SmartOS does not require installation, as it is a type 1 hypervisor running in read-only mode from random access memory. All of the stable storage in a system is used for /zones, which store the actual containers.

Set up a pxegrub, TFTP and DHCP server, and boot it straight from the network on a node. Console on ttya or ttyb recommended but not required.

SmartOS can also be booted from a USB stick. All of the above is available on http://smartos.org/
