SmartOS is a hypervisor lean enough to run entirely in memory, powerful enough to run as much as you want to throw at it. Provisioning is blindingly fast, thanks to zones and ZFS file system creation.

KVM (Kernel-based Virtual Machine) is described as 'KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm' and is a very popular Virtualization tool in the network & admin category. There are more than 25 alternatives to KVM (Kernel-based Virtual Machine) for a variety of platforms, including Linux, Windows, Mac, Self-Hosted and BSD apps. The best KVM (Kernel-based Virtual Machine) alternative is VirtualBox, which is both free and Open Source. Other great apps like KVM (Kernel-based Virtual Machine) are QEMU, VMware Workstation Pro, VMware Workstation Player and UTM.
