@stormi could you provide some more details about the "transient live migration error" with the xenopsd update?
I have been experiencing issues live migrating larger VM's (20-40GB Ram) especially when the memory is in active use (eg MariaDB database). As far as I can tell my issue is related to the VM dynamic memory being reduced to below the actual memory use of the VM at which point a random processes crash - but not sure why this is happening since both the source and target XCP host are under allocated on memory. We upgraded all hosts in the pool before xenopsd was withdrawn and are currently scheduling in downtime for each VM so we can migrate them in an off state which seems to bypass the issue.
