Hi,
I remember we discussed a long time ago to limit the stack usage of all
functions that are executed in a coroutine
context to a very low value to be able to safely limit the coroutine stack size
as well.
I checked through all functions in block/, migration/ and nbd/ and there are
only
this patch makes the bulk phase of a block migration to take
place before we start transferring ram. As the bulk block migration
can take a long time its pointless to transfer ram during that phase.

Hi,
I noticed that Qemu quits at several points with an exit() if the supplied
parameters in the commandline are incorrect.
This at some stages happens after there have already been connections to
storage backends established.
These connections are not cleanly shut down in this case. For posix

Hi,
I just noticed that CPU throttling and Block Migration don't work together very

During block migration the throttling heuristic detects that we obviously make
no progress
