The virshtest program testPipeFeeder method is doing this:
mkfifo("test.fifo", 0600) ;
int fd = open("test.fifo", O_RDWR);
char buf[...];
memset(buf, 'a', sizeof(buf));
write(fd, buf, sizeof(buf)) == sizeof(buf));
close(fd);
while the the 'virsh' child process then ends up doing:
fd = open("test.fifo", O_RDONLY);
read(fd, buf, sizeof(buf)) == sizeof(buf));
close(fd);
The 'virsh' code hangs on open() on at least ppc64 and some other
arches. It can be provoked to hang even on x86 by reducing the size of
the buffer. It can be prevented from hanging on ppc64 by increasing the
size of the buffer.
What is happening is a result of differing page sizes, altering the
overall pipe capacity size, since pipes on linux default to 16 pages
in size and thus have architecture specific capacity when measured
in bytes.
* On x86, testPipeFeeder opens R+W, tries to write 140kb and
write() blocks because the pipe is full. This gives time for
virsh to start up, and it can open the pipe for O_RDONLY
since testPipeFeeder still has it open for write. Everything
works as intended.
* On ppc64, testPipeFeeder opens R+W, tries to write 140kb
and write() succeeds because the larger 64kb page size
resulted in greater buffer capacity for the pipe. It thus
quickly closes the pipe, removing the writer, and triggering
discard of all the unread data. Now virsh starts up, tries
to open the pipe for O_RDONLY and blocks waiting for a new
writer to open it, which will never happen. Meson kills
the test after 30 seconds.
NB, every now & then, it will not block because virsh starts
up quickly enough that testPipeFeeder has not yet closed the
write end of the pipe, giving the illusion of correctness.
The key flaw here is that it should not have been using O_RDWR
in testPipeFeeder. Synchronization is required such that both
virsh and testPipeFeeder have their respective ends of the pipe
open before any data is sent. This is trivially arranged by
using O_WRONLY in testPipeFeeder.

The mpx feature was removed from the corresponding qemu cpu models.
With mpx in the libvirt cpu models, libvirt believes the feature
to be implicitly enabled when creating qemu VMs, while in fact it is
disabled.
This became an issue when commit 94eacd5a5f introduced new vmx-*
features, of which some are dependent on mpx (see "feature_dependencies"
table in qemu target/i386/cpu.c), e.g. vmx-exit-clear-bndcfgs and
vmx-entry-load-bndcfgs. These features cannot be enabled by qemu
without also mpx being enabled, leading to the error message
error: Failed to create domain from testdomain.xml
error: operation failed: guest CPU doesn't match

When using vSPC (Virtual Serial Port Concentrator) in vSphere the actual
address for it is saved in serialX.vspc in which case the
serialX.fileName is most probably something we can't get any useful
information from and we also fail during the parsing rendering any
dumpxml and similar tries unsuccessful.
Instead of parsing the vspc URL with something along the lines of
`virURIParse(vspc ? vspc : fileName)`, which could lead to us reporting
information that is very prune to misuse (the vSPC seemingly has a
protocol on top of the telnet connection; redefining the domain would
change the behaviour; the URL might have a fragment we are not saving;
etc.) or adding more XML knobs to indicate vSPC usage (which we would
not be able to configure; we'd have to properly error out everywhere;
etc.) let's just report dummy serial port that leads to nowhere (i.e.

Commit v10.0.0-265-ge67bca23e4 added a `active_config` and
`defined_config` to nodedev mdev internal XML handling.
`defined_config` can be filled at XML parse time, but `active_config`
must be filled in by nodedev driver. This wasn't implemented for the
test driver however, which caused virt-manager test suite regressions.
Working example:
```
$ virsh --connect test:///home/crobinso/src/virt-manager/tests/data/testdriver/testdriver.xml nodedev-dumpxml mdev_8e37ee90_2b51_45e3_9b25_bf8283c03110

<parent>css_0_0_0023</parent>
<capability type='mdev'>
<type id='vfio_ccw-io'/>

```
Broken example:
```
$ virsh --connect test:///home/crobinso/src/virt-manager/tests/data/testdriver/testdriver.xml nodedev-dumpxml mdev_8e37ee90_2b51_45e3_9b25_bf8283c03110

There are PCI devices with pretty large non-prefetchable memory,

Memory at 9d800000 (64-bit, non-prefetchable) [size=8M]
Memory at a6800000 (64-bit, non-prefetchable) [size=16K]
For cold plugged devices this is not a problem, because firmware
sets PCI controllers in a way that make devices behind them just
work. Problem arises if such PCI device is to be hot plugged.
Since the PCI device wasn't present at cold boot, firmware could
not take it into calculations and the amount of reserved memory
is not sufficient.
Introduce a know that allows users overriding value computed by
FW and thus allow hot plug of such PCI devices.

If path to the build directory contains spaces (e.g. meson setup
'a b') then our mocks don't work. The problem is in glibc where
not just a colon but also a space character is a delimiter for
LD_PRELOAD [1]. Hence, a test using mock tries to preload
something like libvirt.git/a b/libsomethingmock.so which is
interpreted by glibc as two separate strings: "libvirt.git/a",
"b/libsomethingmock.so".
One trick to get around this is to set LD_PRELOAD to just the
shared object file (without path) and let glibc find the mock in
paths specified in LD_LIBRARY_PATH (where only a colon or a
semicolon are valid separators [1]). This can be seen in action
by running say:
LD_DEBUG=libs ./virpcitest

When performing an install, it's common for tooling such as virt-install
to remove the install kernel/initrd once they are successfully booted and
the domain has been redefined to boot without them. After the installation
is complete and the domain is rebooted/shutdown, the DAC and selinux
security drivers attempt to restore labels on the now deleted files. It's
harmles wrt functionality, but results in error messages such as
Mar 08 12:40:37 virtqemud[5639]: internal error: child reported (status=125): unable to stat: /var/lib/libvirt/boot/vir>

Add a check for file existence to the virSecurity*RestoreFileLabel functions,
and avoid relabeling if the file is no longer available. Skipping the restore
caused failures in qemusecuritytest, which mocks stat, chown, etc as part of
ensuring the security drivers properly restore labels. virFileExists is now
mocked in qemusecuritymock.c to return true when passed a file previously
seen by the mocked stat, chown, etc functions.
