It will take a few minutes for VirtualBox to "digest" the file. The software will read, unpack the input file and place the actual image (along with additional support files) some where on your file system. The actual location can be changes through one of the configuration option of the VirtualBox application. When the process is done then you should see the VM the GUI. HEre Here is an example:
Note that the initial state of the machine will be "Powered Off".
Testing and using the installed machine
Accounts, passwords
There is an important thing you need Accounts, passwordsto know about the security of your machine. The machine comes with two predefined accounts:
- root
- pcds
Both accounts have the same default password: LCLS2014 Please, change the one as soon as you start the image and log into the system! Protecting your system is solely your own responsibility. The passwords can be changed by logging as pcds and then switching to the superuser mode:
| Code Block |
|---|
% sudio -i
.. |
You should use the first one to manage your system (add/remove accounts, change passwords, configure the network, mount dists, etc.). The second account is used to install the LCLS releases. In general we do NOT recommend using that pcds account for your software development. It's set up
Starting/stopping
By default, after you start the machine, the network connection will not be enable on the VM. You shall locate the following sign on the title bar on the top right corner of the machine's GUI:
Which software is installed
Basically, we've tried to replicate the usual analysis environment, including the names of releases, a location of the release, the environment initialization commands (sit_setup), etc. And each VM image comes with at least one version of the full analysis release. There are some important exceptions though. In particular:
- you won't be able to see your NFS home directory even if you will add your own account to the system using your sudo privilege
- all accounts found on the machine have nothing to do with LCLS accounts

Final notes
- The default configuration of the virtual machine won't allow external login into the machine (one can'e do 'ssh' into the system). However, it's possible to give you machine a unique IP address to allow the logins. Instructions can be found in the VirtualBox documentation. And make sure you change the default passwords of both root and pcds accounts in your virtual image.
- Please, read the documentation on VirtualBox
