New subject: [PATCH v3 1/5] qemu: add disk post parse to qemublocktest
The post parse callback is part of the real (non-test) processing flow.
This commit adds it (for disks) to the qemublocktest flow as well.
Specifically, this will be needed for tests that use luks encryption,
so that the default encryption engine (which is added in an upcoming commit)
will be overridden by qemu.

Note that this section you've added 'luks2' into is then followed by
sections on each encryption format.
E.g. direct link to the 'luks' section
https://www.libvirt.org/formatstorageencryption.html#StorageEncryptionLuks
You should add a similar section for luks2 outling that it's currently
supported only with librbd2 direct acess and not qcow2 images and
neither the storage driver so that it's clear.
The rest of the patch looks good.

One more thing. We definitely want code in qemu_validate.c rejecting
LUKS2 as encryption format for qcow2 and all others that don't support
it.
Doing it here is too late as this code is called only when starting the
VM, but not when the XML is defined.

This commit extends libvirt XML configuration to support a custom encryption engine.
This means that <encryption format="luks" engine="qemu">
becomes valid.
The only engine for now is qemu. However, a new engine (librbd) will be added in an
upcoming commit.
If no engine is specified, qemu will be used (assuming qemu driver is used).

The only engine for now is qemu. However, a new engine (librbd) will be added in an

If no engine is specified, qemu will be used (assuming qemu driver is used).

Should I create a new file
e.g. tests/qemuxml2xmloutdata/disk-nvme-content.xml
and point the disk-nvme.xml symlink to it?
No just keep symlinks as symlinks. You are not changing anything that
would warant a change to full output file. Namely if the output file is
a symlink to the input file, then the change to the input file should be
sufficient as the output file is the same one.

But that means changing the input file from using the default
engine, to
using "qemu" explicitly.
I was thinking that keeping the input xml unchanged gets a stronger test,
since it also checks that default uses qemu.
I think there's plenty of those. You are also adding one yourself in the
last patch.
Also since most users will still not use the new engine property,
so
keeping the input xml unchanged also tests the more common workload.
That's happening in some of the other tests. There's no need to change
it everywhere.
For the two files which use symlinks just keep them as they are.

Same note as with previous patch. this will need code in qemu_validate.c
rejecting non-qemu backend for stuff which doesn't support it.
Use a switch statement, with a correct type so that the complier forces
any new additions to the enum to be included in the validation code.
