They should at least announce that issue globally.
I got new cpu specifficly for nested virt workloads.
Turns out - that "patch" makes it so windows can't use nested virt.
Its complaining about missing features.

Bigger issue - windows does not have patch applied afaik.
This means that win host with hyperv enabled can crash anytime.

Back to linux - disabling vls does have performance penalty around 10-20% as
far as i tested.
