[Xen-devel] [PATCH 0/2] Revert changes to libxl_set_memory_target, unblock 4.6

[Wei Liu <wei.liu2@xxxxxxxxxx>]

A new memory model that allows QEMU to bump memory behind libxl's back was
merged a few months ago. We didn't fully understand the repercussions back
then. Now it breaks migration and becomes blocker of 4.6 release.

It's better to restore to original behaviour at this stage of the release
cycle, that would put us in a position no worse than before, so the release is
unblocked.

The said function is still racy after reverting these two patches. Making
domain memory state consistent requires a bit more work. Separate patch(es)
will be sent out to deal with that problem.

Wei.
