(Get the code!)
I've marked this as confirmed and bumped the importance given the impending move to Focal for all testing in the Victoria release.
C#4 is unrelated, I've continued to see detach issues on Bionic while using QEMU 4.0.0 and libvirt v5.0.0 however I've been unable to reproduce outside of upstream CI.
Each time this has been hit however it appears that the Guest OS (cirros) isn't able to react to the ACPI request to detach the disk device. This could simply be another case of the instances needing to be given more resources for these requests to be served quickly enough to satisfy Nova or relaxing the timeout within Nova.
