NAMElibguestfs-test-tool - Diagnostics for libguestfs
DESCRIPTIONlibguestfs-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:
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.
- 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 QEMUIf 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 KERNELIf 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-DIAGNOSISRefer to ``APPLIANCE BOOT PROCESS'' in guestfs(3) to understand the messages produced by libguestfs-test-tool and/or possible errors.
EXIT STATUSlibguestfs-test-tool returns 0 if the tests completed without error, or 1 if there was an error.
ENVIRONMENT VARIABLESFor the full list of environment variables which may affect libguestfs, please see the guestfs(3) manual page.
