[Bug 1955411] [NEW] Ping loss when live migration
Public bug reported:
Description
===========
Hi, we are seeing 4 to 12 ping packet loss on our victoria cluster when
live migrating instances.
Is this behaviour normal? We had several tests with different flavors
and different cpu/memory loads on instance but still loosing same number
of pings. (Memory-CPU load does not affect)
Steps to reproduce
==================
Live migrate an instance from host A to host B.
Ping loss from instance to outside:

Expected result
===============
No ping loss should be occur. (Or may be 1 or 2 pings?)
Actual result
=============
Lost too many pings.
Migrate API request logs attached.
