That page is a bit out of date; I'd say that nesting is finally getting usable. Indeed if you follow the bugzilla links on there, the RH bz 1076294 got duped in December to bz 1738741 which was marked verified a few weeks back.
While I'd still suggest some caution with nesting, if you get all your hypervisors in a line it does work now.
Testing of it varies a bit; e.g. there's quite a bit of kvm-on-kvm nest testing; there's probably less testing on the various KVM under other things nesting.

As an addendum to what Dave wrote, yes, the above page will be retired in favor of this in-progress draft (once I address all the feedback, then it'll be ready for merge in the upstream kernel documentation) about nested virt: https://marc.info/?l=kvm&m=158108941605311&w=2 https://marc.info/?t=158108958800002&r=1&w=2 [...] -- /kashyap
