I wonder if libvirt would be changed to accept "discard_granularity='0'" so the traditional hard-disk can be recognized under windows again.
That should be possible, yes. Given the behaviour described above it should be done (although it feels like there is something else that's worth fixing, but I don't know what and where).
Thanks a lot for the good news. it would be a lot easier to setup.
Could you file an upstream (or downstream) issue so that we do not lose track of this?

I will do that asap.
Based on whether it is taking time in the guest or in the host you could theoretically try setting <driver name='qemu' discard='ignore'/> but I guess that would not help.
no it won't help. I had tried that before. I tried many parameters and also tried to set the "media type" manually at windows (the function seems only designed for storage pools, not normal devices). "discard_granularity=0" is the first parameter which is working. I am glad that it works. or I can only stay with very old drivers or replace virtio-blk with virtio-scsi. Regards, tbskyd
