Hello,

I will try and answer some of your questions as best I can.

First there will usually be some problems with the RPM xen kernels that
are installed through YUM. If you want a custom setup (with certain
drivers) you should try compiling from source or trying a kernel
recompile and ensure that the Graphics card drivers are compiling as
modules as well as any other modules relating to your graphics card. 

The best thing to do is boot up each system then do an lsmod in each and
compare.

As for your other question regarding the Fedora VM, did you see the
installation process go through? From a console type "xm list" to view
the VMs and type xm console <whatever your vm is named, not Domain0>
then press enter to see if it is live.

If it isn't then it didn't install properly. I personally don't use
virt-manager because the command line works just as well or even better.
That blue console seems to be just the default and probably isn't even
connected to the newly created VM.

Virt-manager will not work without a Xen Hypervisor enabled kernel (so
the kernel you boot with -xen on the end is the proper one). 

For your ftp setup it is probably best that you do a Paravirtualized
environment. I have some documentation on it and there is tons around
the web, what OS were you thinking of installing? There are tons of
guides on installing a Debian guest using xen-tools.

Yes, you can have a virtual instance of Windows XP. Google is your
friend for that one but if you get really stuck, the very knowledgeable
people in here can give you a hand for sure.

An easy way of finding your DVD device would be to pop a CD in the drive
and when it opens in Gnome or KDE press open to view files (or whatever
it is called) then go to a console and type "mount". It will list a
bunch of things but there should be one that will say something with
/media/DvdTitle if I am not mistaken and the device name should be
before that.

Good luck! I hope I answered most of your questions, if you have any
more or would like me to be clearer, let me know.

Cheers,
Tait Clarridge

Subject: [Xen-users] Sup guys, I'm a Xen noob, I have plenty of
questions...


I'm running Fedora 8 on an E6300 OC'd to 2.5 GHZ, 2 gigs of DDR2 Ram,
around
950GB on a raid0.  I have 2 main partitions, 600GB nfts for windows xp
and
300GB ext3 for Fedora 8, and 2GB swap.  Anyhow, I use Fedora most of the
time.  So here is what I've done so far.  I yum installed kernel-xen xen
and
virt-manager.  I rebooted to the xen os.  When I booted into the
Desktop, I
noticed that my windows were all out of whack (I have compiz fusion
installed on my regular Fedora 8 OS).  So I deactivated desktop effects
and
everything worked fine.  I noticed that my kmod-nvidia driver was no
longer
installed.  Can you guys explain what this OS is?  It seems to be a
duplicated of my normal Fedora 8 OS but only that my nvidia driver isn't
loaded.  So, if I wanna run an OS and a virtual OS, I have to boot up to
this OS? the one with xen at the end?  I tried installing the
kmod-nvidia
driver but it didn't install because it said that the kernel was already
installed.

Ok, so I used the gui virtual machine manager and created a virtual OS
of
Fedora 7, I made it paravirtual, gave it 10GB, and 512MB of Ram, and
created
a virtual network.  After it installed I could see the blue console.
Now
I'm a bit confused.  Is the Installation complete?  It never said that
the
installation was complete, but nothing is happening.  What can I do with
this blue console?  How do I run programs on it?  I mess with the
virtual
machine manager and see how my new virtual os is taking up cpu usage.
So I
rebooted the computer back to the original Fedora 8 OS.  I try using
virtual
machine manager, but it won't connect, it says that my libvirtdaemon
hasn't
started.  So I reboot to the Fedora 7 xen OS.  I go to virtual machine
manager and try to connect to my virtual os.  It starts up and it says
it's
running, but there's no cpu usage.  I check the console, and it says
it's
currently unavailable.  It won't let me pause the virtual os, says that
the
POST operation failed, bootloader didn't return any data.  What do I
need to
do to get the virtual os to start running again?

Much thanks for helping out guys.  I'm just confused.  I wanted to use a
virtual os to setup and ftp server, but I just don't see how one can do
so
with that blue console.  I'm obviously missing something.  Should I have
gone virtual instead of paravirtual?  Also, I've heard that once I get
the
virtual os running, I can switch between my regular Fedora 8 OS and my
virtual Fedora 7 OS with a simple click of the mouse.  Is this true with
Xen
or should I use another virtualization program.  Also, I have the
Vanderpool
Technology activated in the bios, fyi.  Also, can I have a virtual os of
windows xp?  Like where it had asked me about the installation media, if
I
had provided windows xp media, would it have worked?  Also, how do I tie
a
linux install dvd to nfs?  I know that in order to do this, I need to
find
out where my dvd is mounted.  How do I find that out?  I've been going
to
/dev and searching there, how do I know which one is for my dvd player? 
Would it be /dev/dr0/ /dev/sdc?  Anyhow, thanks.

I've been retrying the virtual os installation and a blue screen comes
up
and asks me to put in the web server and fedora directory.  I've been
using
http://fedora.tu-chemnitz.de/pub/linux/fedora/linux/releases/7/Fedora/i3
86/os/,
but I guess I need another one.  Any of you guys have any media http
links
to Fedora 7 or 8?
