I don't know exactly how it is used in XOA but it looks like it has been merged last week in XO(see https://github.com/vatesfr/xen-orchestra/pull/8144) and I know that Cecile tested it on her setup. So maybe there is a mismatch with the version of XOA you are using?
Otherwise from the point of view of xcp-ng you just need to copy the python file in /etc/xapi.d/plugins/ and there is nothing else to do.

@stevewest15 Thx for SMlog. I don't see anything suspicious

In the log of the source host I see Oct 14 20:09:06 XCP25 xapi: [error||3 ||storage_migrate] Tapdisk mirroring has failed
Can you also provide /var/log/SMlog that corresponds to the migration time. As it was yesterday maybe you should look in /var/log/SMlog.1
Thx
