Guys, What about Virtual Machine Asynchronous replication under OpenStack?
Something like: http://wiki.xen.org/wiki/Remus Or: http://wiki.qemu.org/Features/FaultTolerance This way, your can take the power cable off the physical compute node, that all of your instances will be up and running on second node. No downtime, not even TCP connection will be lost, like SSH or Windows RDP sessions! Can we make OpenStack aware of Remus? And deal with this? I mean, I think that OpenStack must create two instances, and put it in sync, when you launch one instance that must be under H.A.. Looks like "quantum entanglement" for Virtual Machines... :-P I know that there are something similar to Remux (Xen) for QEmu, called Kemari but, I don't know if it is under development... http://www.linux-kvm.org/images/0/0d/0.5.kemari-kvm-forum-2010.pdf Remus Xen: https://www.youtube.com/watch?v=2jV4lOgFJMY Kemari QEMu: https://www.youtube.com/watch?v=YrVNZG77PhY Cheers!
