CD/DVD change while running not working in 3.1.0

[costan]

Hello,

I just upgraded VirtualBox to 3.1.0, attracted by live migration.

I'm the process of installing the VirtualBox tools addons, but I can't switch CD/DVD contents anymore with CLI.

Former release syntax:

VBoxManage controlvm <VM name> dvdattach <name of image or UUID>

It worked like a charm since 3.1.0

Now that syntax is not reported anymore in the help, but it's still accepted if you try, BUT it doesn't work!

I've tried with the storageattach thing, but it works during VM poweron for changing the media, but it doesn't allow you to remove it.

Everything works correctly if you perform a (powered off machine) modifyvm to change the media at boot time.
Of course I think it's not acceptable to reboot the system just to switch the CDROM contents..


Hope it helps.

Ciao,
A.

You probably forgot to unmount the current media first:

Code: Select all

VBoxManage storageattach <vmname> --device <number> --medium emptydrive

You might need to change emtpydrive to none and use --forceunmount if it doesn't work. After that, you can attach it:

Code: Select all

VBoxManage storageattach <vmname> --device <number> --medium filename

You're perfectly right.

I used to put "none" instead of "emptydrive".

Sorry about that.

I suggest to put a note on the manual if feasible.



Thanks again
Andrea

Hello
Thanks for suggested solution.
But what about VBoxManage controlvm <name> dvdattach, will it work again?
