While a very interesting read, I'm curious how much is applicable anymore since the paper is relatively dated. I ask from ignorance not to dismiss the paper.
The reason I ask is because my current line of work heavily involves supporting and troubleshooting VMware and HyperV infrastructures and I frequently do receive cases where we have to consider why the VMs on VMware struggle or have issues with quiescence; I thought this would be a good article to learn a bit about the underpinnings, but for most of the problems they describe near the bottom of the article, the linked VMware KB articles are no longer available - have many of these issues been improved upon and are no longer as relevant?
