Yes, grub was completely re-installed using Knoppix: $ grub > root (hd0,0) > setup (hd0) and the device.map was updated. On power up, grub loaded the kernel just fine and the kernel ran. What the kernel didn't do was hand over control to init. It couldn't do that because root "/" wasn't mounted, and root wasn't mounted because vgchange didn't notify the kernel of any logical volumes (LVs) because vgscan didn't find any. What's odd is that if I boot with Knoppix and run vgscan, it does find LVs. It's almost as though the Red Hat kernel isn't loading the drivers for the SCSI controller. Another look at the screeshot shows that insmod exited abnormally when it tried to load the sym53c8xx.o module. No SCSI driver, no devices. No devices, no LVs. No LVs, no root. No root, no /sbin/init. No /sbin/init, kernel panic. That seems to make sense, but is that really what's happening? I'll try two things: 1) copy over the kernel and initrd again. Maybe they got corrupted. 2) failing #1, I'll convert the virtual disks from SCSI to IDE. Just to clarify, there wasn't a RAID on the original system. The system was combining two drives (more correctly, the free space on two drives) into a single device using LVM. Also, the VM drives were setup to be SCSI, not IDE, just like the original equipment. The original equipment is old server hardware running Red Hat 9 (not Red Hat Enterprise Linux and not Fedora 9). Any other ideas, thoughts, suggestions?
