OK, so the install CD unplug the emulated devices and the PV drivers
got activated. Now when you boot your guest are using

root=/dev/xvda1
or
root=UUID=xxxx
or
root=/dev/hdaX
?

And when you do boot that guest, what is your output? You can
get it easily by doing something like this:

kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory=1024
maxvcpus = 3
serial='pty'   ; <========= MAKE SURE TO HAVE THAT
vcpus = 2
name="bootstrap-x86_64-pvhvm"
disk = [ 'file:/mnt/lab/bootstrap-x86_64/root_image.iso,hdc:cdrom,r','phy:/dev/guests/bootstrap-x86_64-pvhvm,xvda,w']
boot="dn"
vif = [ 'mac=00:0F:4B:00:00:68, bridge=switch' ]
vnc=1
vnclisten="0.0.0.0"
usb=1


And do 'xm console <guest>", and run 'vncviewer localhost:0'
and in the GRUB entry add this to your Linux stanza:

"console=ttyS0,115200 debug loglevel=8 initcall_debug".

That will pipe your guest output to 'xm console'. From there it should
be possible to figure out why the disks aren't seen.

Oh wait, you are using 'virt install' do this right? Then to
get that .xm file, do something like this:

[root phenom bin]# virsh dumpxml F17 > /tmp/f17.xml
[root phenom bin]# virsh domxml-to-native xen-xm /tmp/f17.xml
name = "F17"
uuid = "f15e454d-3ec3-1e8c-29d6-8dfe58e6e9a1"
maxmem = 1024
memory = 1024
vcpus = 1
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
vfb = [ "type=vnc,vncunused=1,keymap=en-us" ]
disk = [ "phy:/dev/vg_guest/f17_32,xvda,w" ]
vif = [ "mac=00:16:3e:fa:8f:9c,bridge=switch,script=vif-bridge,vifname=vif70.0" ]

[I am here using a PV guest, but you should be able to
the same with your HVM guest and add that 'serial='pty''
option], and then start the guest using 'xm create <your newly edited file>'

Virtual Box .. Hm, I wonder what it does differently. Wait, are you installing
a new guest or trying to make it work under Xen?
