wow cool. Never heard about unikernels. Does it solve the issue with firecracker of not being able to reclaim memory? Would imagine that can be an issue for a long running app like a constantly busy database
Reclaiming memory is orthogonal to unikernals. It's a concern of the VMM, and Firecracker does support this through the balloon device: https://github.com/firecracker-microvm/firecracker/blob/main...
Now, the unikernel helps us consume less memory, which is a good place to start :-)
