Thanks for all the feedback and pointers! FWIW we were already aware of the discard=unmap option in libvirt, I should have mentioned that. In the meantime I found this bugreport: https://bugzilla.redhat.com/show_bug.cgi?id=1672682 which seems to indicate that this indeed works in libvirt for virtio-blk. So I will continue to figure out why this doesn't work as intended in our setup. -- Mit freundlichen Grüßen / Regards Sven Kieske Systementwickler / systems engineer Mittwald CM Service GmbH & Co.
