Description of problem: Start RHEL5.6.z guest with "-cdrom /dev/sr0" when host no media inserted, login guest, some error happens in dmesg. Version-Release number of selected component (if applicable): guest kernel:kernel-2.6.18-238.5.1.el5 host qemu:qemu-kvm-0.12.1.2-2.113.el6_0.8.x86_64 How reproducible: 100% Steps to Reproduce: 1.start guest with host cdrom when host no media inserted # -cdrom /dev/sr0 2. login guest, check cdrom # ll /dev/cdrom lrwxrwxrwx 1 root root 3 Mar 7 04:47 /dev/cdrom -> hdc 3.
