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 ? -- Evaggelos Balaskas - Unix System Engineer http://gr.linkedin.com/in/evaggelosbalaskas

Release notes appendix for libguestfs 1.20 on Fedora 18
by Richard W.M. Jones 17 Dec '12

17 Dec '12

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. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-df lists disk usage of guests without needing to install any software inside the virtual machine. Supports Linux and Windows. http://et.redhat.com/~rjones/virt-df/

inspect_os error with Win7 image
by Skippy VonDrake 14 Dec '12

14 Dec '12

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 Suggestions?

[PATCH 1/2] daemon: NFC Use symbolic names in commandrvf

Improve readability of commandrvf() by replacing bare int values for file descriptors with their symbolic names STD{IN,OUT,ERR}_FILENO.

febootstrap - Arch User Repository

14 Dec '12

Arch User Repository - https://aur.archlinux.org/ have changed the package location I am not a developer (and i dont know ocaml) but i've tried to build a patch eg. old location: http://aur.archlinux.org/packages/hivex/hivex.tar.gz new location: https://aur.archlinux.org/packages/hi/hivex/hivex.tar.gz AUR has a lot Flagged out-of-date packages so it would be nice if febootstrap would have a parameter for adding a custom (local or not) repo. I'll try to help (with archlinux specs) and try as exercise to provide a patch - if you are going to consider adding support for declaring a custom repo. Any thoughts about that? -- Evaggelos Balaskas - Unix System Engineer http://gr.linkedin.com/in/evaggelosbalaskas

Lua improvements
by Hilko Bengen 13 Dec '12

13 Dec '12

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, -Hilko
