The setup is three physical machines that host two virtual machines (web frontend and a postgresql database) running by themselves on two of them and another pair of development VMs on the third or the third is powered down as a spare. The VMs rotate between the three physical hosts on every upgrade cycle to spread the wear on drives and the servers. The production images are about 32GB, between 50% and 80% utilized currently, but the remainder of the drives are unused, but dirty, between moves. Can't use fstrim in the VMs because qemu / libvirt doesn't support it yet. signature.asc Description: This is a digitally signed message part ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

It does if you use virtio-scsi instead of virtio-blk; same for scsi passthrough or even fake-hardware emulation of regular scsi.
