My guess is that it’s something that is very much tied to the Linux kernel.
AFAIK, it works on RHEL (and derivatives), and that’s usually a sign that it’s
100% tied to the Linux-kernel.
We have over 20 Vcenters (yeah...) with thousands of VMs and AFAIK, only one
customer has ever requested that feature.
Do you really need it that badly?
