Actually I wonder what the expectation is.

The QEMU driver only implements a very limited form of the
virDomainAttachDevice call (merely allowing you to signal that the
CD-ROM has been replaced) and doesn't implement virDomainDetachDevice
at all, so there is no example to go on there.

Maybe better to document what the behaviour is supposed to be in
src/libvirt.c?  After all you can effect a permanent change to the
device configuration by using virDomainDefineXML.

Just my 0.02$
