I've downloaded this version of the Debian installer: http://ftp.nl.debian.org/debian/dists/etch/main/installer-i386/current/images/netboot/netboot.tar.gz In my domU, the installer reports that no disks are found. If I run a shell from the installer menu, I can successfully partition the disk /dev/sda from the command line, using fdisk I suspect that the Debian installer wants to access the disk using a devfs name. How do I either a) get the installer to use /dev/sda or b) force my Xen kernel to create the devfs device nodes? The dom0 system is lenny, Xen 3.2, current versions of the packages, it was only installed yesterday. Nothing has been compiled in-house. The initrd has had the modules added to match the Xen kernel, otherwise it's content is identical to the netboot initrd. Configuration file used to create domU: kernel = "/boot/vmlinuz-2.6.18-6-xen-686" ramdisk = "/boot/initrd-xen-debian-installer.gz" memory = 512 name = "test1" vif = [ 'bridge=eth0' ] disk = [ 'phy:/dev/mapper/daniel_vg-dom1_root,sda,w' ] root = "/dev/sda1 ro vga=normal console=tty0 devfs=mount,dall" This message and any files attached are intended solely for the use of the individual or the entity to whom they are addressed and may contain information that is confidential.
