Fixed by upstream commit e3843d7f. Move to POST. I can also reproduce this bug with cdrom and an ISO file with specific name. Verify pass on libvirt-0.9.13-3.el6.x86_64 qemu-kvm-0.12.1.2-2.298.el6.x86_64 kernel-2.6.32-289.el6.x86_64 Do test # virsh attach-disk vr-rhel6u3-x86_64-kvm /var/lib/libvirt/images/local.img vdb Disk attached successfully # virsh detach-disk vr-rhel6u3-x86_64-kvm vdb Disk detached successfully # virsh attach-disk vr-rhel6u3-x86_64-kvm /var/lib/libvirt/images/attch.img vdb Disk attached successfully # virsh detach-disk vr-rhel6u3-x86_64-kvm vdb Disk detached successfully no problem Also according to comment 4, do testing # virsh change-media 2 hdc /var/lib/libvirt/migrate/RHEL6.2-20111117.0-Server-x86_64-DVD1.iso --insert succeeded to complete action insert on media # virsh change-media 2 hdc --eject succeeded to complete action eject on media no problem Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: If using local.img or attch.img as a image name then hot-plug the disk into guest, it's okay, however, it will be failed if hot-unplug the disk from the guest. Other special image name also should meet the problem, but I'm not sure what they are, at present, 'local.img' and 'attch.img' also can reproduce the issue. Version-Release number of selected component (if applicable): # rpm -q libvirt qemu-kvm-rhev kernel libvirt-0.9.10-21.el6.x86_64 qemu-kvm-rhev-0.12.1.2-2.293.el6.x86_64 kernel-2.6.32-220.el6.x86_64 How reproducible: always(using 'local.img' or 'attch.img' as a image name) Steps to Reproduce: 1. # qemu-img create /var/lib/libvirt/images/local.img 10M Formatting '/var/lib/libvirt/images/local.img', fmt=raw size=10485760 2. # virsh start <domain> such as domain is 'myVM' 3. # virsh attach-disk myVM /var/lib/libvirt/images/local.img vdb 4. # virsh detach-disk myVM vdb Actual results: # virsh attach-disk myVM /var/lib/libvirt/images/local.img vdb Disk attached successfully # virsh detach-disk myVM vdb error: Failed to detach disk error: (device_definition):7: Extra content at the end of the document </disk>� -----------^ Expected results: fix it. Additional info: It seems virsh/libvirt can't deal with some special key words image name when running virsh detach-disk.
