cold migration/resize with config drive from pc to q35 fails boot

[Michal Nasiadka]

OpenStack release: Yoga

When cold migrating/resizing a pc (i440) instance with config drive to a compute with libvirt.hw_machine_type = x86_64=q35 - the instance gets migrated from pc to q35.

In my case - I'm using config drive - which ends up as IDE device, which is not translated to SATA device and nova-compute shows following error:
2024-02-18 06:57:44.807 7 ERROR oslo_messaging.rpc.server raise libvirtError('virDomainDefineXML() failed') 2024-02-18 06:57:44.807 7 ERROR oslo_messaging.rpc.server libvirt.libvirtError: unsupported configuration: IDE controllers are unsupported for this QEMU binary or machine type
