virt-install/libvirt defaults to IDE for disk devices (as does directly
launching qemu or kvm). These disks will show up in a RHEL5 guest as
/dev/hda, etc. In newer distros, these disks show up as /dev/sda, etc.
It's just a matter of the RHEL5 stack being older than the hdX -> sdX
change.
If you want to use scsi disks via virt-install, you can use:
virt-install --disk ...,bus=scsi
Though AIUI it's generally considered buggy at the qemu level, and may
even be disabled in RHEL5.4
