<title>Opening the Encrypted VM</title>
<body>
<p>
When Oracle VM VirtualBox has just started up the encrypted VM cannot
be opened and it stays inaccessible. Also, the encrypted VM
stays inaccessible if it was just registered without a password
or the password is incorrect. The user needs to provide the
password using VirtualBox Manager or with the following
<userinput>VBoxManage</userinput> command:
</p>
<pre xml:space="preserve">VBoxManage encryptvm <varname>uuid</varname>|<varname>vmname</varname> addpassword --password <varname>filename</varname>|- --password-id <varname>ID</varname>
</pre>
<p>
To supply the encryption password point
<userinput>VBoxManage</userinput> to the file where the password is
stored or specify <codeph>-</codeph> to let
<userinput>VBoxManage</userinput> prompt for the password on the
command line.
</p>
<p>
If <varname>ID</varname> is the same as the password
identifier supplied when encrypting the VM it updates the
accessibility state.
</p>
<p>
To remove the entered password from the VM memory, use
<userinput>VBoxManage</userinput> as follows:
</p>
<pre xml:space="preserve">VBoxManage encryptvm <varname>uuid</varname>|<varname>vmname</varname> removepassword <varname>ID</varname>
</pre>
<p>
If <varname>ID</varname> is the same as the password
identifier supplied when encrypting the VM it updates the
accessibility state.
</p>
<note>
<p>
If a machine becomes inaccessible all passwords are purged.
You have to add required passwords again, using the
<userinput>VBoxManage encryptvm
<varname>vmname</varname> addpassword</userinput>
command. See <xref href="#vmencryption-addpassword"/>.
