      migration (outgoing): add error propagation for all protocols · f37afb5a
      Paolo Bonzini authored
      Error propagation is already there for socket backends.  Add it to other
      protocols, simplifying code that tests for errors that will never happen.
      With all protocols understanding Error, the code can be simplified
      further by removing the return value.
      Unfortunately, the quality of error messages varies depending
      on where the error is detected, because no Error is passed to the
      NonBlockingConnectHandler.  Thus, the exact error message still cannot
      be sent to the user if the OS reports it asynchronously via SO_ERROR.
      If NonBlockingConnectHandler received an Error**, we could for
      example report the error class and/or message via a new field of the
      query-migration command even if it is reported asynchronously.

          migrate: File descriptor named 'ffff' has not been found
          (qemu) info migrate

      Block live migration · c163b5ca
      lirans@il.ibm.com authored
      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
      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.

      fix migration to obey -S · d399f677
      Paolo Bonzini authored
      Since migration returns right away, starting the VM right
      after calling qemu_start_incoming_migration is wrong even
      if -S is not passed.  We have to do this after migration
      has completed.

      honor -S on incoming migration · 89befdd1
      Paolo Bonzini authored
      -S is not honored by qemu on incoming migration.  If a domain is migrated
      while paused, thus, it will start running on the remote machine; this
      is wrong.
      Given the trivial patch to fix this, it looks more like a thinko
      than anything else, probably dating back to the qemu-kvm merge.
      The interesting part is that the -S mechanism was in fact *used* when
      migrating (setting autostart = 0) and the incoming migration code was
      starting the VM at the end of the migration.
      Since I was removing the vm_start from there, I also corrected a related
      imprecision.  The code was doing a vm_stop "just in case", but we can
      be sure that the VM is not running---the vm_start call in vl.c has not
      been reached yet.  So the vm_stop is removed together with the vm_start.
