      migration (outgoing): add error propagation for all protocols · f37afb5a
      由 Paolo Bonzini 提交于 
      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.

Before:

    (qemu) migrate fd:ffff
    migrate: An undefined error has occurred
    (qemu) info migrate
    (qemu)

After:

    (qemu) migrate fd:ffff
    migrate: File descriptor named 'ffff' has not been found
    (qemu) info migrate
    capabilities: xbzrle: off
    Migration status: failed
    total time: 0 milliseconds

      Block live migration · c163b5ca
      由 lirans@il.ibm.com 提交于 
      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.

      fix migration to obey -S · d399f677
      由 Paolo Bonzini 提交于 
      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
      由 Paolo Bonzini 提交于 
      -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.

      Allow monitor interaction when using migrate -exec · 8a43b1ea
      由 Chris Lalancette 提交于 
      All,
     I've recently been playing around with migration via exec.  Unfortunately,
when starting the incoming qemu process with "-incoming exec:cmd", it suffers
the same problem that -incoming tcp used to suffer; namely, that you can't
interact with the monitor until after the migration has happened.  This causes
problems for libvirt usage of -incoming exec, since libvirt expects to be able
to access the monitor ahead of time.  This fairly simple patch allows you to
access the monitor both before and after the migration has completed using exec.

(note: developed/tested with qemu-kvm, but applies perfectly fine to qemu)
