Your final goal may be
implying you don’t want a Dom0. You have to have aDom0 to run Xen. You can
either install Fedora (or as Fajar suggested, CentOS, assuming your hardware
isn’t too new for it), or you can install something like XCP or XenServer,
which have their own more barebones Dom0s (but may require VGA, I am not
familiar with them). I would recommend installing to the USB drive (the same
as Fajar suggested) instead of installing to something else and trying to make
the USB drive behave correctly after the fact, but you could do a minimal install
and then use yum to install Xen, or you could do a minimal install and use yum to
install the necessary compilation tools to compile the latest version. Assuming
you are running 64-bit (and I don’t know why you wouldn’t be), there is also a
repo for CentOS that has later versions of Xen than come with it from yum, so
you could install them instead of compiling or using the stock versions. You should
be able to find that repo by searching the history of this list, or someone may
chime in with the information on it. All of that having been said, I
originally assumed when you said the board was bare, you were implying you
wouldn’t even have a video card, that might get more complicated, but would probably
technically be outside the scope of Xen discussion, and still require you to have
some form of display (attached or otherwise) for the system to think it is
outputting to. I’m not sure what additional advice I could give you, but if
neither Fajar’s response or mine has really directly addressed what you want to
do, feel free to respond and clarify what you want.

Subject: Re: [Xen-users] Xen Installation on Fedora
To follow up I have another question.
MY FINAL GOAL IS TO RUN
THE XEN HYPERVISOR ON A BARE HARDWARE BOARD WITH 2 GUEST OS RUNNING ON
TOP OF IT.
I have an Hardware Board with INTEL CPU running on it with
VT-x, VT-d and SR-IOV support in the BIOS enabled. (Its just a bare
hardware board with only BIOS, nothing else )
I have enabled the USB boot option in the BIOS.
Now here is what I want to do.......
I make a bootable USB drive and copy the Image of Xen to the
USB, plugin the USB key to my Hardware and boot the board with the Hypervisor
Image.
(Is dd command that I need to use to make the bootable USB
and edit the grub file to boot the Xen Image?)
Can anyone let me know if some one has tried this way

The latest
Fedora to come with Xen Dom0 support is 8. This is because it is a
separate kernel. It can be installed with Yum or possibly with a custom
installation, however, F8 has obviously been EOL for some time, so you would
probably be better off going with the source you have already downloaded.
Once pvops dom0 becomes mainstream, the next version of Fedora may support it,
but I don’t know (might ask in a Fedora mailing list). Otherwise you
would be able to compile a custom kernel that supported it (on whatever version
of Fedora came with a new enough version of the kernel to support pvops).
In the meantime, it shouldn’t matter which distro you are using if you are
downloading the source, as the appropriate Dom0 kernel will be (downloaded and)
compiled during compilation of Xen. Even if it seems like a way older
kernel, it should have a lot of newer drivers backported, so don’t panic and
not try it on account of that. Disclaimer: I haven’t actually
done a Xen from source install (or if I have, it has been a really long time),
but I am pretty sure nothing has changed enough to change the accuracy of my
(generally generic) statements above.

Hi,
I
am new to Xen. I have few questions in my mind. Can any one of you
clarify please.
1. Does Fedora
version 10 ,11,12 core has the support for Xen DOM 0 capable kernel
support? Which is the latest Fedora that supports the Xen DOM 0
kernel support? (Based on this I need to select the correct Fedora version to
install for my development environment)
2. Once I
install the Fedora, do I need to invoke “yum “ for installing the
Virtualization support or the default Fedora installation comes with
this. (MY Hardware has support of Intel VT-x, VT-d and SR-IOV though)
3. I have
downloaded latest Xen source version 3.4.2. After I build the Xen
from the source, where or how does the DOM 0 Linux kernel comes from? OR
is that the Linux (in this case Fedora) that I used for building the Xen
becomes the DOM 0 ? I am confused here. I read few documents but I
could not find how this DOM 0 Linux Guest is created?
4.
I am also looking for SR-IOV vf and pf drivers. Xen-3.4.2 include these?
