The error you are getting is probably due to a malformed ramdisk<br>
for your Xen kernel. Likely what is happening is that the ramdisk<br>
is trying to load the real scsi device as sda1 rather than the xenblk<br>
block device. Try to replace the ramdisk and see if you do any better.<br>
I had this same error a while ago and building a ramdisk on a xen<br>
VM that was installed statically is what it took for me to make it work.<br>
<br>
Also, just so you know, when you say KERNEL = /boot/vmlinuz....<br>
etc, then the kernel and ramdisk have to be in that location<br>
on your VM host, not inside the LVM you are trying to boot.<br>
If you want to use the kernel/ramdisk inside the xen virtual machine<br>
then you should use pygrub, which is what I use.<br>
