[Qemu-devel] [PATCH v3 0/4] colo: Add support for continious replication

[Lukas Straub <lukasstraub2@web.de>]

Hello Everyone,
These Patches add support for continious replication to colo. This means
that after the Primary fails and the Secondary did a failover, the Secondary
can then become Primary and resume replication to a new Secondary.

On a side note, I wrote a Pacemaker Resource Agent for colo which I will
post when its ready.
I have to say it's quite fun to randomly kill a Node, wait for resync
and repeat and see how the VM stays alive all the time. :)

Regards,
Lukas Straub

 - add test for replication changes
