Searching the web, I found this post about mounting a vdi file in Linux.
- On Fedora 15, you need to install these packages:
- To mount a partition on a hard disk image file:
- To unmount:
# yum install nbd qemu-common
# 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.
# umount /some/folder
# kpartx -d /dev/nbd0
# qemu-nbd -d /dev/nbd0
Not to Forget 
Hi!
The device /dev/nbd0p1 is not created automatically. So you should use
# kpartx /dev/nbd0
and
#kpartx -d /dev/nbd0
on the umount side.
I’m sure, at the time of writing this, I never used `kpartx‘. Actually I never heard of it before you mentioning it!
But now, after I tried to mount a vdi file, as you said it, I had to do a “
# kpartx -a /dev/nbd0” to map the partitions. And the mapped devices are “/dev/mapper/nbd0p?“.Thank you for your consideration and correction.
I will update the post accordingly!
Graze infinite!! Utilissima! 🙂
Thanks very much!! Usefull!! 🙂
