There's no point in skiping the validation step:
- on the source, the VM is parsed for ABI stability checking, thus the
equivalent config was validated when the VM was started
- on the destination, the XML will be validated inside qemuProcessInit
very soon after it is parsed
This fixes problems such as if the user uses a relative path in the disk
source or omits the source, as the disk migration code reasonably
expects that all checks were performed.

DO_TEST_CPUID(arch, host, json) is a multipart test. It consists of the
following tests:
- cpuTestHostCPUID()
- cpuTestGuestCPUID(with JSON_* flag)
- cpuTestCPUIDSignature()
- DO_TEST_JSON():
- if json==JSON_MODELS:
- cpuTestGuestCPUID(without JSON_* flag)
- cpuTestJSONCPUID()
- cputestJSONSignature()
Notice that for tests with json==JSON_MODELS, cpuTestGuestCPUID() is
actually called twice but with different arguments. The first one passes
JSON_MODELS to the test function, while the second one passes 0.
The main difference in behavior when calling cpuTestGuestCPUID() with or
without the flag is that in the first case, it parses the captured qemu
output from $ARCH-cpuid-$CPU.json. It extracts the cpu model list from
that JSON, and uses that to filter out possible cpu models to match.
In other words, it tries to match the cpu to a model that was supported
by the qemu version that was used to generate this JSON file. When it
finds a match, it generates a cpu definition and compares the xml form
of that definition with the file $ARCH-cpuid-$CPU-guest.xml.
When called without the JSON_MODELS flag, it simply attempts to match it
against the full libvirt cpu map and doesn't attempt to filter out any
matches based on the JSON qemu cpu model list. After it finds a match,
it generates an xml definition for the cpu and compares it to the same
file listed above. So if these two invocations disagree on the cpu match
(e.g. because libvirt has added a cpu model to its cpu map that matches
better than one that was supported by the version of qemu that generated
the JSON file) the test will fail.
This duplicate call to cpuTestGuestCPUID() was originally added in
commit 49c945a6f5. The original
justification for that commit was to fix test failures when the Qemu
driver was disabled. But since DO_TEST_JSON() is #defined empty when
qemu is disabled, this particular invocation would not even be executed
in this scenario, so it doesn't seem relevant.

If libvirt is built in client only mode, the libvirtd/virtqemud/etc
daemons won't exist. If the client is told to connect to a local
hypervisor, it'll see the socket doesn't exist, try to spawn the
daemon and then re-try connecting to the socket for a few seconds.
Ultimately this will fail because the daemon doesn't exist and the
user gets an error message
error: Failed to connect socket to '/run/user/1000/libvirt/virtqemud-sock': No such file or directory
technically this is accurate, but it doesn't help identify the root

There are some platforms where 'char' is unsigned, by default
(RPi, s390x to name a few). And because of how test_demo is
written we are experiencing some test cases failing there. For
instance: /xdr/struct-scalar is failing. This is because in the
test (test_struct_scalar()), we have a struct with two chars. One
is initialized to 0xca, the other 0xfe (note that both have the
MSB set). The XDR encoder (xdr_TestStructScalar()) then calls
xdr_char() on both of them. But XDR itself has no notion of
char type, so under the hood, it expands it to int [1] and calls
xdr_int(). And this is where the problem lies. On platforms where
char is signed, the integer expansion results in 0xffffffca, but
on platforms where char is unsigned it results in 0x000000ca. Two
distinct results.
The test then goes and compares the encoded buffer with an
expected one (memcmp(), read from the disk earlier).
This poses no problem for real life use, because when decoding
those chars back, the padding is thrown away.
To avoid tickling this issue, use values that don't have the MSB
set.
