Well here is how I built my initrd's for an older kernel
(for what its worth):

#mkinitrd -v -f -with=aacraid --with=sd_mod --with=scsi_mod \
initrd-2.6.16.13-xen.img 2.6.16.13-xen

#cp initrd-2.6.16.13-xen.img /boot

Note that this isn't a Xen thing so much as a general Linux thing.
Googling for initrd should help you out.

Steve -

Thanks for the information, I realize thats a linux thing, not a xen thing, as i used to have to create one in order to boot an old 440GX MB sometime ago. i DO however see these initrd's in /boot:

initrd-2.6.19-1.2911.6.5.fc6xen.img
initrd-2.6.19-1.2911.fc6xen.img

so they are there. This may sound like a stupid question but where exactly am i using these? They are already called out in dom0's grub.conf. Sorry, i am a little confused here....
