Mount an VHD on Mac OS X
- by janm
Is it possible (how) to mount an VHD file created by Windows 7 in OS X?
I found some information about how to do this on linux. There is a fuse fs "vdfuse" which uses virtualbox libs to mount filesystems supported by virtualbox. However I was unable to compile the package on osx because nearly all headers are missing and I doubt that it would work anyway...
EDIT #2: Okay I got my hands dirty and finally compiled vdfuse (http://forums.virtualbox.org/viewtopic.php?f=26&t=33355&start=0) on osx. As a starting point I used macfuse (http://code.google.com/p/macfuse/) and looked at the example file systems.
This led me to the following build script
infile=vdfuse.c
outfile=vdfuse
incdir="your/path/to/vbox/headers"
INSTALL_DIR="/Applications/VirtualBox.app/Contents/MacOS"
CFLAGS="-pipe"
gcc -arch i386 "${infile}" \
"${INSTALL_DIR}"/VBoxDD.dylib \
"${INSTALL_DIR}"/VBoxDDU.dylib \
"${INSTALL_DIR}"/VBoxVMM.dylib \
"${INSTALL_DIR}"/VBoxRT.dylib \
"${INSTALL_DIR}"/VBoxDD2.dylib \
"${INSTALL_DIR}"/VBoxREM.dylib \
-o "${outfile}" \
-I"${incdir}" -I"/usr/local/include/fuse" \
-Wl,-rpath,"${INSTALL_DIR}" \
-lfuse_ino64 \
-Wall ${CFLAGS}
You actually don't need to compile VirtualBox on your machine, just install a recent version of VirtualBox.
So now I can partially mount vhds. The separate partitions appear as block files Partition1, Partition2, ... on my mount point.
However Mac OS X does not include a loopback file system and macfuse's loopback fs does not work with block files, so we need a loopback fs to mount the blockfiles as actual partitions.
