MNX virtual machines (VMs) are hardware virtual machines (HVMs) wrapped in highly secure zones, supporting a variety of images including Linux, FreeBSD, Windows, and Docker Engine. They offer a solution for a wide variety of applications that have certain operating system dependencies or applications that can't be run in a containerized environment. Triton offers support for these applications via hardware virtualization but there are some differences between infrastructure containers and virtual machines to be aware of.
