Virtual drive Read Only

[wijs]

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.

vbox com server not running

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

but have the error

[Perryg]

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?

[vuser01]

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/
