Changes in v3:
* improve code readibility for Windows machine version fallback change
Changes in v2:
* change deprecation logic into QEMU itself rather than just weakening
the warning there (so no need to change the deprecation logic in
qemu-server anymore)
* get rid of outdated information from "Update to a Newer Machine
Version" section in docs
In QEMU commit a35f8577a0 ("include/hw: add macros for deprecation &
removal of versioned machines"), a new machine version deprecation and
removal policy was introduced. After only 3 years a machine version
will be deprecated while being removed after 6 years.
The deprecation is a bit early considering major PVE releases are
approximately every 2 years. This means that a deprecation warning can
already happen for a machine version that was introduced during the
previous major release. This would scare users for no good reason, so
avoid deprecating machine versions in PVE too early and define a
baseline of machine versions that will be supported throughout a
single major PVE release.
The new policy takes effect only in QEMU 10.1, see QEMU commit
c9fd2d9a48 ("include/hw: temporarily disable deletion of versioned
machine types"). Machine versions <=2.3 were already deprecated for a
while, with PVE also warning about it since commit dec371d9 ("vm
start: add warning about deprecated machine version") in qemu-server
8.0.8. These have been dropped in QEMU 9.1, so the baseline for PVE 8
is 2.4.
This series is intended to allow broader QEMU 9.1 rollout. Still
required in addition to this series before PVE 9:
* wiki article about what to look out for when changing machine
version
* checks in pve8to9 script giving errors/warnings when machine version
is too old
