Serialize VMCS state for transfer

pub fn final_dirty_pages(&self) -> Result<Vec<u64>, VmError>

Get remaining dirty pages for stop-and-copy final transfer

pub fn complete(&mut self) -> Result<(), VmError>

Complete the migration

pub fn fail(&mut self)

Mark migration as failed

pub fn state(&self) -> MigrationState

pub fn progress(&self) -> &MigrationProgress
