thats weird...

I guess that bug was resolved in qemu-kvm.git. Likely 1a03675db1, but it appears to be part of 0.12 too, so not sure.

What qemu-kvm were you using previously?

i'm using qemu-kvm git from today (aa22e82).

bug #585113 seems to be fixed (this was the irq nobody cared error with virtio_blk or e1000) bug #584516 is still there, but if I set - cpu xxx,-kvmclock it is not triggered. the guest shows current_clocksource = kvm_clock, but migration seems to succeed (at least the ~20
times i tested it since you told me about the flag)

do you have a clue what fixed bug #585113. i would like to backport it to 0.12.4
