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.

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).

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.

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.

Edid support was added with Qemu 5. Windows guests seem to not be able
to get all possible resolutions if the default std VGA device is used as
GPU and the VM boots in BIOS mode. The result is that only one of the
following three resolutions can be configured:
800x600
1024x768
1920x1080
It is important to note that just booting a Windows VM with the edid=off
parameter will not make the large list of resolutions available. It
seems that Windows is caching the list of possible resolutions
somewhere [0].
Uninstalling the 'Microsoft Basic Display Adapter' in the device manager
and rebooting the VM is one way I found to force Windows to recreate the
list of possible resolutions.

on storages where the minimum size of images is bigger than the real
OVMF_VARS.fd file, they get padded to their minimum size
when using such an image, qemu maps it fully to the vm, but the efi
does not find the vars region and creates a file on the first efi
partition it finds
this breaks some settings in the ovmf, such as resolution
to fix this, we have to specify the size for the pflash, so that
qemu only maps the first n bytes in the vm (this only works for
raw files, not for qcow2)
we also have to use the correct size when converting between storages
in 'clone_disk' (used for move disk and cloning vms) and when
live migrating to different storages
when we now expect that the source image is always correctly used/created
(e.g. raw with size=x in pflash argument) then we always create the
target correctly
when encountering users which have a non-valid image (e.g. a efidisk
moved from zfs to qcow2 before this patch), we have to tell them to
recreate the efidisk and the settings on it
we have to version_guard it to 4.1+pve2 (since we haven't bumped yet
since the change to pve2)

Some of the recent QMP changes require at least 2.8.0, but since the
oldest version we officially package for 6.x is 4.0.0 anyway, checking
for at least 3.0 should not break anyone's setup.

installed QEMU binary version.

The previously introduced approach can fail for pinned versions when a
new QEMU release is introduced. The saner approach is to use a mapping
that gives one pve-version for each QEMU release.
Fortunately, the old system has not been bumped yet, so we can still
change it without too much effort.
QEMU versions without a mapping are assumed to be pve0, 4.1 is mapped to
pve1 since thats what we had as our default previously.
Pinned machine versions (i.e. pc-i440fx-4.1) are always assumed to be
pve0, for specific pve-versions they'd have to be pinned as well (i.e.
pc-i440fx-4.1+pve1).
The new logic also makes the pve-version dynamic, and starts VMs with
the lowest possible 'feature-level', i.e. if a feature is only available
with 4.1+pve2, but the VM isn't using it, we still start it with
4.1+pve0.
We die if we don't support a version that is requested from us. This
allows us to use the pve-version as live-migration blocks (i.e. bumping
the version and then live-migrating a VM which uses the new feature (so
is running with the bumped version) to an outdated node will present the
user with a helpful error message and fail instead of silently modifying
the config and only failing *after* the migration).
$version_guard is introduced in config_to_command to use for features
that need to check pve-version, it automatically handles selecting the
newest necessary pve-version for the VM.
Tests have to be adjusted, since all of them now resolve to pve0 instead
of pve1. EXPECT_ERROR matching is changed to use 'eq' instead of regex
to allow special characters in error messages.

if the user set a device as hostpci with the 'shorthand' syntax:
hostpciX: 00:12
we ignored it on starting and showcmd and continued.
Since the user explicitly wanted to passthrough a device, we now check
if there is actually a device with that id
for explicitly configured devices (00:12.1), we did not check if it exists,
but the kvm call failed with a non-obvious error message
now we always call 'lspci' from SysFSTools to check if it actually exists,
and fail if not. With this, we can drop the workaround for adding
'0000' if no domain was given, since lspci does it already for us
this fixes#2510, an issue with using mediated devices where the users did not have
the domain in the config, since we forgot to add the default domain there
the only issue with this patch is that it changes the behaviour of
'showcmd' slightly, as in now, we die if the device was explicitly
given, but did not exists (we showed the commandline, now we fail)
this also slightly changes the commandline for qemu (adding always
the domain), which is not a problem since we cannot live migrate
or snapshot such vms, but we have to adapt the tests

With our QEMU 4.1.1 package we can pass a additional internal version
to QEMU's machine, it will be split out there and ignored, but
returned on a QMP 'query-machines' call.
This allows us to use it for increasing the granularity with which we
can roll-out HW layout changes/additions for VMs. Until now we
required a machine version bump, happening normally every major
release of QEMU, with seldom, for us irrelevant, exceptions.
This often delays rolling out a feature, which would break
live-migration, by several months. That can now be avoided, the new
"pve-version" component of the machine can be bumped at will, and
thus we are much more flexible.
That versions orders after the ($major, $minor) version components
from an stable release - it can thus also be reset on the next
release.
The implementation extends the qemu-machine REGEX, remembers
"pve-version" when doing a "query-machines" and integrates support
into the min_version and extract_version helpers.
We start out with a version of 1.

QMP and monitor helpers are moved from QemuServer.pm.
By using only vm_running_locally instead of check_running, a cyclic
dependency to QemuConfig is avoided. This also means that the $nocheck
parameter serves no more purpose, and has thus been removed along with
vm_mon_cmd_nocheck.
Care has been taken to avoid errors resulting from this, and
occasionally a manual check for a VM's existance inserted on the
callsite.
Methods have been renamed to avoid redundant naming:
* vm_qmp_command -> qmp_cmd
* vm_mon_cmd -> mon_cmd
* vm_human_monitor_command -> hmp_cmd
mon_cmd is exported since it has many users. This patch also changes all
non-package users of vm_qmp_command to use the mon_cmd helper. Includes
mocking for tests.
