| Doc Text: |
Cause:
live migration format for the hda-audio device has changed due to a bugfix
Consequence:
migration from new to old qemu version failed with hda sound active because the old qemu doesn't understand the new migration format.
Fix:
send old migration format when -M $oldversion is used.
Result:
migration works.

Re-test this scenario between RHEL6.2 and RHEL6.1 hosts. And 6.2->6.1 has the same problem migration failed. Reproduced with the command line and steps in bug description between qemu-kvm-0.12.1.2-2.295.el6.x86_64.rpm and qemu-kvm-0.12.1.2-2.160.el6.x86_64. Verified pass between a rhel6.4 host with the following version and a rhel6.1 one with -M rhel6.1.0. rhel6.4 version: qemu-kvm-0.12.1.2-2.337.el6.x86_64 rhel6.1 version: qemu-kvm-0.12.1.2-2.160.el6.x86_64 And also test migration with sound device between two rhel6.4 host, passed.
