[Qemu-devel] HEAD is failing virt-test on migration tests

[Juan Quintela]

Hi

while testing my changes I noticed that virt-test was failing.  I
check-out master, and failures are there.

This is one extract of the log after the 1st failure.  Notice that it
fails randomly, not every time.

I have to go to bed right now, so if anybody beats me with a fix, I
would be happy when I wakeup.

Thanks, Juan.
