Xen kernel just not booting

English Install/Boot/Login

After a fresh install of opensuse 11.3 and a xen-hypervisor and tools (all default install, nothing special) just get a black screen when I try to use kernel-xen.
Default kernel runs like a charm.
Xen-kernel gives me a black screen just after grub menu.

This is my menu.lst about it:

Mistery solved.

From /boot/grub/menu.lst :

###Don’t change this comment - YaST2 identifier: Original name: xen###
title Xen – openSUSE 11.3 - 2.6.34-12
root (hd0,2)
kernel /boot/xen.gz vgamode=0x31a vgamode=0x31a

Whay in the hell it has twice vgamode=0x31a !!?? (this is default install config when install xen)
Just let these lines like this:

###Don’t change this comment - YaST2 identifier: Original name: xen###
title Xen – openSUSE 11.3 - 2.6.34-12
root (hd0,2)
kernel /boot/xen.gz vgamode=0x31a

And… thats al falks. “Habemus kernel.xen booting”
:slight_smile:

Next step should be creating and loading some PV Guest for example same Suse 11.3.
I would expect you to get message “Hotplug scripts not working” attempting
to startup guest at Xen 4.0 ( 2.6.34-12-xen) Dom0.

Another way of booting xen kernel (if you have nvidia adapter) is to disable modesetting – just add nomodeset to grub kernel options.
And yes, I get “Hotplug scripts not working” when I try to create domU. Any ideas?

FYI: Another variation on the same problem - SOLVED!

I had same symptoms as vael (black screen after xen-hypervisor install w/ default options following a fresh Opensuse 11.3 install). In my case, the /boot/grub/menu.lst file did NOT have duplicate “vgamode=0x031a” option. Instead, I had “vga=0x031a” specified one-time.

Adding “nomodeset” to the kernel options solved the problem.

Set up Ubuntu Lucid Server PV DomU at Xen 4.0 (kernel-xen-2.6.34.1-0.0.19.40d88ce) on top of opensuse 11.3 « Xen Virtualization on Linux and Solaris
