The Turnkey Linux Virtual Appliance Library is an open source project developing a free virtual appliance library of pre-packaged servers based on Ubuntu that can be deployed on virtual machines, in cloud computing infrastructures or installed in physical computers.
Each virtual appliance is a ready-to-use solution that's optimized for ease of use in server-type usage scenarios.Each appliance is designed to "just work" with little to no configuration required.
The project currently maintains 40 virtual appliances, which are packaged in multiple build formats:
- Amazon Machine Image: provisioned on-demand via the Amazon Elastic Compute Cloud.
- Virtual appliance: a ready-to-run VMDK disk image with OVF support. Does not require installation.
- Installable Live CD: an ISO image which installs on both bare metal (I.e., a non-virtualized physical machine) and virtual machines, including VMware, Xen, VirtualBox, and KVM. This image can also run live in non-persistent demo mode.
