In most circumstances a pidfd gets closed automatically once the child
dies, and that *should* be guaranteed by us calling SIGKILL - however,
it seems that sometimes that doesn't happen, leading to leaked file
descriptors[0].
Also add a small note to verbose mode showing when the late-cleanup
actually happens, helped during debug.

by fixing a typo. Since cfs_read_file within the storage module was not mocked,
the tests could fail on some setups. Now that get_bandwidth_limit is mocked,
cfs_read_file is not called anymore, but still mock it too for good measure and
to make it more future-proof.

Previously one could specify a CPU flag like 'pcidfoobar' and it would
be accepted, even though we attempt to filter VM-only flags for
security. AFAICT none of the flags we allow can be turned into any
others just by appending text, but better safe than sorry.

by checking if the vm is paused at the beginning and skipping the
resume now we also skip the qga freeze/thaw (which cannot work if the
vm is paused)
moved the 'vm_is_paused' sub from the api to PVE/QemuServer.pm so it
is available everywhere we need it.
since a suspend backup would pause the vm anyway, we can skip that
step also

this was previously covered by the "lets destroy ever disk which
matches the VMID" feature we disarmed a bit.
As unused disks are referenced in the config, it is not subtle to
destroy them (and we always did in the past) so fix that regression
again for explicitly referenced but unused disks.

Since an old change released with a version bump on 2009-09-07, we
search all enabled storages for VMID maching volumes on VM removal
and purge those too.
This has multiple pitfalls and may be quite unexpected for some
users.
It can make problems when:
* on recovery a VM is created, before disks are reattached the admin
notices some settings issues and chooses to just recreate the VM;
but during destroying the dummy VM all related disks get destroyed
unconditionally which may result in data loss. This actually
happened and is the original reason for the decision to change
this.
* a storage is shared between PVE instance (between a set of clusters
and/or single nodes), while this is against our rules it may still
come as a surprise if destroying a VM on node A may destroy
unrelated and unreferenced disks on the unrelated node B without
asking or allowing to avoid that.
As this the removal of matching but unreferenced disks can result in
permanent data loss (up to the last backup) and may be to subtle and
unforgiving, allow to opt-out of it.
In the long run we want to make this opt-in, but that is an API
change and so needs to wait for next major release. But, we can adapt
the GUI already to make it opt-in there, catching most of the cases.
side-note: CT do not have this behavior at all

While the do_import method cleans up the current disk it was
importing on any error the following cases are not handled:
* multiple disks, first few succeed then one fails, only the last
failed one was taken care of before this patch
* error after the import disk loop was not handled

On clone_vm when cloning the disks while the VM is running, we use
drive-mirror. We skip completion until the last disk, but with a
cloudinit disk there's no drive-mirror and so no completion done. If it
is the last disk in the hash, we never complete the drive-mirror jobs
and no further cloning is possible as there are already active jobs
using the disks.
To fix it we have to call qemu_drive_mirror_monitor directly in the case
of cloudinit when completion is requested and there are jobs defined.

by doing it in a local directory instead of /var/lock/pve-manager, which is
used by the installed/non-test PVE code. This also covers the shared case,
which will become relevant after fixing #3229 (currently migration doesn't
touch disks on shared storages).

The phrasing left some room for speculation when this would be triggered.
E.g. after cloning a full VM?
Currently the only instances where it is used is when a disk is moved or
a VM migrated.

It's not easily possible to use separate JSON files for the test configuration,
because part of it is generated with perl code. While this could be encoded too,
it seems cleaner to use the "run a single test by specifing the name"
functionality while adding a way for make to obtain a list of the test names.
Each test has (and needs) its own directory now, meaning the log files do not
need to be renamed anymore.

We only added the format extension when it was not 'raw'. But on file level
storages we always require it. To fix this, always add the format
extension if the storage provides the 'path' property.
This is the same logic we use in create_disks for cloudinit disks.

and the associated parts for 'qm start'.
Each test will first populate the MigrationTest/run directory
with the relevant configuration files and files keeping track of the
state of everything necessary. Second, the mock-script for migration
is executed, which in turn will execute the 'qm start' mock-script
(if it's an online test that gets far enough). The scripts will simulate
a migration and update the relevant files in the MigrationTest/run directory.
Finally, the main test script will evaluate the state.
The main checks are the volume IDs on the source and target and the VM
configuration itself. Additional checks are the vm_status and expected_calls,
keeping track if certain calls have been made.
The rationale behind creating two mock-scripts is two-fold:
1. It removes the need to hard code responses for the tunnel
and to recycle logic for determining and allocating migration volumes.
Some of that logic already happens in the API part, so it was necessary
to mock the whole CLI-Handler.
2. It allows testing the code relevant for migration in 'qm start' as well,
and it should even be possible to test different versions of the
mock-scripts against each other. With a bit of extra work and things
like 'git worktree', it might even be possible to automate this.
The helper get_patched config is useful to change pre-defined configuration
files on the fly, avoiding the new to explicitly define whole configurations to
test for something in many cases.
