I don't see any evidence of it in my menu.lst. I have built my xen0 kernel with everything static (I don't do a lot of modules). In my .config, I have "CONFIG_BLK_DEV_DM=y" ... shouldn't that take care of it? What's really bizare is that I can create guests over LVM LV's with the same kernel.... Thanks!
