Further to my last comment, some real-world network testing of the applications running on the guests has shown that although the guests resume to use all CPUs the overall performance is sub-standard compared to a clean startup of the host (no suspend). I don't have any firm numbers to share, just hands-on experience with video streams becoming very unstable after a resume, even with a VM guest reboot. A fresh reboot of the host fixed this substandard behaviour.
