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. ",defect,closed,virtual disk,VirtualBox 6.1.32,fixed,vboximg-mount,,Linux,Linux
