Hi,
This patch series is a revised version of Kemari for KVM, which
applied comments for the previous post. The current code is based on
qemu.git 05bf441eb69a813d3893174d54faa6afa8c0d39b.
The changes from v0.2.2 -> v0.2.3 are:
- queue async net requests without copying (MST)
-- if not async, con
Currently buf size is fixed at 32KB. It would be useful if it could
be flexible.

This code implements VM transaction protocol. Like buffered_file, it
sits between savevm and migration layer. With this architecture, VM
transaction protocol is implemented mostly independent from other
existing code.

For regular migration inuse == 0 always as requests are flushed before
save. However, event-tap log when enabled introduces an extra queue
for requests which is not being flushed, thus the last inuse requests
are left in the event-tap queue. Move the last_avail_idx value sent
to the remote back to
event-tap controls when to start FT transaction, and provides proxy
functions to called from net/block devices. While FT transaction, it
queues up net/block requests, and flush them when the transaction gets
completed.

When ft_mode is set in the header, tcp_accept_incoming_migration()
sets ft_trans_incoming() as a callback, and call
qemu_file_get_notify() to receive FT transaction iteratively. We also
need a hack no to close fd before moving to ft_transaction mode, so
that we can reuse the fd for it.

Introduce skip_header parameter to qemu_loadvm_state() so that it can
