I'm unable to detach a disk from a Windows guest using the

Even though 'domblklist' shows the disk attached, and on the FIRST
iteration, it says the command "completed successfully," 'domblklist
will still show the disk attached and subsequent 'detach-disk' commands
fail with 'no disk found whose source path or target is ${location}'

Any ideas as to why this happens?
Sure. There's a difference between live and config XML
https://wiki.libvirt.org/page/VM_lifecycle
detach-disk --persistent removes disk from config XML and domblklist
prints out disks from current state of domain (i.e. if it's running it
prints out disks from live XML).
