Ticket #12117, comment 1
initial v1 1 This information may weakenthe multi-processor synchronization conjecture. The effect is definitely worse with multi-cpu's in the guest, but transfers still hang with single-cpu guest configuration:1 More information relevant to the multi-processor synchronization conjecture.

IIRC, the VM gets a dedicated CPU in a multiprocessor host environment, thus they will always be executing on different CPUs. Having 4 instead of 1 guest CPUs apparently increases the stress level. 29
