I can confirm the segfault with the same Fedora 1 install. It doesn't
even get to 50%, it segfaults way earlier. In fact I tried this:
- kvm-img create -f qcow2 /store/KVM/test.qcow2 2G
- gi...@voy:~$ sudo LC_ALL=C
PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sn:/sbin:/bin

Thanks for the answers Avi, Juan,

This patchset adds support for the ATA TRIM and SCSI WRITE SAME with
