This should work: export LIBGUESTFS_ATTACH_METHOD=appliance export LIBGUESTFS_QEMU=/root/work/qemu-wrapper There's an additional problem which is you need the wrapper to distinguish between -help and -version tests and the final command. Use a wrapper like this: ---------------------------------------------------------------------- #!/bin/bash - qemu=/usr/libexec/qemu-kvm if ! echo "$@" | grep -sqE -- '-help|-version'; then echo QEMU debugging enabled. debug="-s -S" fi exec $qemu $debug "$@" ---------------------------------------------------------------------- The wrapper must be executable.
