Mesin virtual: Perbedaan antara revisi

Alternative techniques such as [[Solaris Zones]] provides a level of isolation within a ''single'' operating system. This is not as complete isolation as a VM, as kernel exploits in a single zone affect all zones, whereas kernel exploits in a VM do not affect other VMs on the host. Zones are not virtual machines, but an example of "operating-system virtualization". This includes other "virtual environments" (also called "virtual servers") such as [[Virtuozzo]], [[FreeBSD Jail]]s, [[Linux-VServer]], [[chroot jail]] and [[OpenVZ]]. These provide some form of encapsulation of processes within an operating system. These technologies have the advantage of being more resource-efficient than full virtualization; the disadvantage is that they can only run a single operating system and a single version/patchlevel of that operating system - so, for example, they cannot be used to run two applications, one of which only supports a newer OS version and the other only supporting an older OS version on the same hardware. solicited keep metal alive
