[PATCH libguestfs] maint: remove a subsumed syntax-check rule
by Jim Meyering
Hi Rich,
I noticed that libguestfs's cfg.mk had an old (and relatively
inefficient) version of the rule that checks for empty lines at EOF.
The one in maint.mk is much more efficient:

Subject: [PATCH libguestfs] maint: remove a subsumed syntax-check rule
* cfg.mk (sc_prohibit_trailing_blank_lines): Remove rule. It is now
subsumed by the much more efficient sc_prohibit_empty_lines_at_EOF
rule in gnulib's maint.mk.

NOTE: In libguestfs 1.19.41, the libvirt backend will have sVirt enabled by default
by Richard W.M. Jones
[If you're using the upstream libguestfs with default settings, then
this does NOT affect you. libvirt isn't required by libguestfs.]
>From libguestfs 1.19.41, if you have selected the alternate libvirt
method to launch the appliance, ie, if you have done:
./configure --with-default-attach-method=libvirt
then sVirt is enabled by default.
This is for enhanced security: if a malicious disk image manages to
corrupt the appliance *and* take over qemu, then SELinux provides
additional confinement of the qemu process, ensuring it cannot read or
write arbitrary files or other resources in the host. From Fedora 18,
this will be the default.
However sVirt won't work currently unless you patch libvirt and add
some SELinux policy. The details are in these two bugs:
https://bugzilla.redhat.com/show_bug.cgi?id=853393
https://bugzilla.redhat.com/show_bug.cgi?id=857453
I hope to get these fixes upstream soon.
Furthermore if you want to run 'make check' with libvirt + sVirt +
SELinux=Enforcing, then you'll need to label the 'tmp' directory in
the libguestfs sources:
cd /path/to/libguestfs
chcon --reference=/tmp tmp

ANNOUNCE: RHEL 6.4 preview packages available
by Richard W.M. Jones
As some may remember, in the run-up to RHEL 6.3 I made a yum
repository available of libguestfs and other packages. It's time for
the same thing for RHEL 6.4.
These packages should work on RHEL 6.3, CentOS 6.3 and other RHEL 6
derivatives (although I've only tried them on RHEL 6.3). A source RPM
is also supplied in case you want to try rebuilding the package.
To use the repo, run the following command as root:
cat >/etc/yum.repos.d/libguestfs-RHEL-6.4-preview.repo <<EOF
[libguestfs-RHEL-6.4-preview]
name=libguestfs RHEL 6.4 preview - x86_64
baseurl=http://people.redhat.com/~rjones/libguestfs-RHEL-6.4-preview/
enabled=1
gpgcheck=0
EOF
Then:
yum install '*guestf*'
Running 'libguestfs-test-tool' after this is a good way to test if
things are generally working or not. If you want to try a more
thorough set of tests, then see:
http://libguestfs.org/guestfs-testing.1.html
To go back to the supported packages, uninstall libguestfs, remove the
file /etc/yum.repos.d/libguestfs-RHEL-6.4-preview.repo and install
libguestfs from the usual place.
If you find bugs, please let me know, or file them in Bugzilla.
For a list of known bugs in libguestfs on RHEL 6, see:
https://bugzilla.redhat.com/buglist.cgi?component=libguestfs&product=Red%...

virt-rescue --ro option has no effect
by Olaf Hering
Should 'virt-rescue -a some.img --ro' tell qemu/kvm that some.img is
supposed to be read-only in the guest? I have not looked at the code
yet, perhaps --ro has a meaning only when attaching to a live guest.
I was expecting that all write access to some.img is denied in the
rescue shell.

guestfish(1) references non-existant tar_out/tar_in option
by Olaf Hering
While creating my first guestfish script I noticed an inconsistency in
the guestfish(1) man page. The option tgz-out references "tar_out",
which does not exist, instead its called "tar-out". The same is true for
tgz-in/tar_in. After a quick grep in the code its not clear to me how to
resolve this issue.

guestfsd process dead while quitting guestfish
by Richard Huang
I've compiled guestfsd and run it on CentOS 6.3. It worked well, but when I
quit guestfish, the guestfsd process in guest is always dead itself
automatically. Is this a bug? or did I miss something?
thanks.

I'm unclear exactly what the question is. You can compile guestfsd
(just the daemon) this way:
./configure \
--enable-daemon \
--disable-appliance \
--disable-fuse \
--disable-perl \
--disable-python \
--disable-ruby \
--disable-haskell \
--disable-php \
--disable-erlang \
--disable-gobject
make
$ ls -l daemon/guestfsd
-rwxrwxr-x. 1 rjones rjones 2073914 Sep 12 09:57 daemon/guestfsd
You still have to run that command on each distro/version that you
want to build a daemon for, assuming that's what you're trying to do.
Try:
./configure --help | grep -E -- '--(dis|en)able'
to get a list of things that can be enabled or disabled. There is no
way currently to disable building the library, tools and language
bindings as a whole, although arguably we should add that.

java.lang.UnsatisfiedLinkError
by 周涛
hi jones!
i run a java testcase in my new environment(V1.19.35 that was installed by "make install"),
"System.loadLibrary ("guestfs_jni")" leads to :
Exception in thread "main" java.lang.UnsatisfiedLinkError: no libguestfs_jni in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1860)
at java.lang.Runtime.loadLibrary0(Runtime.java:845)
at java.lang.System.loadLibrary(System.java:1084)
but "find /usr/local/lib -name '*guestfs_jni*' " returns:
/usr/local/lib/libguestfs_jni.so.1.19.35
/usr/local/lib/libguestfs_jni.so
/usr/local/lib/libguestfs_jni.la
/usr/local/lib/libguestfs_jni.so.1
and i tried to add "/usr/local/lib/" into LD_LIBRARY_PATH, but it had no effect.
could you tell me the reason?
Thanks!
