You said before that it was happening on a 32GB image - is it *only* happening on a 32GB or bigger VM, or is it just more likely?
Not image, memory. I've only seen this with vms having more than 16GB or 32GB memory. But maybe this also indicates that just the migration takes longer.
Don't know. Sadly i cannot reproduce this with test VMs only with production ones.I think you also said you were using 1.7; have you tried an older version - i.e. is this a regression in 1.7 or don't we know?
