduction of -blockdev in qemu using of
<auth> or <encryption> plainly wouldn't work with backing chains.

Now that it works in backing chains and can be moved back and forth
using snapshots/block-commit we need to ensure that the original
placement is properly kept even if the source changes.

To achieve the above semantics we need to store the preferred placement
with the disk definition rather than the storage source definitions and
also ensure that the modern way is chosen when the VM started with
<source/encryption> only in the backing store.

b40ec75296 qemu: Forbid non-raw images for disk type='lun' with vitio-blk frontend
Historically the virtio-blk frontend by default enabled SCSI emulation
and tried to do SCSI command passthrough. As this was enabled by default
there's a fallback mechanism in place in cases when the backend doesn't
support SCSI for any reason.

This is not the case when disk type=lun is used with 'scsi-block' via
'virtio-scsi'.

We did not restrict configurations when the user picks 'qcow2' or any
other format as format of the disk, in which case the emulation is
disabled as such configuration doesn't make sense.

This patch unifies the approach so that 'raw' is required both when used
via 'virtio-blk' and 'virtio-scsi' so that the user is presented with
the expected configuration. Note that use of <disk type='lun'> is
already very restrictive as it requires a block device or iSCSI storage.

Additionally the scsi emulation is now deprecated by qemu with
virtio-blk as it conflicts with virtio-1 and the alternative is to use
'virtio-scsi' which performs better and is along for a very long time.

Starting from QEMU-5.0 the 'scsi' property was also deprecated. There
replacement for the functionality is to use 'virtio-scsi' for the
purpose. This isn't a direct replacement though.

Add capability named QEMU_CAPS_VIRTIO_BLK_SCSI_DEFAULT_DISABLED which
allows us to stop formatting the 'scsi=' property if it's disabled by
default and not requested so that we don't use deprecated features.

3bcbdc51da qemu: process: Don't clear QEMU_CAPS_BLOCKDEV when SD card is present
Help QEMU in deprecation of -drive if=none without the need to refactor
all old boards. Stop masking out -blockdev support when -drive if=sd
needs to be used. We achieve this by forbidding blockjobs and
special-casing all other code paths. Blockjobs are sacrificed in this
case as SD cards are a corner case for some ARM boards and are thus not
used commonly.

2e93af279a Revert "tests: Use qemu:///embed to simplify fakerootdir management"
Turns out that it's not enough to pass the qemu:///embed root to
virQEMUDriverConfigNew(), you also have to make sure the same
string is copied into the virQEMUDriver structure yourself, and
not doing so in our case resulted in the cleanup never happening
and in distcheck failing because of that.

On the other hand, actually setting config->embeddedRoot would
result in different paths being generated for each test run, which
would obviously break qemuxml2argvtest, so that's not an option
either.

a0a2c8ab73 qemu: Add capability for CFPC pSeries feature
CFPC (Cache Flush on Privilege Change) is one of the capabilities
added to QEMU to mitigate Spectre vulnerabilities in Power chips.
It was implemented in QEMU 2.12 by commit 6898aed77f46.

This capability is still used today due to differences in how
the host setup (hardware and firmware/kernel) can handle this
mitigation. Its default value also varies with the pseries machine
version of the time. There's also certain OSes, like AIX, that
might not support the default value of the pseries machine the
guest uses.

Exposing this in the Libvirt XML as a feature will allow users to tune
CFPC values in a cleaner way, instead of hacking parameters in
<qemu:commandline> elements.

84a20fe8e3 qemumonitortestutils: Make test monitor failures more prominent
Until now we've tried to report errors from the test monitor code by
passing them back as failures from the qemu we simulate. This doesn't
work well in cases when the monitor logic does not detect failures or
has fallback code. Additionally there isn't much use for continuing the
test execution after first failure as in most cases the test data will
be misaligned and all other calls will fail as well.

To make the errors more obvious this patch moves away from reporting
them via the simulated monitor to reporting them to stderr and
exit()ing afterwards. While this might be less convenient
when developing tests it actually makes failures in the test suite
really obvious and doesn't require any opt-in from the tests themselves.

size buffers.

The test cases validate that some of the corner cases involving colons

unplug timeout as it's guaranteed to be executed in correct order.

According to my testing it shaves off ~450ms of test run:

real	0m0.721s

vs.

real	0m0.259s

2d3cf60328 qemu: hook up pcie-root-port hotplug='off' option
If a pcie-root-port or pcie-downstream-port has hotplug='off' in its
<target> subelement, and if the qemu binary supports the hotplug=false
option, then it will be added to the commandline for the pcie
controller. This controller will then not allow any hotplug/unplug of
devices while the guest is running (and the hotplug capability won't
be advertised to the guest OS, so the guest OS also won't present
unplugging of PCI devices as an option).

  <controller type='pci' model='pcie-root-port'>
    <target hotplug='off'/>
  </controller>

For any PCI controllers other than pcie-downstream-port and
pcie-root-port, of for qemu binaries that don't support the hotplug
commandline option, an error will be logged during validation.

78f4d5e6f1 conf: new attribute "hotplug" for pci controllers
a <controller type='pci'...> element can now have a "hotplug"
attribute in the <target> subelement. This is intended to control
whether or not the slot(s) of the controller support
hotplugging/unplugging a device:

   <controller type='pci' model='pcie-root-port'>
     <target hotplug='off'/>
   </controller>

The default value of hotplug is "on".

Since support for configuring such an option is hypervisor-dependent
(and will vary among different types of PCI controllers even on a
single hypervisor), no validation is done in this patch - that
validation will be done in the patch that wires support for the
setting into the hypervisor.

When generating a path for memory-backend-file or -mem-path, qemu
driver will use the following pattern:

  $memoryBackingDir/libvirt/qemu/$id-$shortName

where $memoryBackingDir defaults to /var/lib/libvirt/qemu/ram but
can be overridden in qemu.conf. Anyway, the "/libvirt/qemu/" part
looks redundant, because it's already contained in the default,
or creates unnecessary nesting if overridden in qemu.conf.

the passed value as prefix for some internal paths (e.g.
cfg->libDir). If it is NULL though, it looks if the other
argument, @privileged is true or false and generates internal
paths accordingly. But when calling the function from the test
suite, instead of passing NULL for @root, an empty string is
passed. Fortunately, this doesn't create a problem because in
both problematic cases the generated paths are "fixed" to point
somewhere into build dir or the code which is tested doesn't

dd17a4eba8 cpu_map: Add more -noTSX x86 CPU models
One of the mitigation methods for TAA[1] is to disable TSX
support on the host system.  Linux added a mechanism to disable
TSX globally through the kernel command line, and many Linux
distributions now default to tsx=off.  This makes existing CPU
models that have HLE and RTM enabled not usable anymore.

Add new versions of all CPU models that have the HLE and RTM
features enabled, that can be used when TSX is disabled in the
host system.

On systems disabling the features without those types defined
in cpu-maps users end up without modern CPU types in the list
of usable CPUs to use in the likes of virsh domcapabilities
or tools higher in the stack like virt-manager.

This adds:

be00118d5d util: keep the pidfile locked
Unfortunately, advisory record locking lose the lock if any fd refering
to the file is closed. There doesn't seem to be a way to preserve the
lock atomically. We could eventually retake the lock if low pidfilefd
is required.

This fixes processes being leaked, as they are not killed in
virPidFileForceCleanupPath() if the lock can be taken. Here also, we may
consider this is not good enough, as a process may leak by simply
closing the pidfilefd.

Fixes commit d146105f1e ("virCommand:
Actually acquire pidfile instead of just writing it")

d146105f1e virCommand: Actually acquire pidfile instead of just writing it
Our virCommand module allows us to set a pidfile for commands we
want to spawn. The caller constructs the string of pidfile path
and then uses virCommandSetPidFile() to tell the module to write
the pidfile once the command is ran. This usually works, but has
two flaws:

1) the child process does not hold the pidfile open & locked.
Therefore, the caller (or anybody else) can't use our fancy
virPidFileForceCleanupPath() function to kill the command
afterwards. Also, for everybody else on the system it's
needlessly harder to check if the pid from the pidfile is still
alive or not.

2) if the caller ever makes a mistake and passes the same pidfile
path for two different commands, the start of the second command
will overwrite the pidfile even though the first command might
still be running.

NOTE that this temporarily renders some command spawning
unusable, specifically those code patterns where both
virCommandSetPidFile() is used together with instructing spawned
command to acquire pidfile itself. Fortunately, there is only one
occurrence of such pattern and it is in
qemuProcessStartManagedPRDaemon(). This is fixed in next commit.

As a part of c799d150d5 I've introduced a test case that
tests whether passing error object between processes works. The
test spawns a child which reports a system error, parent process
then reads the error and compares with expected output. Problem
with this approach is that error message contains stringified

messages than Linux. Therefore, use g_strerror() to do the errno

Using the 'uuid' element for ppc64 NVDIMM memory added in the
previous patch, use it in qemuBuildMemoryDeviceStr() to pass
it over to QEMU.

Another ppc64 restriction is the necessity of a mem->labelsize,
given than ppc64 only support label-area backed NVDIMMs.

Finally, we don't want ppc64 NVDIMMs to align up due to the
high risk of going beyond the end of file with a 256MiB
increment that the user didn't predict. Align it down
instead. If target size is less than the minimum of
256MiB + labelsize, error out since QEMU will error out
if we attempt to round it up to the minimum.

ppc64 NVDIMM support was implemented in QEMU by commit [1].
The support is similar to what x86 already does, aside from
an extra 'uuid' element.

This patch introduces a new optional 'uuid' element for the
NVDIMM memory model. This element behaves like the 'uuid'
element of the domain definition - if absent, we'll create
a new one, otherwise use the one provided by the XML.
The 'uuid' element is exclusive to pseries guests and are
unavailable for other architectures.

Next patch will use this new element to add NVDIMM support
for ppc64.

4e8faa5cdc qemu: domain: Store data for 'secret' object representing http cookies
The http cookies can have potentially sensitive values and thus should
not be leaked into the command line. This means that we'll need to
instantiate a 'secret' object in qemu to pass the value encrypted.

This patch adds infrastructure for storing of the alias in the status
XML.
