Re: [Xen-users] please help: Linux Kernel must be loaded before initrd

["Olivier B." <xen.list@xxxxxxxxx>]

Hello

> kernel /xen.gz-2.6.18-128.1.10.el5 ro root=/dev/VolGroup00/LogVol01 
ide0=noprobe ide1=noprobe
> initrd /initrd-2.6.18-128.1.10.el5.img

The first line load Xen and the second load Initrd ; where do you load 
Linux ?
You should have :
1 : kernel /path-to-xen
2 : module /path-to-linux
3 : module /path-to-initrd
