20896,Changes to vdi image using vboximg-mount are not persistent,jpt,,"Hi,

File {{{/new_vdi.vdi}}} created by the VBox Machines' Management Tool, attached to a machine running Linux Debian Bullseye 64bits and partitionned/formated with gparted.
That partition is then mounted and copying data (file ""from_vm.txt"") to it works fine, so power off machine and detach file from machine.

Then, using a terminal from the host, where /x and /y are two mountpoints for test :

1st run, writing file ""from_host.txt"" to vdi image :
{{{
vboximg-mount --rw -i /new_vdi.vdi -o allow_root /x/
mount /x/vol0 /y/
touch /y/from_host.txt
echo ""try from host"" > /y/from_host.txt 
sync
ls /y/ # --> from_host.txt  from_vm.txt  lost+found
cat /y/from_host.txt # --> ""try from host""
umount /y/
umount /x/
}}}
Everything is fine.

2nd run, reading from vdi image :
{{{
vboximg-mount --rw -i /new_vdi.vdi -o allow_root /x/
mount /x/vol0 /y/
ls /y/ # --> from_vm.txt  lost+found
umount /y/
umount /x/
}}}
Written file ""from_host.txt"" lost !

Same problem here https://www.reddit.com/r/virtualbox/comments/mogadt/vboximgmount_readwrite_persistence/ or there : https://forums.virtualbox.org/viewtopic.php?f=7&t=96967&p=515917, and no one provides a good working command line.

Thanks a lot in advance.
