Ugg. That's because _qemu_io_wrapper is a shell function, but sudo can't directly invoke shell functions. It passes on systems where $sudo expands to '' because the test is being run as root. I think that test will have to be rewritten to use raw invocation (untested): $sudo "$QEMU_IO_PROG" $QEMU_IO_OPTIONS --format "$IMGFMT" --nocache -c "read 0 65536" "$TEST_IMG" > out 2> err and then manually feed "out" through _filter_qemu_io and replay "err" (since you can no longer take advantage of the '(subshell)|pipeline' trick added by 934659c to force bash to display core dumps). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
