Currently guestfish has mount-vfs, and the libguestfs API has guestfs_mount_vfs(), but guestmount doesn't allow the user to specify a filesystem. This patch extends the --mount argument, so you can force an ext2 partition to mount as ext4: guestmount -a mydisk.img -m /dev/vda:/:defaults:ext4 mountpoint You could also use it to choose between ntfs and ntfs-3g, or between hfsplus and the

In libguestfs we have a few tests that require root privileges and they are skipped by default (normally you should not build or test as root), but you can do this to run them: sudo make check-root In nbdkit I wanted to check that the file plugin works with block devices (this is not tested), and the only way I can sensibly think to do this is using a loopback device and root.

Hi ,all : thanks for helping me ! I am using libguestfs-1.28.1 on ubuntu 12.04 to manage vm disk created by KVM. I downloaded libguestfs-1.28.1.tar.gz ,and then executed (1) ./autogen.sh (2) ./configure (3) make (4) make check .there is the error. /usr/Libvmi/libguestfs-1.28.1/run --test guest-aux/make-fedora-img.pl md_create: feature 'mdadm' is not available in this

...y supported through the API, making reading or editing the Windows Registry much more efficient. Several libguestfs APIs were reimplemented so they no longer have any limits on output. The reimplemented APIs are: guestfs_cat, guestfs_find, guestfs_read_file, guestfs_read_lines, guestfs_write, guestfs_write_append, guestfs_lstatlist, guestfs_lxattrlist, guestfs_readlinklist, guestfs_ls. virt tools guestfish touch 'win:c:\new_file' now works as expected. guestfish has a new --network option, which enables the user network in libguestfs. You can set G...
