- Architecture of FreeBSD Embedded Testing Environment
-
- Host Machine
-
- Provides connectivity to the internet, and Jails with root that have
- direct access to each host (so user can control NFS and related issues).
- Best way to provide this is via vnet for each jail. VALE or bridge switch
- and provide one of the direct connection, and one for internet.
-
- Host allows device reservation, and allows each jail to turn on/off
- the device (host can drop socket in the jail, or via union mount). Passes through serial console as well (devfs).
