Have you checked into Xen specifically and how it works?
I am currently researching how Xen works. I am finding the top-level
information a bit lacking in low-level information.
I came across the website with all the objects for Xen, however, I
have yet to find implementation or developer information, so I still
have some digging to do, obviously.
I have downloaded the pdf information, however, I have not gotten far
enough into the docs to figure out what is actually needed to have Xen
function as it should on FreeBSD.
I am also researching the different types or products to figure out
what should be my target for the most investigation.
I think you're where I was at a while ago, and a little investigation
will
change your mind.FWIW Xen is a hypervisor, and platforms need to be
able to run in it, not the other way around. Have a read up on it
anyway.
I am still premature in my research of this platform, so I am still
trying to figure out what is done by the Xen implementation that is
not within the indigenous OS. (I assume that it encapsulates
environments as would be needed for true virtual private services.)
Thanks for the dialogue, I am still very much premature in my research
of this "virtualization appliance" project that I thought up for my
environment, and it is nice to see some feedback.
Have you checked the Xen site? Its actually a Citrix product if that helps.
It gets confusing I know- check out wikipedia as well. That will help I
think. And the Xen site (if I remember correctly) is designed with EU's-
in mind not high-level CTO's jargon.
For a start though, something like VMWare and VirtualBox run as an app
on a host (like FBSD). Xen actually runs on the hardware and the guests
run on it. Hence the only project for FreeBSD is for dom0- as special
emulated cpu on Xen.
Thats why Xen usually gets rated faster- its not actually on an OS
because it is one. Thats classified as a type 1. The others have to go
through the host OS first to get something, so it slows them down just a
bit, though the kernel modules help that quite a bit.
HTH clear the fog a bit :) But definitely check out the Xen site- you
can even download the iso to test.
