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.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
