Automatically Start VirtualBox Web Service on Oracle Solaris 11

Per Oracle VM VirtualBox Administrator's Guide for Release 6.0: 2.19. Starting the Oracle VM VirtualBox Web Service Automatically:

The Oracle VM VirtualBox web service, vboxwebsrv, is used for controlling Oracle VM VirtualBox remotely. It is documented in detail in the Oracle VM VirtualBox Software Development Kit (SDK). See Chapter 4, Oracle VM VirtualBox Programming Interfaces.

You can learn more about how to interact with the VirtualBox Web Service through the SDK Programming Guide (API Reference).

The official documentation (VirtualBox Documentation: Chapter 9. Advanced Topics: 9.18.2. Oracle Solaris: Starting the Web Service With SMF) is somewhat convoluted. Here I will try to straighten it out, for my purposes - your mileage may vary.

First, configure the parameters. They are provided in the documentation as a table of Linux environment variables to be loaded in /etc/defaults/virtualbox; on Solaris we must provide these to svccfg on the command line both lower-cased and prefixed with config/.

Parameter Description Default
USER The user which the web service runs as
HOST The host to bind the web service to localhost
PORT The port to bind the web service to 18083
SSL_KEYFILE Server key and certificate file, in PEM format
SSL_PASSWORDFILE File name for password to server key
SSL_CACERT CA certificate file, in PEM format
SSL_CAPATH CA certificate path
SSL_DHFILE DH file name or DH key length in bits
SSL_RANDFILE File containing seed for random number generator
TIMEOUT Session timeout in seconds, 0 disables timeouts 300
CHECK_INTERVAL Frequency of timeout checks in seconds 5
THREADS Maximum number of worker threads to run in parallel 100
KEEPALIVE Maximum number of requests before a socket will be closed 100
ROTATE Number of log files, 0 disables log rotation 10
LOGSIZE Maximum log file size to trigger rotation, in bytes 1MB
LOGINTERVAL Maximum time interval to trigger log rotation, in seconds 1 day

For example:
svccfg -s svc:/application/virtualbox/webservice:default setprop config/host=localhost svccfg -s svc:/application/virtualbox/webservice:default setprop config/port=18083 svccfg -s svc:/application/virtualbox/webservice:default setprop config/user=user

The documentation provides the example for config/user as root. I could not more strongly advise against running any sort of network-exposed daemon as root and instead encourage you to configure a local user account with sufficient permissions to both administrate your virtual machines and run the web service.

After making any changes via svcconfig while the service is running you must run the following to make the changes live:
svcadm refresh svc:/application/virtualbox/webservice:default

To view the current configuration run:
# svcprop -p config svc:/application/virtualbox/webservice:default config/host astring localhost config/keyfile astring "" config/port integer 18083 config/user astring user

When your configuration is satisfactorily complete run:
svcadm enable svc:/application/virtualbox/webservice:default

To shut down a currently running instance of the service supply disable instead:
svcadm disable svc:/application/virtualbox/webservice:default
