Hi All,

I am using Xen hypervisor for my class project. I need to boot DomU from my custom kernel. I have compiled the kernel code inside DomU and created the initramfs. I can see its entry after update-grub. But when I reboot, I am getting following error:
Error: Boot loader didn't return any data!

Here is my config file (ubuntu.cfg) :-
name = "ubuntu"
memory = 1024
disk = ['phy:/dev/VG/ubuntu,xvda,w']
vif = ['']
#kernel = "/var/lib/xen/images/ubuntu-netboot/vmlinuz"                                                                                       
#ramdisk = "/var/lib/xen/images/ubuntu-netboot/initrd.gz"                                                                                    
#extra = "debian-installer/exit/always_halt=true -- console=hvc0"                                                                            
vcpu = 4

If you commenting these 3 lines then your DomU didn't have any boot loader. Try to add pygrub on your domU configuration file.

bootloader = "pygrub"

I have initially uncommented these 3 lines to create DomU. Once DomU was ready I commented out these 3 lines and launched vm using following command:
xm create ubuntu.cfg -c

Please some one help asap as my project deadline is approaching fast.
