Hello, This series fixes a few issues pointed out by Avi and Juan. Avi pointed out we should do full scatter/gather processing of guest data even if current (well-behaved) guests don't send multiple iovs per element. Juan pointed out a few migration-related bugs. In handling the migration fixes, I noticed hot-plug/unplug isn't handled perfectly for the migration case: ports are

...case to add one for! For many other (userspace) use-cases, see the qemu-guest-agent in the qemu sources. The API is documented in the wiki: http://www.linux-kvm.org/page/Virtio-serial_API and the feature pages have some information that may help as well: https://fedoraproject.org/wiki/Features/VirtioSerial There are some links in here too: http://log.amitshah.net/2010/09/communication-between-guests-and-hosts/ Hope this helps.
