.IX Header "説明"
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.
.PP
If you suspect a problem in libguestfs, then just run:
.PP
.Vb 1
\& libguestfs\-test\-tool
.Ve
.PP
It will print lots of diagnostic messages.
.PP
If it runs to completion successfully, you will see this near the end:
.PP
.Vb 1
\& ===== TEST FINISHED OK =====
.Ve
.PP
and the test tool will exit with code 0.
.PP
If it fails (and/or exits with non-zero error code), please paste the \fIcomplete, unedited\fR output of the test tool into a bug report.  More information about reporting bugs can be found on the http://libguestfs.org/ website.

.SH "TRYING OUT A DIFFERENT VERSION OF QEMU"
.IX Header "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 \fI\-\-qemudir\fR option to point to the qemu source directory.
.PP
If you have downloaded a qemu binary from somewhere, use the \fI\-\-qemu\fR option to point to the binary.
.PP
Note when using these options, you can ignore the business of qemu wrapper scripts (\*(L"\s-1QEMU WRAPPERS\*(R"\s0 in \fBguestfs\fR\|(3)), since libguestfs-test-tool writes a wrapper script for you if one is needed.
.SH "TRYING OUT A DIFFERENT KERNEL"
.IX Header "TRYING OUT A DIFFERENT KERNEL"
You can tell supermin to try a different kernel.  You do this by setting the environment variables \f(CW\*(C`SUPERMIN_KERNEL\*(C'\fR, \f(CW\*(C`SUPERMIN_KERNEL_VERSION\*(C'\fR and/or \f(CW\*(C`SUPERMIN_MODULES\*(C'\fR.
.PP
Refer to \*(L"\s-1ENVIRONMENT VARIABLES\*(R"\s0 in \fBsupermin\fR\|(1) for further information.
.SH "TRYING OUT A DIFFERENT VERSION OF LIBVIRT"
.IX Header "TRYING OUT A DIFFERENT VERSION OF LIBVIRT"
To find out which backend is the default in your libguestfs package, do:
.PP
.Vb 2
\& unset LIBGUESTFS_BACKEND
\& guestfish get\-backend
.Ve
.PP
If you are using the libvirt backend, then you can try out a different (eg. upstream) version of libvirt by running these commands (\fInot\fR as root):
.PP
.Vb 2
\& killall libvirtd lt\-libvirtd
\& ~/path/to/libvirt/run libguestfs\-test\-tool
.Ve
.PP
The first command kills any session \f(CW\*(C`libvirtd\*(C'\fR process(es) that may be running on the machine.  The second command uses libvirt’s \f(CW\*(C`run\*(C'\fR script (in the top-level libvirt build directory) to set some environment variables so that the alternate version of libvirt is used to run the program.
.SH "TRYING OUT WITH / WITHOUT LIBVIRT"
.IX Header "TRYING OUT WITH / WITHOUT LIBVIRT"
To find out which backend is the default in your libguestfs package, do:
.PP
.Vb 2
\& unset LIBGUESTFS_BACKEND
\& guestfish get\-backend
.Ve
.PP
If you are using the libvirt backend, you can try without (ie. libguestfs directly launching qemu) by doing:
.PP
.Vb 1
\& export LIBGUESTFS_BACKEND=direct
.Ve
.PP
Or if you are using the default (direct) backend, then you can try libvirt:
.PP
.Vb 1
\& export LIBGUESTFS_BACKEND=libvirt
.Ve
.PP
or with libvirt and a specific libvirt \s-1URI\s0:
.PP
.Vb 1
\& export LIBGUESTFS_BACKEND=libvirt:qemu:///session
.Ve
.SH "TRYING OUT DIFFERENT SELINUX SETTINGS"
.IX Header "TRYING OUT DIFFERENT SELINUX SETTINGS"
To find out which backend is the default in your libguestfs package, do:
.PP
.Vb 2
\& unset LIBGUESTFS_BACKEND
\& guestfish get\-backend
.Ve
.PP
To find out if SELinux is being used, do:
.PP
.Vb 1
\& getenforce
.Ve
.PP
If you are using libvirt, SELinux and sVirt, then you can try to see if changing SELinux to \*(L"permissive\*(R" mode makes any difference.  Use this command as root:
.PP
.Vb 1
\& setenforce Permissive
.Ve
.PP
If this makes a difference, look in the audit logs for recent failures (\*(L"AVCs\*(R"):
.PP
.Vb 1
\& ausearch \-m avc \-ts recent
.Ve
.PP
You can convert AVCs into suggested SELinux policy rules using tools like \fBaudit2allow\fR\|(1).  For more information, see the \*(L"Security Enhanced Linux User Guide\*(R".
.PP
To reenable SELinux and sVirt, do:
.PP
.Vb 1
\& setenforce Enforcing
.Ve
