Block live migration
This patch introduces block migration called during live migration. Blockare being copied to the destination in an async way. First the code willtransfer the whole disk and then transfer all dirty blocks accumulted duringthe migration....
unify popen/fopen qemu wrappers
While reading Chris's code for fd migration I noticed the duplicationbetween QEMUFilePopen and QEMUFileStdio. This fixes it, and makesqemu_fopen more similar qemu_popen.

Fix detached migration with exec.
When trying to do detached migration with exec, I found thatthe monitor wouldn't always return in a timely manner. Itracked this down to exec_start_outgoing_migration. Itappeared we were setting the fd to NONBLOCK'ing, but in...
fix migration to obey -S
Since migration returns right away, starting the VM rightafter calling qemu_start_incoming_migration is wrong evenif -S is not passed. We have to do this after migrationhas completed.

honor -S on incoming migration
-S is not honored by qemu on incoming migration. If a domain is migratedwhile paused, thus, it will start running on the remote machine; thisis wrong.
Given the trivial patch to fix this, it looks more like a thinkothan anything else, probably dating back to the qemu-kvm merge....
Allow monitor interaction when using migrate -exec
All, I've recently been playing around with migration via exec. Unfortunately,when starting the incoming qemu process with "-incoming exec:cmd", it suffersthe same problem that -incoming tcp used to suffer; namely, that you can't...
monitor: Decouple terminals (Jan Kiszka)
Currently all registered (and activate) monitor terminals work inbroadcast mode: Everyone sees what someone else types on some otherterminal and what the monitor reports back. This model is broken whenyou have a management monitor terminal that is automatically operated...
monitor: Rework API (Jan Kiszka)
Refactor the monitor API and prepare it for decoupled terminals:term_print functions are renamed to monitor_* and all monitor servicesgain a new parameter (mon) that will once refer to the monitor instancethe output is supposed to appear on. However, the argument remains...

Fix brown-paper-bag bugs from live-migration patch (Charles Duffy)
In TCP migration, prevent an endless loop trying to retrieve error status. Inexec migration, set the close pointer in the FdMigrationState structure.
Color me embarrassed.

Reintroduce migrate-to-exec: support (Charles Duffy)
KVM's live migration support included support for exec: URLs, allowing systemstate to be written or received via an arbitrary popen()ed subprocess. Thisprovides a convenient way to pipe state through a compression algorithm or an...
