dprintf is already claimed by POSIX[1], and on at least one system is implemented as a macro [1] http://www.opengroup.org/onlinepubs/9699919799/functions/dprintf.html Signed-off-by:

In order to allow proper progress reporting to the monitor that initiated the migration, forward the monitor reference through the migration layer down to SaveLiveStateHandler. Signed-off-by:

So far progress reporting only works for the first block device. Fix this by keeping an overall sum of sectors to be migratated, calculating the sum of all processed sectors, and finally basing the progress display on those values. Signed-off-by:

Introduce qemu_savevm_state_cancel and inject a stage -1 to cancel a live migration. This gives the involved subsystems a chance to clean up dynamically allocated resources. Namely, the block migration layer can now free its device descriptors and pending blocks. Signed-off-by:

We already save total_sectors in BlkMigDevState, let's use this value during the migration and avoid to recalculate it needlessly. Signed-off-by:

Instead of duplicating the definition of constants or introducing trivial retrieval functions move the SECTOR constants into the public block API. This also obsoletes sector_per_block in BlkMigState. Signed-off-by:

This patch introduces block migration called during live migration. Block are being copied to the destination in an async way. First the code will transfer the whole disk and then transfer all dirty blocks accumulted during the migration. Still need to improve transition from the iterative phase of migration to the end phase. For now transition will take place when all blocks transfered once, all the dirty blocks will be transfered during the end phase (guest is suspended). Changes from v4: - Global variabels moved to a global state structure allocated dynamically. - Minor coding style issues. - Poll block.c for tracking of dirty blocks instead of manage it here.
