Starting qemu-kvm hangs too, i think it's the same Bug. Strace on the hanging qemu-img ends on: select(5, [4], [], NULL, NULL) =3D 1 (in [4]) read(4, "\0", 16) =3D 1 close(3) =3D 0 open("test.img", O_RDONLY|O_NONBLOCK) =3D 3 fstat(3, {st_mode=3DS_IFREG|0644, st_size=3D131072, ...}) =3D 0 close(3) =3D 0 open("test.img", O_RDONLY|O_NONBLOCK) =3D 3 fstat(3, {st_mode=3DS_IFREG|0644, st_size=3D131072, ...}) =3D 0 close(3) =3D 0 stat("test.img", {st_mode=3DS_IFREG|0644, st_size=3D131072, ...}) =3D 0 open("test.img", O_RDWR|O_CLOEXEC) =3D 3 lseek(3, 0, SEEK_END) =3D 131072 next line in the strace on working qemu-img V0.15.1 is: pread(3, "QFI\373\0\0\0\2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\20\0\0\0\0\0\0\0\= 0"..., 512, 0) =3D 512 ... The only linking difference i see is the libgthread on the new version V1.0. I am using glib V2.26.
