What is what: XCP-ng, XCP-ng Center, XenOrchestra, XOA, Vates

[borzel]

Hello together,

to avoid more and more confusion about the pieces of the XCP-ng Universe, I'll try to describe what is what.

The Hypervisor, the Host, the Virtualisation Server: XCP-ng

This is the thing you install on bare hardware, it consists of:

• the XEN kernel
• Dom0 - the management domain (it's basicaly a highly custom CentOS with drivers, various services and some glue logic)
• DomU - the VMs, the virtual machines, the things you virtualize
• Love

It's exact the same concept like CITRIX XenServer or CITRIX Hypervisor. XCP-ng is derived from them. Something like a fork, but not so hard.

The basic management software, the windows client, the thing with the tree: XCP-ng Center

EOL-Notice: https://xcp-ng.org/forum/topic/8202/xcp-ng-center-has-come-to-an-end

• community project
  • issues: https://github.com/xcp-ng/xenadmin/issues
  • download: https://github.com/xcp-ng/xenadmin/releases
• some help from Vates

It's derived from CITRIX XenCenter.

The advanced management software, the web client, the backup solution and more: XenOrchestra

• commercial product from Vates
• community driven
  • issues: https://github.com/vatesfr/xen-orchestra/issues
• can be build from sources with all pro features enabled
  • https://xen-orchestra.com/docs/from_the_sources.html
• only community support

It's not derived from anything (as far as I know).

The ready to use XenOrchestra, the appliance: XOA

• single line to install on XCP-ng
• can be licenced with pro features and pro support from Vates
• is a ready to use VM

The company behind: Vates

Olivier Lambert and his company Vates startet all the jazz. They provide pro support for XCP-ng (the host) and XenOrchestra. They help to sign XCP-ng Center and the XCP-ng Windows Client Tools (and drivers) with an proper EV certificate.
