Hello,
I needed Windows XP virtual machine on OpenSUSE 11.4 (now 12.1). When I looked at YaST, I saw something like “Install Hypervisor and tools”. I tried it, and there appeared several boot-up alternatives in GRUB menu. I find this irritating, and I would like just two (one normal, one failsafe) boot sequences. I am pretty sure I need to edit some files and delete some contents, but I don’t know which file it is and where it is. Currently I am using VirtualBox for my Windows need.
Any help?

If you want to use Xen to run Windows in a VM (DomU) you begin as you did
by installing the Hypervisor. This creates a new Xen kernel. You must run
this Xen kernel if you want to use Xen virtualization.
You still have access to the standard kernel should you need to disable Xen
for some reason. What most people do is simply make the Xen kernel the
default so it boots automatically.

You make the wrong choice “xen” in place of KVM

What Windows need do you have that would require Xen rather then VirtualBox? Btw, you should use KVM, not Xen. But VirtualBox might still be a better choice (faster and smoother desktop).
If you do not want the extra boot entries anymore, you can try uninstalling the kernel-xen package
and if that does not remove the boot entries, you can still run yast2 bootloader to change it.
Btw, you should use KVM, not Xen
Why?
Because KVM is supported by Red Hat and they are actively working to improve it which is not the case with Xen. The other great benefit of KVM over Xen is that You don’t need a special kernel to run it. Just standard linux kernel is enough.

I can (almost) accept the “don’t need a special kernel to run it” argument, but if you are running Xen you could claim that the kernel that does not support Xen is the special one.
Xen has been making inroads in the area of linux kernel integration as well.
As for Red Hat supporting KVM, not much of an argument on an openSUSE forum. As a side note, Oracle’s virtualization product (based on Red Hat) uses Xen instead of KVM. Hmmm.
Xen.org is actively working to improve Xen which is not the case for KVM.
For me, the jury is still out, I’ve been using Xen for 7 years, and see both strengths and weaknesses, for new users, or people that just want to get their feet wet, KVM does have some nice features including, the SPICE display system being faster than vnc on a local system.
It’s really horses for courses, one size does not fit all.
In reference to the original post, it sounds like adjusting the grub entry would be enough to make Bakkurt happy. Just comment out the entries that bug you and be happy.
In my opinion, Bakkurt will probably be happiest using Virtual Box due to the quicker display response, ease of network configuration and simple installation in openSUSE.
Have a good night, see ya,

KVM is included in mainline linux. You just have to install QEMU ans some tools if you need them (such as virt-manager and virt-viewer).
Innotek’s VirtualBox was based on QEMU.
VNC is far too slow. Install NX or FreeNX server on kvm guests. Then you can open desktop sessions from anywhere, including Linux, Windows and Mac OS X clients, and of course from the hosts itself. It is safe, secure and fast - has nothing to do with KVM ; you can install FreeNX on Xen guests too.
Yes. There is absolutely no problem here.
I think you mis-read me (or at least my intention), but I don’t see any benefit in going into a “he said / you said /I said.”
As your last sentence stated…
Yes. There is absolutely no problem here.
have a good night
See ya
ps. I find your “please_try_again” command to be one of open SUSEs most useful tools 
Thanks to everybody who has replied to my post; I have finally found a person who knows how to install and run Oracle VirtualBox, it is now running Windows XP and it seems perfect now. Thank you for all your endeavors.
