Comments on: Leaner virtualization coming to Windows, Linux

Microsoft works to make one copy of Windows look like many, while the Linux equivalent gains ground.

Chroot?

Is this similar to a chroot? or User Mode Linux?

Chroot is for security not virtualization

With chroot you are running a program on a different root filesystem that prevents any problems in that process from causing problems in the main filesystem of the operating system. This is common with web servers, databases, etc., where the process you are trying to protect may be subject to an attack that allows access to other data on the system. But you only have one instance of the OS and you only have the services available that exist within that OS.

With virtualization you are running a new instance of an operating system whether it is the same OS or a different one. The instances are separated from each other and each OS instance acts as if it were a standalone machine. Thus you may run Plan 9, FreeBSD, Solaris, Windows, Minix or any individual OS or combination of OSes if you have enough RAM, disk space and processor horsepower. You may chroot processes within each virtual machine if you want to add that level of security "sandboxing" within the VM.
