[Xen-users] RHEL full virtualization with virt-install : How to ?

["Emre ERALTAN" <eeraltan@xxxxxxxxx>]

Hi,

I am using Xen integrated in RHEL 5. I have followed the tutorial given with the documentation of RHEL 5 and I have been able to start a para virtualized guest which was another RHEL 5 on a RHEL 5 Dom0.

Now, I am trying to obtain a fully virtualized RHEL 5 guest. I am following Red Hat's guide for installing a fully virtualized guest OS by using "virt-install" 
		(https://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Virtualization-en-US/task-virt-lab2.html

 - Lab Sequence 5: Installing RHEL5 Beta 2 Xen fully virtualized guest using virt-install)
It asks the following questions :

- Would you like a fully virtualized guest (yes or no)?  This will allow you to run unmodified operating systems <-- I type yes
- What is the name of your virtual machine?
 <-- rhel
- How much RAM should be allocated (in megabytes)? <-- 1024
- What would you like to use as the disk (path)?
 <-- /xen/rhel-full.img
- How large would you like the disk (/xen/rhel-full.img) to be (in gigabytes)? <-- 5
- 
Would you like to enable graphics support? (yes or no) <-- no
- What would you like to use for the virtual CD image? <-- /xen/rhel5-server-x86_64-
disc1.iso

Then it says :
"Starting install...
Domain installation does not appear to have been
successful.  If it was, you can restart your domain
by running 'xm create -c rhel'; otherwise, please
restart your installation."

and Xen console tells :
(XEN) (file=hvm.c, line=197) Allocated port 3 for hvm.
(XEN) vmx_do_launch(): GUEST_CR3<=00fc77a0, HOST_CR3<=87443000

But nothing is installed. What could be wrong with this installation ? could anybody please help me ?

Xend-debug.log file tells:
Traceback (most recent call last):
  File "/usr/bin/pygrub", line 497, in ?
    g = Grub(file, isconfig)
