read-write in LIBGUESTFS 1.20
by Evaggelos Balaskas
How can i open a virtual disk in read-write mode ?
# guestmount --rw -d winxp -m /dev/sda1 /media/
# rm -f /media/pagefile.sys
rm: cannot remove ‘/media/pagefile.sys’: Operation not permitted
# cd /media && touch file
touch: cannot touch ‘file’: Permission denied
# cd && fusermount -u /media
I've tried with guestfish also.
I have compiled libguestfs with this conf:
./configure \
PYTHON=/usr/bin/python2 \
--prefix=/usr --libdir=/usr/lib \
--mandir=/usr/share/man \
--sysconfdir=/etc \
--disable-probes \
--disable-gobject \
--enable-introspection=no \
--disable-lua \
--disable-erlang \
--disable-php \
--disable-haskell \
--disable-ruby \
--without-java \
--with-default-attach-method=libvirt
am i missing something ?

Release notes appendix for libguestfs 1.20 on Fedora 18
by Richard W.M. Jones
I'm just about to release libguestfs 1.20. This appendix covers
issues specific to Fedora 18.
Fedora 18 defaults to using the libvirt attach-method, meaning that
libvirt is used to create and manage the libguestfs appliance. There
are several benefits to this (see the full release notes). You can
switch back to the ordinary method (directly running qemu) at any time
by doing:
export LIBGUESTFS_ATTACH_METHOD=appliance
There is a bug in libvirt (or perhaps libnl, or somewhere else) which
causes libvirtd to segfault occasionally:
https://bugzilla.redhat.com/show_bug.cgi?id=875741
You will need selinux-policy >= 3.11.1-63.fc18 and
libvirt >= 0.10.2.1-3.fc18 in order to use SELinux in Enforcing mode
giving you the full benefit of sVirt protection. I have tested this
and it all works well for me, but please open bugs if you find any
problems.
Rich.

inspect_os error with Win7 image
by Skippy VonDrake
The error message:
hivex_close: do_hivex_close: you must call 'hivex-open' first to
initialize the hivex handle
This is the process flow:
g = guestfs_create ();
guestfs_add_drive_opts (g, diskFile,GUESTFS_ADD_DRIVE_OPTS_FORMAT,
"raw",-1);
guestfs_launch (g)
char **roots = guestfs_inspect_os (g);
guestfs_inspect_os returns NULL, guestfs_last_error(g) returns message above.
And guestfs_last_errno(g) returns 0.
However this same code works fine with a Server2008 image and an XP image.
I copied the verbose output to pastebin: http://pastebin.com/U9Jb6JwH

[PATCH 1/2] daemon: NFC Use symbolic names in commandrvf
by Matthew Booth
Improve readability of commandrvf() by replacing bare int values for
file descriptors with their symbolic names STD{IN,OUT,ERR}_FILENO.
Also add PIPE_READ and PIPE_WRITE for referencing relevant ends of a pipe.

Lua improvements
by Hilko Bengen
Here are a few patches I applied to get the Lua bindings to build
correctly with different versions of Lua.
I am not particularly happy with generating all the test scripts just
for the shebang line. Since it has been a while since I had to edit
autoconf/automake, this was the best I could come up with.
Cheers,
