This addition, however, requires some refactoring to be done. First of
all, to match the best practice we should detach the device prior
resetting it. That's why testVirPCIDeviceDetach is detaching all devices
within 0000:00:01.0 and 0000:00:03.0 range. Then, the brand new test
will reset the 0000:00:02.0 device, so the last testVirPCIDeviceReattach
can reattach all the devices back.
In order to perform a PCI device reset, the dummy config file is not
sufficient anymore and must be replaced with real PCI config (binary
mess). Such config files are to be stored under tests/virpcitestdata/
and ought to have '.config' suffix.

In the pci_driver_new function it is possible to set a list of
<vendor:device> IDs that the driver knows. These IDs are passed as
variable arguments and are processed the usual way using va_start() and
va_arg(). However, after all arguments has been processed, we should
call va_end() what we aren't currently doing.

This commit introduces yet another test under virpcitest:
virPCIDeviceDetach. However, in order to be able to do this, the
virpcimock needs to be extended to model the kernel behavior on PCI
device binding and unbinding (create 'driver' symlinks under the device
tree, check for device ID in driver's ID table, etc.)

Currently, if access(path, mode) is invoked, we check if @path has this
special prefix SYSFS_PREFIX. If it does, we modify the path a bit and
call realaccess. If it doesn't we act just like a wrapper and call
realaccess directly. However, we are mocking fopen() as well. And as one
can clearly see there, fopen("/proc/cgroups") will succeed. Hence, we
have an error in our mocked access(): We need to check whether @path is
not equal to /proc/cgroups as it may not exists on real system we're
running however we definitely know how to fopen() it.

As stated in the comment above introduction of the lv_abs_top_builddir
variable, older automake doesn't provide abs_top_builddir variable.
Hence, we are creating our own one with lv_ prefix. However, when
exporting env variables to the tests, the variables are not evaluated
but only substituted. Hence:
LIBVIRT_DRIVER_DIR="$(abs_top_builddir)/src/.libs"
is set to "/src/.libs" with old automake (even though we *think* we've

The vmx file parsing code was reporting errors when parsing floppy.fileName
entries if the filename didn't end in .flp. There is no such restriction in
ESX; even using the GUI to configure floppy filenames you can specify any
arbitrary file with any extension.
Fix by changing the vmx parsing code so that it uses the floppy.fileType
value to determine whether floppy.fileName refers to a block device or a
regular file.
Also remove code that would have generated an error if no floppy.fileName
was specified. This is not an error either.
Updated the floppy tests in vmx2xmltest.c and xml2vmxtest.c.

one case (virHashSearch), we actually strip const away - we aren't
modifying the contents of the table, so much as associated data
for ensuring that the code uses the table correctly (if this were

Prefer using VFIO (if available) to the legacy KVM device passthrough.
With this patch a PCI passthrough device without the driver configured
will be started with VFIO if it's available on the host. If not legacy
KVM passthrough is checked and error is reported if it's not available.
Since 76b644c when the support for RAM filesystems was introduced,
libvirt accepted the following XML:
<source usage='1024' unit='KiB'/>
This was parsed correctly and internally stored in bytes, but it
was formatted as (with an extra 's'):
<source usage='1024' units='KiB'/>
When read again, this was treated as if the units were missing,
meaning libvirt was unable to parse its own XML correctly.
The usage attribute was documented as being in KiB, but it was not
scaled if the unit was missing. Transient domains still worked,
because this was balanced by an extra 'k' in the mount options.
This patch:
Changes the parser to use 'units' instead of 'unit', as the latter
was never documented (fixing persistent domains) and some programs
(libvirt-glib, libvirt-sandbox) already parse the 'units' attribute.
Removes the extra 'k' from the tmpfs mount options, which is needed
because now we parse our own XML correctly.
Changes the default input unit to KiB to match documentation, fixing:
https://bugzilla.redhat.com/show_bug.cgi?id=1015689
The following XML is the recommended default clock configuration for
qemu:
<clock offset='utc'>
<timer name='rtc' tickpolicy='catchup'/>
<timer name='pit' tickpolicy='delay'/>
<timer name='hpet' present='no'/>
</clock>
However we weren't testing any of those timer elements.
The test case average timing code has not been used by any test
case ever. Delete it to remove complexity.

The current OOM test impl is too inefficient to be used on the
large test suites. It loops running 'main' multiple times, once
for each alloc in the 'main' method. This has complexity
'n * (n + 1) / 2' in terms of total alloc count. It will be
replaced by a more efficient impl whicih runs individual test
cases instead. This will have same complexity but the values
of 'n' will be much smaller, so a net win.

I tried to test ./configure --without-lxc --without-remote.
First, the build failed with some odd errors, such as an
inability to build xen, or link failures for virNetTLSInit.
But when you think about it, once there is no remote code,
all of libvirtd is useless, any stateful driver that depends
on libvirtd is also not worth compiling, and any libraries
used only by RPC code are not needed. So I patched
configure.ac to make for some saner defaults when an
explicit disable is attempted. Similarly, since we have
migrated virnetdevbridge into generic code, the workaround
for Linux kernel stupidity must not depend on stateful
drivers being in use.
Then there's 'make check' that needs segregation.
Wow - quite a bit of cleanup to make --without-remote useful :)
* configure.ac: Let --without-remote toggle defaults on stateful
drivers and other libraries. Pick up Linux kernel workarounds
even when qemu and lxc are not being compiled.

Join the worker thread no matter if it is running or zombie already.
With current implementation the thread is joined iff @running is true.
However, when worker executes the last line, @running is set to false.
Hence qemuMonitorTestFree() won't join it (and free resources) even
though we can clearly see worker has run (nobody else sets @running =

Right now, we are testing qemuMonitorSystemPowerdown instead of
qemuMonitorJSONSystemPowerdown. It makes no harm, as both functions have
the same header and the former is just a wrapper over the latter. But we
should be consistent as we're testing the JSON functions only in here.
