This sounds similar to what Kemari was looking to achieve: http://wiki.qemu.org/Features/FaultTolerance But unfortunately, I believe Kemari development has halted. -----Original Message----- From: kvm-owner@xxxxxxxxxxxxxxx [mailto:kvm-owner@xxxxxxxxxxxxxxx] On Behalf Of Valentin Zagura Sent: Saturday, May 11, 2013 8:30 AM To: kvm@xxxxxxxxxxxxxxx Subject: Hot Spare Virtual Machines I was thinking the other day if one can modify the live migration feature of KVM to allow keeping a remote hot copy of a virtual machine snapshot every say 10 seconds. And in the same time to use LVM or something similar so the modifications to the storage would be committed at every succesfull snapshot stored remotely. This way, whenever the hardware that runs the VM has a hardware problem, the spare could continue from the snapshot. I imagine that there can also be a software on the router between the VM and the Internet that could log all the traffic from the outside done since the last snapshot and could eventually replay it to the new hot spare VM that just started whenever is needed. Would this be feasible? :) Valentin Zagura http://zagura.com -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
