If a filesystem has been mounted read-only chmod will not work since its a write operation too. This filesystem supports 64-bit storage limits columns up to 1 exabytes and you may store files up to 16 terabytes. All we need is a writable filesystem to union with the read-only layer. This is specified in fstab as errorsremount-ro and will occur when a FS access fails or an emergency read-only remount is requested via AltSysRqU. The computer is also very slow and freezing all the time.

If you want particular file systems on Linux to always be accessible in read-only mode you must specify it in the file system configuration file fstab. Hardware locks cannot be disabled by software. If you are editing something you are unable to save and have to execute fsck command and reset the computer. Look at the file attribute of the VMs VDI file in the Windows file manager.
