Hi, I can confirm that this report makes sense. I was the person reporting it upstream and doing some debugging/bisecting to find the cause.
https://lists.xenproject.org/archives/html/xen- devel/2018-12/msg02403.html The bug causes the uptime of the two dom0s that live migration is done from/to to have an effect on the uptime counter (as seen in dmesg output) of the domU. This causes TCP timestamps to bork all over the place and cause network connections to stall. I'd advise the reporter to test this kernel with the patch applied and use it in a reproduction scenario, where live migrate hits the bug all the time, and where it doesn't hit it anymore with the patch.
