no Virtualization support for creating VM's on PE840‏

[Odi]

what it is is that i recently purchased a Dell PowerEdge 840 after carefully
selecting the specs i required, on its arrival i noticed that the BIOS does
not support virtualization, as a result of this on successfully installing
Xen vm on Open Suse 10.2 which creates the vm kernel and i try to start the
vm i get the error message:
'Cannot start the virtual machine'
then it goes on to say :
command: /usr/sbin/xm create /etc/xen/vm/vm1 return
  Error: (22, 'Invalid argument')
  Using config file "/etc/xen/vm/vm1".
 
when i prompt for more details i get:

'Error: HVM guest support is unavailable: is VT/AMD-v supported by your CPU
and enabled in your BIOS'
 
i have had a word with dell support who confirmed that the that the BIOS
does not support virtualization for now and that that option in the bios is
defaultly set to disable and that the most recent release of my BIOS
software doesn't list this in the menu for me to toggle that option, and
that maybe a future release of the BIOS software will have accessibilty to
this option. I was adviced by the Dell Engineer to come this site and seek
for help on this site.
 
does anyone know what i can do to get around this problem please.
 
i was told by the Dell engineer to run a cat command on the cpuinfo file to
see if the flag will reflect xt or vt, i did this and the i got the
following:
 
odi@PE840Srv:/proc> cat cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6

constant_tsc pni monitor ds_cpl vmx est tm2 cx16 xtpr lahf_lm
bogomips        : 4269.91
 
i badly need to create virtual machines on this server, its got 750 GB HDD
(mirroring support) and 8GB of RAM, i selected all this with virtualization
in mind obviously. 
 
any assistance will be greatly appreciated.

You CPU stats seems to indicate "vmx" which implies that the CPU us capable
of running HVM hosts. So it is indeed a pity the BIOS does not let you
enable it (for now).

Which OS(s) do you want to run in virtual machines? If you want to run Linux
guests then you don't need to use the hardware VM features - you can run
them in a paravirtualised manner. This is how I run my Linux guests, I only
use HVM for windows or OSs that have not been modified to run in a
paravirtualised configuration.

Hope this helps!

Fred.
