"Free" Hypervisor Options

Since my last post where I described that the xVM Server product is being bundled into xVM Ops Center, I got a lot of questions about whether this means there's no truly open source option for hypervisors from Sun.  Of course, first there is VirtualBox.  There have been over 10,000,000 downloads of VirtualBox and it keeps getting better and better.  However, lots of people are clearly interested in a type-1, bare-metal hypervisor that supports features like multi-CPU guests and migration.

One great option for people that want a completely open source type-1 hypervisor is the xVM hypervisor that's included in every copy of OpenSolaris.  This is the same hypervisor that's at the core of xVM Server, but it's exposed as a feature of the OS instead of as a managed appliance -- all the same base capabilities are there.  It can be a little tricky to get started with xVM hypervisor if you don't have exposure to this style of product.  However, Paul Telles recently put up a couple of blog entries that show everything you need in order to get the hypervisor installed at get your first Windows VM running inside:

but xvm is only 3.1 inside os2008.11, instead of 3.3.1 on official xen website. Do you intend to update soon?

So in other words, Sun will not release xVM Server for Solaris proper? I have a very bitter opinion of xVM Ops Center and how Sun has managed that product. I thought that the xVM Server was going to be made part of the Solaris OS. If my assumption is incorrect, I have some explaining to do to my boss.

@gerard: Yes, the Solaris team is working on integrating the newest Xen revisions. You can watch discussions here for details: http://opensolaris.org/os/community/xen/discussions/

@Alex: There are a lot of terms here that can get confusing. xVM Hypervisor is included in OpenSolaris. See the links above for all the details. xVM Server is a specialized distribution of OpenSolaris that includes additional manageability bits that link it to Ops Center (similar to the way VMware ESX links up to Virtual Center). Either xVM Hypervisor or xVM Server can run any guest OS including: Solaris, OpenSolaris, Windows, Linux, etc...

I assume the information at http://xvmserver.org/download.html needs to be updated, then...?

Does this mean the XVM built in web interface will be made available in OpenSolaris or is this going to be reserved for Ops Center customers?

How about Xen Hypervisor into Solaris 10 OS ? any plan ?

For Solaris 10 OS is an enterprise, commerical OS, we would like to build Virtualiztion solution(Windows, Liunx, Solaris OS) on Solaris 10 OS platform rather then Open Solaris.

I agree, for us we need to deploy a hypervisor solution in a commercial grade version of Solaris with a good management solution, does this mean that XVM Ops Center is my only option or will I be able to get a Sun Supported version of Solaris which comes with a Hypervisor and browser based management interface?
Is pricing information for XVM Ops Center available somewhere?

The xVM server documentation and Sun SE led us to believe that we could not do cpu pinning or migration without OPs Center. Since there is no academic pricing for OPs center we went with Centos xVM on our x4600 which does support both.

Is Sun xVM on OpenSolaris really less featured than the Centos (from Redhat) free version?
