OpenIndiana oi_151a was released on 14th September 2011, exactly one year after our first release, oi_147. Our latest build brings a wide variety of enhancements, including being our first build based on Illumos. Notable changes to the kernel and core userland since OpenIndiana's oi_148 release includes KVM, the open source kernel-based Virtual Machine, as a basic virtualization solution along with the QEMU package. This KVM port includes virtualization extensions for Intel VT. Using KVM, a user or system administrator can run multiple virtual machines running unmodified x86_64-based operating system images for Linux, BSD, or Windows images. Each virtual machine has private virtualized hardware.
