That's right!

 With grub2 you really need to duplicate the first entry, like that:

multiboot /xen.gz /xen.gz ...options...

Hello,

I don't know if Xen supports EXT4 but there is another syntax for the
GRUB.CONF file. I found it in the latest versions of grub :

menuentry "GNU/Linux, with Linux xen" {
       insmod ext2
       set root=(hd0,1)
       search --no-floppy --fs-uuid --set
116c3b30-4586-4f25-b7c1-c0d5c5a5b003
       multiboot /xen.gz /xen.gz noreboot dom0_mem=1024M cpufreq=xen
cpuidle
       module  /vmlinuz-xen /vmlinuz-xen root=/dev/md0 ro  noquiet
       module  /initrd-xen /initrd-xen
}

I had to have some values twice (new syntax !) but my boot partition is
still ext3.

Regards

JPPO
