@ronan-a For testing purposes, I did the following: I created a VM on the local SR of a host, installed Linux on it, and configured an ISCSI target. I then added that ISCSI target as an ISCSI SR within xcp-ng pool, and created a small VM on that repository, using XO. While the machine was running, I performed a migration without losing a single ping.I assume this confirms my previous assertion regarding the use of a standard storage system.
