Hardware is now setup, but might still be missing additional resources to spawn new vms.

So your code will create the vms it needs via restapi/sdk?

nested vms might be ready soon, after a major bug was fixed on kernel, we currently test its functionality again and we'll update once(if) it's verified and working.

In a case that nested VMs wont work because of the kernel bug, can you use fake hosts instead ?

(at least for testing at first) hopefully we'll know if it works by the end of the week
