I'm trying to get Xen up and running on a dual-processor i686 box. For reference purposes, here is the grub.conf entry that I use to boot the normal SMP kernel: title Fedora Core (2.6.16-1.2080_FC5smp) root (hd3,4) kernel /vmlinuz-2.6.16-1.2080_FC5smp ro root=/dev/md1 \ acpi=off apm=power-off hda=3649,255,63 \ hde=21889,255,63 hdg=14593,255,63 hdi=14946,255,63 \ hdk=14946,255,63 vga=775 initrd /initrd-2.6.16-1.2080_FC5smp.img And here is the grub.conf entry for Xen: title Fedora Core (2.6.16-1.2080_FC5xen0) root (hd3,4) kernel /xen.gz-2.6.16-1.2080_FC5 com1=9600,8n1 acpi=off debug module /vmlinuz-2.6.16-1.2080_FC5xen0 ro root=/dev/md1 \ acpi=off apm=power-off hda=3649,255,63 \ hde=21889,255,63 hdg=14593,255,63 hdi=14946,255,63 \ hdk=14946,255,63 console=ttyS0,9600n8 console=tty0 \ debug init 3 module /initrd-2.6.16-1.2080_FC5xen0.img Booting fails when the xen0 kernel can't find init: md: ... autorun DONE.
