Ok, thanks.

We want to carve out some resources (e.g. vcpu, mem, pci_dev) from the user's 
VM and then use these resources to start a sandbox for the user. The usage 
quite likes the software enclave which Nitro already supported, but we have 
much wider usage, for example, running unikernel + app (e.g. OSV + Redis) in 
the sandbox, it would provide much better performance than the traditional os.
