I am trying to boot a XenU into kickstart under Scientific Linux 3.0.5 (I don't _really_ need to but it would be nice to have the option!) I've got something like this in my Xen config:

kernel = "/boot/vmlinuz-2.6.9-xenU"
ramdisk = "/var/xen-grid/gridui02/initrd.img"
memory = 256
name = "gridui02"
disk = [ 'file:/var/xen-grid/gridui02/fs/root,hda2,w',\
'file:/var/xen-grid/gridui02/fs/swap,hda3,w' ]
extra = 'ks=http://gridinstall02.testgrid/ks/gridui.testgrid.ks ksdevice=eth0 ramdisk=131072'

where the initrd.img is a kickstart one. It seems to boot OK but then I get the message:


+----------------+ Error +----------------+ | | | You do not have enough RAM to install | | Scientific Linux on this machine. | | | | +----+ | | | OK | | | +----+ | | | | | +-----------------------------------------+

This happens regardless of how much memory I assign to the VM. The kernel boot messages seem to report the available memory OK:

Memory: 800980k/819200k available (1596k kernel code, 18168k reserved, 466k data, 92k init, 0k highmem)

Any ideas on how the memory check is being performed and why it's failing?
