online migration with replication possible in the near future?

[udo]

Hi,
I'm playing with replication and must stop an VM for an migration, because online migration isn't supported.

In the manual it's described:

Virtual guest with active replication cannot currently use online migration

Now my questions:
- Is this an feature for the next time?
- would an Online-Migration with an stopped replication work? And enabled again, if the VM migrate back?

Background is the reboot of one node to activate the security-paches.

Hi udo,

Yes it will come in the future.
But I cant tell you when the problem is there are some missing functionality in qemu.
It is not much what is missing.

- would an Online-Migration with an stopped replication work? And enabled again, if the VM migrate back?

No you have to destroy the image on the Riverside.
It is not the replication which make the problems it is the existing image.
At the moment Qemu can't send diff with qemu-nbd.

By the way you can migrate online if the target is not the replication target.
