Subject: [Virtio-fs] [PATCH v2 00/51] migration patches for VFIO
Date: Mon, 5 Dec 2022 10:51:37 +0100 [thread overview]
Message-ID: <20221205095228.1314-1-quintela@redhat.com> (raw)
Hi
On this v2:
- Remove the stop of the guest to calculate the size
- Rebase on latest upstream.
Please review.
[v1/RFC]
VFIO migration has several requirements:
- the size of the state is only known when the guest is stopped
- they need to send possible lots of data.
this series only address the 1st set of problems.
What they do:
- res_compatible parameter was not used anywhere, just add that information to res_postcopy.
- Remove QEMUFILE parameter from save_live_pending
- Split save_live_pending into
* save_pending_estimate(): the pending state size without trying too hard
* save_pending_exact(): the real pending state size, it is called with the guest stopped.
- Now save_pending_* don't need the threshold parameter
- HACK a way to stop the guest before moving there.
ToDo:
- autoconverge test is broken, no real clue why, but it is possible that the test is wrong.
- Make an artifact to be able to send massive amount of data in the save state stage (probably more multifd channels).
- Be able to not having to start the guest between cheking the state pending size and migration_completion().
Please review.
Thanks, Juan.
