Hibernate

Hibernate captures paused machine state for a running machine and stops the active VM. Use reusable snapshots when the source should keep running and the captured state should start many future machines.

What state changes

The running machine stops accepting new work.
A paused-machine snapshot ID is created and returned for Machine.resume(...).
Shared volume attachments are preserved as remount intent, not as VM memory.

Usage

from nullspace import Machine

machine = Machine.create(template="base", timeout=600)
machine.files.write("/workspace/state.txt", "before hibernate\n")
snapshot = machine.hibernate()
print(snapshot.id)

nullspace machine pause mch_123
