Virtual Machines

With the module 'VMs' in the 1A-manager you can manage virtual machines (VMs). A VM is a guest computer on a server which runs on mimiced "hardware". The VM can do everything a physical computer can do.

VMs can offer a solution when essential business software can't be installed on the 1A-server. This can happen when the software can only run on another operating system. Savings can be another reason: you don't need a separate physical server for a VM, which saves you power and maintenance.

To be able to boot from a live-CD or to install an operating system on a VM, you often need a physical installation medium (for example a CD, DVD or USB-drive). This medium can be converted to an image which can be connected to a VM with the VM media share. Your 1A-partner can help you with converting a physical medium to a useable image.
