These are very compelling results, no?

8.2.4 (which was released yesterday). Unfortunately, that means that
anyone using CPR in that release will still (eventually) encounter

relevant commits for a possible 8.2.5 ?

Hi Steve,
Thanks for the response.
It looks like literally *just today* 8.2.4 was released. I'll go check
it out.

No surprise

ram and device state being out of sync" as mentioned in the commit.
I am not familiar with the process for maintaining old releases for qemu.
Perhaps someone on this list can comment on 8.2.3.

Hi Steve,
We found that this specific change in particular ("migration: stop vm
for cpr") fixes a bug that we've identified in testing back-to-back live
updates in a lab environment.
More specifically, *without* this change (which is not available in
8.2.2, but *is* available in 9.0.0)
Yu Zhang / Jinpu,
Any possibility (at your lesiure, and within the disclosure rules of
your company, IONOS) if you could share any of your performance
information to educate the group?
NICs have indeed changed, but not everybody has 100ge mellanox cards at
their disposal. Some people don't.

Hi All (and Peter),
My name is Michael Galaxy (formerly Hines). Yes, I changed my last name
(highly irregular for a male) and yes, that's my real last name:

I'm the original author of the RDMA implementation. I've been discussing
with Yu Zhang
the global notifier
list in a new function migration_call_notifiers, and make it externally
visible so future live update code can call it.

Hi Steve,
In the current design you have, we have to specify both the command line
parameter "-migrate-mode-enable cpr-reboot"
*and* issue the monitor command "migrate_set_parameter mode cpr-${mode}".
Is it possible to opt-in to the CPR mode just once over the monitor
instead of having to
questions and we were able to fix those issues.
We will continue our testing throughout the year with more
heavily-loaded workloads, but all in all we would very much be
interested in seeing further reviews on this patch series from others.

Hey Steven,
Have you done any "back-to-back" live update testing before?
I am still doing extensive testing on this myself. I am running into a
bug that I have not yet diagnosed.
It involves the following:
1. Perform a live update (I'm using kexec + PMEM-based live updates). =>
