SYNOPSISlibguestfs-test-tool [--options]
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:
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.
-V
--version
Display the libguestfs version number and exit.
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 STATUSlibguestfs-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.
