No need to set LIST_KERNELS_DEFAULT, as that sets the default for all clients, and effectively defaults to 486, as it uses LIST_KERNELS_32 in preference to other kernels. LIST_KERNELS_DEFAULT is only useful if you want to override the default, such as with a custom kernel with a different variant name. I would recommend using autodetection, if you have an environment with mixed clients: ltsp-chroot --arch=i386 apt-get install linux-image-amd64 linux-image-686-pae linux-image-486 Add to update-kernels.conf: # Use ifcpu64.c32 to detect 64-bit, PAE or 32-bit machines. PXELINUX_DEFAULT=ltsp-ifcpu64-NBD IFCPU64=true Then it will pick the appropriate kernel at boot. Adjust PXELINUX_DEFAULT to use NFS, NBD, or AOE as appropriate for your configuration. This may give you some small performance improvements on clients with hyperthreading or multiple cores, at the cost of a little more disk space used having multiple kernels. live well, vagrant
