Thanks for pointing at these machines.
But virtio-mmio does not support ioeventfd disabling as in PCI and CCW
devices.
Should this option be added first?
Yes, that was a good idea.

No, it's used for TCG as well (with ARM "-M virt" or x86 "-M microvm").

virtio devices support separate iothreads waiting for
events from file descriptors. These are asynchronous
events that can't be recorded and replayed, therefore
this patch disables ioeventfd for all devices when
record or replay is enabled.
