RH-MergeRequest: 62: Fix hot unplug of devices created with -device JSON syntax
RH-Commit: [1/1] 980e505ba215b5f9324c107481c5bb257ae03f42 (kmwolf/centos-qemu-kvm)
RH-Bugzilla: 2036669
RH-Acked-by: Daniel P. Berrangé <berrange@redhat.com>
RH-Acked-by: Laurent Vivier <lvivier@redhat.com>
RH-Acked-by: Jano Tomko <None>
The -device JSON syntax impl leaks a reference on the created
DeviceState instance. As a result when you hot-unplug the
device, the device_finalize method won't be called and thus
it will fail to emit the required DEVICE_DELETED event.
A 'json-cli' feature was previously added against the
'device_add' QMP command QAPI schema to indicated to mgmt
apps that -device supported JSON syntax. Given the hotplug
bug that feature flag is not usable for its purpose, so
we add a new 'json-cli-hotplug' feature to indicate the
-device supports JSON without breaking hotplug.

Add the new 8.6.0 machine type; note that while the -AV
notation has gone in the product naming, just keep the smbios
definitions the same for consistency.

Add a rhel-9.0.0 q35 machine type; it's currently identical to 8.6.0;
but having a separate machine type will make life easier in the future
when the 8.x types go away.
Note: The smbios stream product name has now changed to 'RHEL'
