[Qemu-devel] [PATCH 0/2] Add some tracepoints for live migration

[Kazuya Saito]

This series adds tracepoints about state transition of VM to get
information of live migration.
We suggest that QEMU trace data will be able to be captured by users
all the time for investigation on production server not for
development. However, tracepoints in current QEMU are not enough to
achieve the purpose. So, we're going to add tracepoints for it.
As a first step, we add tracepoints related in live migration which
got us in trouble before.
