Hi, is live migration between qemu-kvm stable-0.15 and stable-1.0 trees possible? When I live migrate a VM from 1.0 to 0.15, the destination side 0.15 qemu-kvm exits with: (qemu) Unknown savevm section or instance 'i8259' 0 That's expected, since commit "i8259:convert to qdev" 747c70af78f7088f182c87e683bdf847beead1e4 introduces the i8259 device in the qdev tree. The other direction (live migrate from 0.15.1 to 1.0.0) seems to work fine. Are any other issues expected in this direction? The vmstate for i8259 has not changed between these trees afaict. If the qdev-ified i8259 is reverted from stable-1.0 tree (to restore live-migration compatibility between the versions), would you expect problems? thanks, - Vasilis -- 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
