virtualbox how to not save changes in hd automatically

[patrykmoura]

Guys,
first of all, id like to thank this awesome softer!

But ive got a doubt... i used to create vms via Virtual PC, and id like to know if there´s an option on VIrtualBox, that lemme decide if I wanna save changes in the hdd or not?

THanks

Cya!

What do you mean by "save changes in the hdd"? I have to admit I don't understand what you are refering to.
Can you explain what you were able to do in Virtual PC that you want to reproduce here?

[patrykmoura]

oh yeah, sorry...

like, im a developer, and im doin several tests with my aplication, in diff OS´...
I like to, for example, install my app in the Virtual Box VM, but, when I close my session, i dont wanna the changes to be saved automatically, so i can install my app again and test all over again, whenever i want...

virtual pc does that, but it doesnt support windows 8... funny, cuz it s a microsoft product that doesnt support its own product! I know i know they have discontinued the VIrtual pc... but, still funny heheh

Set the guests drive to immutable.

See http://www.virtualbox.org/manual/ch05.h ... magewrites

Edit:  i cant see this option in settings->storage or in anywhere =/ Im using VBox 4.2.6 r8 for windows... And im running windows 8, in my station and on VM. tks

Use your VirtualBox main manager. Click file then virtual Media manager. Under the HDD find your guest VDI and the click modify. There you will find the setting you are looking for.

Note: guest needs to be shut down (not saved state) and I would think a backup would be in order.

You can also do this with VBoxManage and this is explained in your VirtualBox users manual.

AWESOME!!!

Now will I be ask if I wanna to save changes after I shutdown the machine, right?

That´s AWESOME!!!

Thanks!!!

No it won't ask you, it will simply throw away any changes made since you turned the disk to immutable.

[patrykmoura]

oh, and how can I do to save the changes?

[Perryg]

Switch back to standard. You can not save any changes until you switch back, so it is a one off until you reboot.

[patrykmoura]

oh... ok...
just one more question, cant we have both?

thanks for ur answers man!

[Perryg]

Nope.

You can take a {{cringe}} snap shot but that just sets you up for a failure should you have problems.

[patrykmoura]

Ok, just the "immutable" answer, for me was great!

thanks a lot my friend!!!

Topic can be closed!

You guys ROCK!
