Re: RHEL 4 machine converted fine, but get kernel panic when I start the VM

1. Boot into the RHEL4 rescue environment
2. chroot /mnt/sysimage
3. Edit /etc/modprobe.conf and change the scsi_hostadapter entries to look like this:
   
   alias scsi_hostadapter mptbase
   alias scsi_hostadapter1 mptscsi
   alias scsi_hostadapter2 mptfc
   alias scsi_hostadapter3 mptspi
   alias scsi_hostadapter4 mptsas
   alias scsi_hostadapter5 mptscsih
   
   
4. cd /boot
5. move the current initrd images to another folder or rename them to .old
6. run mkinitrd (example: mkinitrd -v -f initrd-2.6.9.-11.EL.img 2.6.9.-11.EL)
7. Repeat the above step for each kernel (in case you ever decide to boot into them later)
8. Exit the chroot environment
9. Try booting the VM

We ran into this as well and this did the trick.
