Description Cole Robinson 2013-05-25 22:46:56 UTC
F19 source and destination host (I'm using a VM for the destination but I don't think that matters).

Both hosts have qemu-1.4.2-1, which has the migration cleanup series from qemu-1.5 backported, including this commit which sounds like it could have been related:

    Revert "migration: don't account sleep time for calculating bandwidth"

I'm migrating with: sudo virsh migrate --p2p --tunnelled --verbose --live  --copy-storage-all f19-migrate qemu+ssh://root@192.168.123.99/system

After progress meter reaches 99% the migration fails. This is in the destination qemu log:

Receiving block device images
qemu: warning: error while loading state section id 2
load of migration failed

Full qemu command line and logs coming up.

FWIW I was more or less following the steps here:

Comment 4 Paolo Bonzini 2013-06-20 11:58:30 UTC
Can you try without --p2p and --tunnelled?

Comment 5 Cole Robinson 2013-06-20 14:15:44 UTC
Yeah I think this was some side effect of libvirt silently falling back to the old storage migration method, which current F19 libvirt doesn't do anymore. Since we don't really care about that method, closing this as WONTFIX. I'll reopen if I can reproduce with the nbd migration method.
