it shows only for mounting vdi files when linux is running

Re: HOWTO: Mount any VBox-compatible disk image on the host
Will this work for a dynamically expandable file system as well?

Re: HOWTO: Mount any VBox-compatible disk image on the host
My ubuntu.vdi won't boot because of grub error 17. So this thread is useless to a non-bootable linuxbox. I had made a backup, but it is a backup with the grub error. I'm trying to mount it so I can fix it. Need suggestions that don't include reinstalling an OS that I spent weeks working on. This whole problem started just trying to backup the ubuntu installation. Reinstalling a whole OS opens up a whole nother can of worms that could have been prevented if virtualbox had an easy to use backup sysyem compatible with virtualbox.

boot your virtual machine with your ubuntu install CD .iso, select live CD option (not install)
when live CD up and running get a terminal, be root, mount your ubuntu .vdi filesystem (probably /dev/sda1) somewhere and chroot somewhere
then running update-grub could fix your problem

Re: HOWTO: Mount any VBox-compatible disk image on the host
Hello, I'm unable to compile vdfuse-v70.c under Ubuntu 10.04 LTS (lucid). It seems like there's no package shipping VBoxHDD.h or VBoxHDD-new.h:
root@most:~# apt-file search VBoxHDD
root@most:~# apt-file search VBoxHDD.h
root@most:~# apt-file search VBoxHDD-new.h
root@most:~#

Re: HOWTO: Mount any VBox-compatible disk image on the host
Awesome! I just used your script to complete the preparation of my customized OS disk for imaging on over to its real home -- a 2GB CF-II card w/ adapter for IDE use. Computating offsets, while good practice, becomes awfully annoying when you are just trying to get a project quickly under wraps ... thank you for providing this script & saving me time!
Virtualbox, whereas it was a tid bit slow due to my aging hardware, greatly simplified the testing process for bootstrapping a couple disk array nodes across RAID10 and glusterfs. Eight virtual disk drives over software RAID, including LVM volumes and all via virtualization on a close-to identical physical hardware platform. Gotta love it...!

Re: HOWTO: Mount any VBox-compatible disk image on the host
What's the chance that this procedure will allow me to somehow fix a bad snapshot? The CloneVDI tool tells me that one of my earliest snapshots has a bad block map. If the snap were a normal disk, I'd try to fsck it somehow, but being a snap, it's not the same
My users have lost 6 months of emails from this, so any help fixing this snap (so that CloneVDI can fix/rebuild properly) would be greatly appreciated!

Re: Discuss: Mount any VBox-compatible disk image on the host
Hey .. In the tutorial I could execute all command but the last mount one .. What is the exact equivalent for "./vdfuse-v<version> -f image.vdi /mnt/vdi" ?
I have a vmdk file.
I have a vmdk file.

Re: Discuss: Mount any VBox-compatible disk image on the host
So another version of "boosted" recipe I posted on my wiki 2.5 years ago is floating on the net? This time with losetup (TBH don't remember all previous incarnations, so cannot tell whether losetup was used before).
And again, w/o any origin information pointing to http://wiki.przemoc.net/tips/linux#moun ... size_image. Yet information about alleged author and license takes 1/3 of the script.
Just saying.

Re: Discuss: Mount any VBox-compatible disk image on the host
Anyone know if it's possible to copy the vdfuse program from an OSE installation to a PUEL one, and use it to mount VHDs?
I'm assuming the libs (not many from a look at what readelf dumps out) it needs are present in both versions.
I'm actually trying it now, but so far it doesn't want to run ("./vdfuse: 1: Syntax error: end of file unexpected"), so I'm wondering if there's some (probably completely obvious) reason why this is a no-go from the outset.
