This sort of feels like seeing someone riding a bike and saying: why don’t they just get a car? The simple fact is that containers and VMs are quite different.
I’m responding to what I believe is the intent of the comment, but I will also point out that on a literal level it doesn’t make sense. Whether something uses VMX and friends or not is a red herring, as gVisor also “rolls it own” VMM [1] and certainly makes use of VMX and friends.
