Seyeong Kim (xtrusia): You need to test with the following setup: * The source needs to run qemu 1.5. (which should be unpatched) * The destination needs to run a *PATCHED* versions of qemu 2.0 and libvirt 1.2. Furthermore, libvirt *NEEDS* to have allow_incoming_qemukvm set to true.
Failure to set allow_incoming_qemukvm to true will result in this error: Length mismatch: 0000:00:03.0/virtio-net-pci.rom: 20000 in != 40000 qemu: warning: error while loading state for instance 0x0 of device 'ram' Your logs show that you failed to follow the test steps as the destination isn't using the "pc-i440fx-1.5-saucy" machine type as expected. Make sure libvirt is properly configured and restarted with "allow_incoming_qemukvm". The proposed patches (both libvirt and qemu) have been running in production environment without any issue since the bug report. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu in Ubuntu. https://bugs.launchpad.net/bugs/1425619 Title: Migration fails between QEMU 1.5 and QEMU 2.0 To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1425619/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
