Commit 501825011c switched the remote driver to using g_auto, but missed
one case of needing to steal a pointer holding the hypervisor type.
Without it, memory is freed and the output of 'virsh version' has random
output
Compiled against library: libvirt 10.0.0
Using library: libvirt 10.0.0
Using API: ��%�U 10.0.0
Running hypervisor: ��U 8.1.3
Ths change also fixes random SIGABRT from perl processes running
libvirt-tck tests.

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
cause. With this change it will now report
error: binary 'virtqemud' does not exist in $PATH: No such file or directory

The generator can produce different code on Linux and macOS:

This is clearly a problem for tests that involve comparing the

In the long run, we need to find a better way to handle this,
