Hi,
I've always wanted an open source client for Xen and VMWare. I was delighted
when I found this. Yet to find a VMWare Vsphere client alternative.
OpenXenManager (aka OpenXenCenter) is a client application to connect to the
XenServer Host through the network. OpenXenManager is a open source clone of
Citrix's XenServer XenCenter. OpenXenManager is written in python with pygtk
and a and gtk-vnc (or vncviewer). You can monitor your virtual machines,
access virtual machine consoles, perform allowed operations (start, stop,
suspend, reboot...), create virtual machines, and more.
