"Boot loader didn't return any data!" -- Sisu

[Sisu Xi]

Hi, all:

I am using Ubuntu 12.04, compiled Linux Kernel 3.3.6 from source, Xen 4.1.2 from source.

Downgrade grub2 to grub.

I try to install centOS 6.2, 64bit, para-virtualized as the domU.

When I install it, it goes fine. the configuration file is:

name="centosinstall"
vcpus=2
memory=2048
disk=['file:/home/xisisu/Desktop/VM/vm1.img,xvda,w']
vif=['bridge=xenbr0']
kernel="/home/xisisu/Desktop/vmlinuz"
ramdisk="/home/xisisu/Desktop/initrd.img"
on_reboot='restart'
on_crash='restart'

after installation, when I try to boot it, the configuration file is:
comment out:
kernel="/home/xisisu/Desktop/vmlinuz"
ramdisk="/home/xisisu/Desktop/initrd.img"
add:
bootloader="/usr/bin/pygrub"


when using xl create -c vm.run, it says:
Parsing config file vm1.run
failed to run bootloader: -3
libxl: error: libxl.c:711:libxl_domain_destroy non-existant domain 15
xenconsole: Could not read tty from store: No such file or directory


when using xm create -c vm.run, it says:
Using config file "./vm1.run".
Error: Boot loader didn't return any data!



some googling around says I need to check pygrub,
the command: pygrub /path/to/domu/disk, it says:
Traceback (most recent call last):
  File "/usr/local/bin/pygrub", line 774, in <module>
    raise RuntimeError, "Unable to find partition containing kernel"
RuntimeError: Unable to find partition containing kernel





Can anyone help with this?

thanks in advance.

Sisu

Hi, 

thanks for your reply.

How do I check weather xenconsoled is running? I run xenconsoled and it returned nothing. It seems a debug tool to log guest OS info.

Thanks.

Pygrub is going to look for a grub config on the domU disk xvda (what you've specified as  file:/home/xisisu/Desktop/VM/vm1.img) in a default location, I know /boot/grub/menu.lst works. Then it's going to load the kernel from on that disk like regular grub, so make sure you have the correct path to your kernel and initrd in the menu item.

I think you need to decide whether you want to load the kernel from the domU disk with pygrub or load the kernel from outside with explicit kernel and initrd arguments in the xen configuration file, right now it looks like xen is using pygrub with your current config.

Hi, Chirs:

Thanks for your reply.

I reinstalled the system using CentOS. It's giving me same error
initially. However, when I remove all the *virt*, *qemu* packages, it
seems works fine now.

I don't know the reason for that.

Thanks.
