Since we switched from direct host migration scheme to the one, where we connect to the destination and then just pass a FD to a qemu, we have uncovered a qemu bug. Qemu expects migration FD to block. However, we are passing a nonblocking one which results in cryptic error messages like:
qemu: warning: error while loading state section id 2 load of migration failed
The bug is already known to Qemu folks, but we should workaround already released Qemus. Patch has been originally proposed by Stefan Hajnoczi <stefanha@gmail.com> --- src/qemu/qemu_migration.c | 7 +++++++ 1 file changed, 7 insertions(+)
Thanks for figuring it all out! I definitely hit this one, while trying to help someone on IRC.
ACK, and definitely 1.0.4 material.
Thanks, pushed to master. I wonder if it should be pushed to stable branches as well. Doug, Cole - what do you think?

Agreed. That's definitely a regression since we've switched and the patch is very straight forward. -- Doug Goldstein
