Xen users - May 2007 - Operative system supported in virtual machines by Xen 3

Hi,

my question is: which operative systems in the virtual machines are
supported by Xen 3.0 ?
For example: can I have a Fedora Core 6 with Xen 3.0 and create 3
virtual machine whith Windows Server 2003, RedHat ES5 and Ubuntu
respectively installed for production enviroenment?

Thanks for your answers.

If your hardware has virtualisation support (Intel''s VT-x or AMD-V)
then you
can probably run all the operating systems you list.  If you don''t,
then
you''re limited to paravirtualised guests (i.e. just the Linux guests,
not
Windows).

I''m not sure what Xen version FC6 ships.  I think it might be 3.0.3,
which was
a little lacking in HVM (full virtualisation) support.  Installing 3.0.4, or 
maybe 3.1 would get you better HVM support and might make it smoother trying 
to run the Windows guest.

Redhat ES5 and Ubuntu can then be configured to run paravirtualised on this 
host, with Windows running in an HVM domain.  HVM support for Windows in 
general has come along quite nicely but I''m not sure if 2003 is
"officially"
supported.

I''ve had no stability trouble running Win XP (I''ve had some
issues with Vista
but that may not be all Xen''s fault).  It''s not especially
fast, but it
serves my needs well.  The only problem I''ve had is that after
upgrading to a
xen-unstable snapshot Windows decided that my virtual hardware had changed 
and now wants to be reactivated :-(

You''ll want to do your own production-readiness evaluation, but from
what I
understand, Xen looks like it may well serve your needs.  The XenSource Xen 
products also supply accelerated disk / net drivers for Windows - you could 
try XenExpress as a cost-free example of what this is like (and I believe you 
can upgrade that seamlessly to XenServer / XenEnterprise by buying a license 
key).

Cheers,
Mark

Yes, you can.

But! You must note that you can run Windows OS inside domUs
only if your CPU is HVM-capable.

Please, take a look at this:

* http://wiki.xensource.com/xenwiki/OSCompatibility 
(this is about OS you can run in the Xen domains)

and at this:

* http://wiki.xensource.com/xenwiki/HVM_Compatible_Processors
(this is about CPU that you need to run Windows in the Xen domains)
