The xvp suite consists of 5 components:

• 
  

  xvpappliance

  
  
  

  xvpappliance is a small self-contained virtual machine, that can
  be imported into XenServer or Xen Cloud Platform. It includes xvp,
  xvpdiscover, xvpviewer and xvpweb pre-installed, and has a
  menu-driven interface allowing all of these to be configured easily.
  It has built in scheduling facilities for checking for software
  updates and changes in pool memberships.

  
  
  

  Users can manage virtual machines by pointing their web browser
  at the imported appliance. The administrator of the appliance can
  reconfigure it, as necessary, via a simple menu driven interface,
  that can be accessed from the xvpappliance console or via ssh.

  
  
  

  For most people, installing xvpappliance will probably be much
  simpler than building, installing and configuring the individual
  components separately.

  xvp

  
  
  

  xvp (standing for Xen VNC Proxy) is a proxy server
  providing password-protected VNC-based access to the consoles of
  virtual machines hosted on Citrix XenServer or Xen Cloud
  Platform.

  
  
  

  It can be used to gain access to VM consoles without having to
  run XenCenter, and from any operating system that has a VNC
  client, not just Windows. By suitable use of VNC passwords, it can
  provide delegated access to the consoles of particular virtual
  machines.

  
  



• 
  

  xvpviewer

  
  
  

  This is a custom Java-based VNC client. It is based on the
  TightVNC viewer, but with xvp-specific additions to allow clean
  shutdown and reboot and hard reset to be initiated by clicking
  buttons on the viewer, and with added support for mouse-wheel
  scrolling.

  
  
  

  It is supported on Linux, Mac OS X, Windows, and is also known to
  work on Solaris.

  
  
  

  When used with xvpweb, xvpviewer supports the use of one-time
  passwords, for added security.

  
  



• 
  

  xvpweb

  
  
  

  This is a web-based front end, providing a status view of
  XenServer and Xen Cloud Platform pools, hosts and virtual machines,
  with easy to use facilities to view virtual machine consoles and to
  boot, shutdown reboot, suspend, resume and migrate virtual machines,
  and insert and eject virtual DVD drives.

  
  
  

  It makes use of xvp (running on the same machine as the web
  server) and xvpviewer (supplied in applet form as part of
  xvpweb).

  
  
  

  By making use of a database or flat file, it can be made to
  restrict which users can view and/or manage particular virtual
  machines or groups of virtual machines.

  
  



• 
  

  xvpdiscover

  
  
  

  This is a small program which runs on Linux, and can write a
  configuration file suitable for both xvp and xvpweb.

  
  
  

  It does this by connecting to one of the server hosts in a
  XenServer or Xen Cloud Platform pool, querying the details of the
  pool, hosts, and virtual machines, and generating a suitable
  configuration file based on the information it discovers.

  
  
  

  xvpappliance makes use of a pre-installed xvpdiscover to poll for
  pool membership changes automatically.

  
  

These components can also be used with Xen Cloud Platform (XCP), and
behave in the same way as when used with XenServer.
