Try to reconnect to the running domains after libvirtd restart. To
achieve that, do:
* Save domain state
- Modify virBhyveProcessStart() to save domain state to the state
dir
- Modify virBhyveProcessStop() to cleanup the pidfile and the state
* Detect if the state information loaded from the driver's state
dir matches the actual state. Consider domain active if:
- PID it points to exist
- Process title of this PID matches the expected one with the
domain name
Otherwise, mark the domain as shut off.
Note: earlier development bhyve versions before FreeBSD 10.0-RELEASE
didn't set proctitle we expect, so the current code will not detect
it. I don't plan adding support for this unless somebody requests
this.
