Mounting a VirtualBox hard disk image file (.vdi) in Linux

Searching the web, I found this post about mounting a vdi file in Linux.

• On Fedora 15, you need to install these packages:


# yum install nbd qemu-common


• To mount a partition on a hard disk image file:


# modprobe nbd
# qemu-nbd -c /dev/nbd0 "file.vdi"
# kpartx -a /dev/nbd0 # creates mapped devices in /dev/mapper/
# mount /dev/mapper/nbd0p1 /some/folder # mounts first partition of the image.


• To unmount:


# umount /some/folder
# kpartx -d /dev/nbd0
# qemu-nbd -d /dev/nbd0
