Ok....you saw the details of how I re-built in my prior message in this thread. I added: 8. I went to the kernel directory, and built the kernel from scratch: cd xeno-clone/xenolinux-2.4.22 (edited .config to add ReiserFS support) Did the following: > Do the following: > 1.

Edit xen/common/kernel.c:putchar_console() to remove the initial > if ( !opt_console ) return; then: make dep make make modules (as root) make modules_install (but there were none) make bzImage cd ../.. (to xeno-clone) make install then copied in the new image.gz (xenolinux.gz was unchanged) My grub boot (same as before, but with console=xencons0) grub> root (hd0,0) grub> kernel /xenimage.gz dom0_mem=100000 ser_baud=115200 noht noreboot [output saying "yep, looks like a Multiboot ELF"] grub> module /xenolinux.gz root=/dev/sda2 ro console=xencons0 DOMID=0 [output saying, "yep, it's a module"] The result was the exact same boot I had before -- no extra debugging. The final lines before death: Device eth0 opened and ready for use DOM0: Guest OS virtual load address is c0000000 Other ideas are welcome! -- Greg ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
