Azure has had nested virt available for a while too. I used to run HyperV in cloud

Azure has recently announced "direct virtualization", which is a sort of logical nesting, in which users can sub-partition their L1 VMs into virtual L2 VMs that are technically siblings.

Cool, so that’s the new and preferred model for nested or sibling virt?

eventually yes, this is supposed to remove the perf tax of nested virtualization (less world/context switches on vm_exits) and unlocks some new use cases (pass through hardware from your VM to the sibling-guest).

Interesting ! I stopped working in Azure back in August. But I know of teams still using the nested virt HyperV setup I created to allow multicast to between VMs in Cloud.
