Today the hypervisor code in vc relies on persist pkg for two things: 1. To get the VM/run store path on the host filesystem, 2. For type definition of the Load/Save functions of the hypervisor interface. For (1), we can simply remove the store interface from the hypervisor config and replace it with just the path, since this is all we really need. When we create a NewHypervisor structure, outside of the hypervisor, we can populate this path. For (2), rather than have the persist pkg define the structure, let's let the hypervisor code (soon to be pkg) define the structure. persist API already needs to call into hypervisor anyway; let's allow us to define the structure. We'll probably want to look at following similar pattern for other parts of vc that we want to make independent of the persist API. In doing this, we started an initial hypervisors pkg, to hold these types (avoid a circular dependency between virtcontainers and persist pkg). Next step will be to remove all other dependencies and move the hypervisor specific code into this pkg, and out of virtcontaienrs. Signed-off-by: Eric Ernst <eric_ernst@apple.com>
