NAME

libguestfs-test-tool - Diagnostics for libguestfs

SYNOPSIS

 libguestfs-test-tool [--options]

DESCRIPTION

libguestfs-test-tool is a test program shipped with libguestfs to allow you to check basic libguestfs functionality is working. This is needed because libguestfs occasionally breaks for reasons beyond our control: usually because of changes in the underlying qemu or kernel packages, or the host environment.

If you suspect a problem in libguestfs, then just run:

 libguestfs-test-tool

It will print lots of diagnostic messages.

If it runs to completion successfully, you will see this near the end:

 ===== TEST FINISHED OK =====

and the test tool will exit with code 0.

If it fails (and/or exits with non-zero error code), please paste the complete, unedited output of the test tool into a bug report. More information about reporting bugs can be found on the <http://libguestfs.org/> website.

OPTIONS

--help: Display short usage information and exit.
--qemu qemu_binary: If you have downloaded another qemu binary, point this option at the full path of the binary to try it.
--qemudir qemu_source_dir: If you have compiled qemu from source, point this option at the source directory to try it.
-t N
--timeout N: Set the launch timeout to "N" seconds. The default is 600 seconds (10 minutes) which does not usually need to be adjusted.

TRYING OUT A DIFFERENT VERSION OF QEMU

If you have compiled another version of qemu from source and would like to try that, then you can use the --qemudir option to point to the qemu source directory.

If you have downloaded a qemu binary from somewhere, use the --qemu option to point to the binary.

Note when using these options, you can ignore the business of qemu wrapper scripts (``QEMU WRAPPERS'' in guestfs(3)), since libguestfs-test-tool writes a wrapper script for you if one is needed.

TRYING OUT A DIFFERENT KERNEL

If you are using febootstrap ≥ 3.8 then you can select which kernel libguestfs tries. You do this by setting the environment variables "FEBOOTSTRAP_KERNEL" and/or "FEBOOTSTRAP_MODULES".

Refer to ``ENVIRONMENT VARIABLES'' in febootstrap-supermin-helper(8) for further information.

SELF-DIAGNOSIS

Refer to ``APPLIANCE BOOT PROCESS'' in guestfs(3) to understand the messages produced by libguestfs-test-tool and/or possible errors.

EXIT STATUS

libguestfs-test-tool returns 0 if the tests completed without error, or 1 if there was an error.

ENVIRONMENT VARIABLES

For the full list of environment variables which may affect libguestfs, please see the guestfs(3) manual page.
