Reproduced this issue on kernel-2.6.32-195.el6.x86_64, qemu-kvm-0.12.1.2-2.193.el6.x86_64. When I do "# eject -t /dev/sr0", the result is "eject: CD-ROM tray close command failed: Input/output error".
Verified it on the fixed version kernel-2.6.32-211.el6.x86_64, qemu-kvm-0.12.1.2-2.199.el6.x86_64, the tray was closed successfully.

steps：
1.start the RHEL 6.1 guest.
2.In guest, take actions as following:
# eject /dev/sr0
# eject -i on /dev/sr0
# eject -t /dev/sr0

Actual results:
The tray was closed successfully.

Above all, this issue has been fixed.
