SmartOS In a Nutshell¶
SmartOS is a specialized Type 1 Hypervisor platformbased on illumos. It supports two types of virtualization:
- OS Virtual Machines (Zones): A light-weight virtualization solution offering a complete and secure userland environment on a single global kernel, offering true bare metal performance and all the features illumos has, namely dynamic introspection via DTrace
- Hardware Virtual Machines (KVM, Bhyve): A full virtualization solution for running a variety of guest OS's including Linux, Windows, *BSD, Plan9 and more
SmartOS is a 'live OS', it is always booted via PXE, ISO, or USBKey and runs entirely from memory, allowing the local disks to beused entirely for hosting virtual machines without wasting disksfor the root OS. This architecture has a variety of advantagesincluding increased security, no need for patching, fast upgradesand recovery.
Virtualization in SmartOS builds on top of the foundational illumostechnologies inherited from OpenSolaris, namely:
- ZFS for storage virtualization
- Crossbow (
dladm) for network virtualization - Zones for virtualization and containment
- DTrace for introspection
- SMF for service management
- RBAC/BSM for auditing and role based security
- And more
SmartOS is typically 'installed' by downloading and copying the OSimage onto a USB key and then booting that key. On the first boota configuration utility will configure your base networking, allowyou to set the root password, and allow you to select which disksto use to create the ZFS Zpool which will provide persistent storage.

When you log into SmartOS you will enter the 'global zone'. Fromhere you can download VM Images using the imgadm tool, which arepre-configured OS and KVM virtual machines. You can then use thevmadm tool to create and manage both OS and hardware virtualmachines.
An important aspect of SmartOS is that both OS (Zones) and hardwarevirtual machines are both built on Zones technology. In the caseof OS virtualization, the guest virtual machine is provided with acomplete userland environment on which to run applications directly.In the case of HVM virtualization, the qemu or bhyve processwill run within a stripped down Zone. This offers a variety ofadvantages for administration, including a common method for managingresource controls, network interfaces, and administration. It alsoprovides HVM guests with an additional layer of security and isolationnot offered by other virtualization platforms.
Finally, instances are described in JSON. Both administrativetools, imgadm and vmadm, accept and return all data in JSONformat. This provides a simple, consistent, and programmaticinterface for creating and managing VM's.
