I''m just starting to look at getting a HVM running myself
(that''s an "I''m
not an expert disclaimer" :> )

I didn''t think that "xm create" would say anything beyond
that.

If you do a "xm list" does it show up the HVM domain? Maybe
it''s just
sitting around running in the background waiting for a VNC connection or
somesuch.

Seeing as I was after one anyway I gave your config a go.
It does *indeed* pop up a window briefly - whatchaknow
:)

boot from and shuts down.

There does seem to be something about a CDROM in the window that pops up,
but I don''t read quite *that* quickly.

If I get it going I''ll post back here.

The xen cdrom config seems to have changed, or at least it''s pickier
than
I''d like.

Here are the non-comment bits from my config that seems to be working.

import os, re
arch = os.uname()[4]
if re.search(''64'', arch):
    arch_libdir = ''lib64''
else:
    arch_libdir = ''lib''
kernel = "/usr/lib/xen/boot/hvmloader"
builder=''hvm''
memory = 128
shadow_memory = 8
name = "winxp"
vif = [ ''type=ioemu, bridge=xenbr0'' ]
disk = [ ''file:/extra/xen/hvm.img,hda,w'',
''file:/extra/xen/hvm-cdrom.iso,hdc:cdrom,r'' ]
device_model = ''/usr/'' + arch_libdir +
''/xen/bin/qemu-dm''
sdl=1
vnc=0
stdvga=0
serial=''pty''

Hello,
  I will give it a try in a couple of hours as I am right now not close to that
machine with the processors with VT support.

May I ask - is your disk is a SATA disk on non-SATA? (this is for the
disk = [ ''file:/extra/xen/hvm.img,hda,w'', line, which in my
case is
disk = [ ''file:/var/lib/xen/windisk.img,ioemu:sda,w'' ]).


And :
Did you succeed in installing windows with this config file ?
Did you succeed in running windows under Xen ?

I am quite surprised that there is not (yet) an HowTo on this , which
seems to be a popular task theses days under FC6.

Regards,
Ian

My disk is a SATA, but I don''t think that matters much as I''m
just using a
file based disk device. I think that second tag tells the HW emulation
layer what to present the device as to the guest operating system, so you
should be able to present the disk image file as SDA if you like but it
would only affect what sort of drivers windows uses to talk to the
emulation layer.

They may have to match if you''re presenting the guest with real
partitions
(which gives better performance), not sure.

If you''re wanting to point it at a real CD-ROM you put in something
like
 ''phy:/dev/cdrom,hdc:cdrom,r'' instead of the iso.

Yes, seems to work fine.

Good luck,
Robert

If anyone wants to write one - feel free to add it in the Fedora Project
wiki - there is a general Xen + FC6 guide you can either add to directly,
or link to a new page from

http://fedoraproject.org/wiki/FedoraXenQuickstartFC6
