Hi, there's 

First, I would probably delete the "quiet" kernel boot parameter from grub.cfg 
- IIRC it should provide you with much more info during the boot process 
without this parameter, so maybe there will be something interesting. :)
Of course, for what its worth, if you have serial port on the server, serial 
console tend to be quite useful for debugging xen/kernel booting problems - 

And looking at yout grub config from your first email, I don't see the  pure (without Xen) entry there. So are you sure you've tried the non RHEL kernel baremetal (without Xen)? :)

The Photo of the screen isn't all that interesting. There is a cursor that 
stares at you but it isn't very stylish as far as cursors go. ;-)

Anyway I did in fact download the megaraid driver. The package expanded as 
xen-a938a22 .

I ran diff on the build file and the copy placed in /lib/modules, and diff 
reports that they match so the downloaded driver should be in the image.

Has someone had better results with a different kernel or driver.

Is there any way to tell if I need a specialized driver with the IBM version.

I am attempting to install a Xen solution on an IBM X3400.

The raid card is the IBM M1015 which is based on the LSI 9220-8I. I followed 
the directions on the tutorial called "RHEL6 Xen4 Tutorial" at 
http://wiki.xen.org/wiki/RHEL6_Xen4_Tutorial .

When I attempt to boot the kernel the computer freezes. I don't get any errors 
or anything helpful.
I have also attempted to boot the Linux kernel I compiled to use with Xen on 
its own and it behaves the same way. I surmise that there is something wrong 
with how I configured the kernel. Assuming this is the problem I can't >verify 
for sure if the Xen image is functional or not.

I am at a loss as to where to go from here. I'm thinking a different kernel 
maybe or perhaps I have a mistake I just can't see. Can someone offer some 

I am including the grub.conf as a start reference. I can upload any other 
information needed. The Xen entry is the second last while the last entry in 
the Linux kernel on its own. Note this is an UEFI boot and the grub.conf is 
>located in /boot/efi/EFI/redhat/grub.conf while the os images are in /boot .

Hello there,

just few things:

1. it would help if you've posted at least photo of the kernel boot freeze ;)
2. right from the wiki "NOTE! If you're using a system with LSI and/or Dell 
RAID adapters (using megaraid_sas driver) you need to manually update the 
driver version at this point! Linux ships with too old driver 
version, and it wont' work (disks won't get enabled on system startup). See 
this email for information about updating the driver version - 
3. you can try newer kernels  (like 3.2), but i would  bet my 5 pences on the 
previous point (and the Wiki)
