See commit 17858a1695 (hw/acpi/ich9: Set ACPI PCI hot-plug as default
on Q35)[0] in upstream QEMU repository for details about why the change
was made.
As that change affects systemds predictable interface naming[1],
e.g., by going from a previously `ens18` name to `enp6s18`, it may
have rather bad effects for users that did not setup some .link files
to enforce a specific naming by an more stable information like the
NIC's MAC-Address
The alternative would be making the preferred mode of hotplug an
option like `hotplug-mode=<acpi|pcie>`, but it does not seems like
one would like to change that much in the first place...
Note the changes to the tests and especially the tests with q35
machines that did not change.

avoids the possibility to die during phase3_cleanup and instead of needing to
duplicate the cleanup ourselves, benefit from phase2_cleanup doing so.
The duplicate cleanup was also very incomplete: it didn't stop the remote kvm
process (leading to 'VM already running' when trying to migrate again
afterwards), but it removed its disks, and it didn't unlock the config, didn't
close the tunnel and didn't cancel the block-dirty bitmaps.
Since migrate_cancel should do nothing after the (non-storage) migrate process
has completed, even that cleanup step is fine here.
Since phase3 is empty at the moment, the order of operations is still the same.

A "savevm" call (both our async variant and the upstream sync one) use
migration code internally. As such, they both expect migration
capabilities to be set.
This is usually not a problem, as the default set of capabilities is ok,
however, it leads to differing snapshot settings if one does a snapshot
after a machine has been live-migrated (as the capabilities will persist
from that), which could potentially lead to discrepencies in snapshots
(currently it seems to be fine, but it still makes sense to set them to
safeguard against future changes).
Note that we do set the "dirty-bitmaps" capability now (if
query-proxmox-support reports true), which has three effects:
1) PBS dirty-bitmaps are preserved in snapshots, enabling
fast-incremental backups to work after rollback (as long as no newer
backups exist), including for hibernate/resume
2) snapshots taken from now on, with a QEMU version supporting bitmap
migration, *might* lead to incompatibility of these snapshots with
QEMU versions that don't know about bitmaps at all (i.e. < 5.0 IIRC?)
- forward compatibility is still given, and all other capabilities we
set go back to very old versions
3) since we now explicitly disable bitmap saving if the version doesn't
report support, we avoid crashes even with not-updated QEMU versions

A fix for violating a important standard for booting[0] in recently
packaged QEMU 5.2 surfaced some issues with Windows based VMs in our
forum[1], which seem to be quite sensitive for such changes (it seems
they derive lots of their device assignment from ACPI).
User visible effects are loss of any network configuration due to
windows thinking it was swapped with a new one, and starts with a
fresh config - this is mostly problematic for setups with static
address assignment.
There may be lots of other, more subtle, effects and the PVE admin is
also not always the VM admin, so we really need to avoid such
negative effects. Do this by pinning the version of any windows based
VMs to either the minimum of (5.1, kvm-version) for existing VMs or
the kvm-version at time of VM creation for new ones.
There are patches in pve-manager for user to be able to change the
pinned version themself in the webinterface, so this can now also get
adapted more easily if there surface any other issues (with new or
old version) in the future.

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

1920x1080
It is important to note that just booting a Windows VM with the edid=off

seems that Windows is caching the list of possible resolutions
somewhere [0].

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.

for explicitly configured devices (00:12.1), we did not check if it exists,

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.

The reason for why we did not do this in the first place was the fact
that the "usb3" flag could be set in older qemu-server versions, we
just ignored it but not filtered it out of the config..
That means there can be VMs out there which would now become a
different HW layout, and issue for migration and live-snapshot
restore.
But, actually, while the "usb3" property could be set it allowed to
start the VM in only if an additional USB devices was added to the VM
with USB2, or the VM uses "q35" based machine - as else no "ehci" was
available, and thus the "ignored" USB3 - SPICE could not get attached
anywhere -> QEMU chickened out.
And if a user had a configuration where this could started we have
still a bit luck, live-migration was not possible as the "can't
migrate VM which uses local devices:" check still hit, as in
qemu-server older than 6.0-8 we explicitly checked for "spice" when
seeing what usb device were not local, so a "spice,usb3=X" was always
(luckily) wrongly detected as local device -> migration was blocked.
So we only have one case left: restoring a live-snapshot. Here sadly
there seems no way out, it was possible to do with a "spice,usb3=1"
usb device, and thus all Snapshots taken on such VMs after they had a
clean restart on PVE 6 (to have a machine version >= 4.0) are broken
- but can be easily fixed by removing the "usb3=1" from the
problematic snapshot config.
As restoring a snapshot can be repeated more than once even on
failure without rendering the snapshot or VM permanently unusable,
this should be a reasonable compromise.
I strongly believe that the chance is so small that no one is
affected in practice and the property description mentioned that it
was not supported. If anybody is affected on snapshot restore we can
help them on a case-per-case basis.
