Is there a way I can make my virtual drive image read only so no matter what I change, when I restart it it will be the same? I've tried making the file read only but it doesn't seem to work.

VBoxManage modifyhd <uuid>|<filename> --type immutable

From the manual: chapter 5.3
2. By contrast, immutable images only remember write accesses temporarily while
the virtual machine is running; all changes are lost when the virtual machine is
closed.

what is the erroer about using vbox manage modifyhd immutable?

fail to create object
code e no interface
vbox com server not running

type vboxmanage modifyhd c:\virtualbox\data\pro\pro.vdi --immutable

but have the error

Your command
vboxmanage modifyhd c:\virtualbox\data\pro\pro.vdi --immutable
Should be
VBoxManage modifyhd c:\virtualbox\data\pro\pro.vdi type --immutable

Thanks Does vbox allow putting the differencing drive on another folder

Which command would tell vbox the differencing drive on another folder?

The command you suggested have the same error messages

VBoxManage modifyhd c:\virtualbox\data\pro\pro.vdi type --immutable

@vuser01,

What is your host and what is the absolute path to the file?
If this is openSUSE as your profile says then you do not have a C drive.

Using xp and the virtualbox is a portable one and the pro.vdi is store on the folder of the portable vbox on pro folder

We don't support portable virtualbox they do. Seek support from http://www.vbox.me/
