similar to: Nasty little bug in guestmount found and fixed

The host is running Ubuntu 12.04 LTS and has the libguestfs package installed -- which, if I'm not mistaken, provides libguestfs-xfs: https://launchpad.net/ubuntu/+source/libguestfs Andre Goree ________________________________________ From: Richard W.M.

1/8 generator: Rearrange argt logically (RHBZ#642934,CVE-2010-3851). 2/8 generator: Optional arguments, add-drive-opts (RHBZ#642934,CVE-2010-3851). These two previously posted. 3/8 fish: Specify format of disks (RHBZ#642934,CVE-2010-3851). Updates to guestfish to add the --format option and to make -d copy the format from libvirt. 4/8 fuse: Specify format of disks (RHBZ#642934,CVE-2010-3851).

You can email libguestfs@redhat.com (no need to subscribe). The instructions for compiling

In 1.11.1 / git, I have made some changes to the way that you run guestfish, guestmount and the virt tools from the build directory without installing. Firstly you can't just run ./fish/guestfish or ./fuse/guestmount any more and have those programs magically set LIBGUESTFS_PATH. The automagic code was always error-prone and I have removed it. Secondly, all of the run-*-local scripts have

The architecture of

in fact, it was vhd and not hvd. if I understand correctly, guestmount uses qemu to allow the host to access the contents of the virtual machine disk : it makes it live to access its disk ? thank you for answering. 2018-06-28 16:30 GMT+02:00 Richard W.M.

This series of patches aim to make adding disks from libvirt domains easy through the core API. These two new APIs allow you to add the disks from a libvirt domain. The higher level add-domain API takes the name of the libvirt domain as a string and connects to libvirt itself. The lower level add-libvirt-dom API relies on the program to connect to libvirt and pass the virDomainPtr into the API

http://libguestfs.org/download/binaries/appliance/ This could be interesting for people trying to compile libguestfs on platforms which don't yet support febootstrap. I suspect it may also be useful for Debian. I'm not suggesting that Debian uses a binary appliance, but instead of having update-guestfs-appliance build a supermin appliance, it could build a fixed appliance (in two steps,
