Comment 29 for bug 1413540

Hm, following your instructions I rather run into a situation where the l2 guest gets paused. Likely because l1 runs out of disk space. The default of uvtool is 7G which I would say the l2 stress run fills as it grows the l2 qcow image on l1 which has to stuff all the initial cloud-image and the snapshot of that for l2 into its 7G.
