Hello We have the following Configuration Hardware: IBM 346 Dual Xeon 3,4 Ghz 6 GB Ram 4 x 73,3 GB SCSI Disc (Raid5) IBM Serveraid Adapter 7k Software: Debian Sarge Kernel: Modified Debian Kernel 2.6.8 with PAE support, Servraid, Nic and fs Driver build into the Kernel. I tried to install Xen-Stable. Result Unable to mount root Filesystem. I tried to build unstable from source but the result was the same. The Xen Kernel boots. It Seams without PAE which i activated in Config.mk. But thet is a lesser Problem. The Configuration of Grub seems to be correct. title Xen 3.0 / XenLinux 2.6.12 kernel /boot/xen.gz dom0_mem=64000 module /boot/vmlinuz-2.6-xen0 root=/dev/sda1 ro console=tty0 title Debian GNU/Linux, kernel 2.6.8 root (hd0,0) kernel /boot/vmlinuz-2.6.8 root=/dev/sda1 ro initrd /boot/initrd.img-2.6.8 savedefault boot The Kernel 2.6.8 works. The Problem is that i dont see the detection of the Serveraid adpater if dom0 ist booting. so if the Adpater is not recognized the root fs will not be found. Where do i have to configure the Options that the dom0 Kernel uses the Drivers the actual Kernel uses?

You create an initrd the usual way, using ''mkinitrd 2.6.12-xen0''.> Where do i have to configure the Options that the > dom0 Kernel uses the Drivers the actual Kernel uses?As described in the README, you can cd into the linux-2.6.12-xen0 directory in the source tree and ''make ARCH=xen menuconfig''. With the options for building a dom0 kernel turned on (which they should be already) the config is very similar to the standard kernel configuration.

Here I only get that in the -xenU kernel. In the -xen0 kernel, with Privileged Guest (domain 0) and Physical device access turned on in the Xen section, I see all the usual SCSI drivers, including IBM Serveraid. Are you sure you''re editing the right kernel configuration? -- There may come a time The open palm of desire, When I will lose you, ]http://surreal.istic.org/[ The rose of Jericho, Lose you as I lose my sight, Soil as soft as Summer, Days falling backward into velvet night; The strength to let you go. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
