not today no. nova does not actuly implemnte auto converge libvirt does we just turn it on if you enable it in the config. i do not think there is a disk io equivelent althoug post-copy migration will help as it will tansiation to the dest host faster and redirect the writes sooner as a result.

Is there any option for disk I/O auto-convergence like conf.libvirt.live_migration_permit_auto_converg for memory-intensive instances?
The use case is for an I/O intensive VM, so the disk cannot be migrated. Instead, it is necessary to change the max IO with
`$ virsh blkdeviotune`
then, migrate the instance and replace the current value with the old using the same command.
