![]() If you are interested in full featured already implemented solutions, OpenStack seems interesting choice. ![]() Remote virtual machines - Step by step: creating a virtual machine on a headless server Related VirtualBox manual's chapter: Chapter 7. VBoxManage startvm - start with GUI for local debugging. ![]() rdesktop IP-ADDR:3389 or rdesktop-vrdp IP-ADDR:3389 - when you would like a GUI (even remotely) when you run in headless mode : VBoxHeadless -s |.VBoxManage list vms - list of available vms.Save VM state in order to restore afterwards.Emulate "shut-down button" or "sleep button" and prepare VM to react on it (to close gracefully).IF you want to turn off VM gracefully, you have two options, depending on your application: VBoxHeadless -s "$1" #run in headless mode in background VBoxManage showvminfo "$1" | grep State #display state to ensure VBoxManage snapshot "$1" restorecurrent #retore state VBoxManage controlvm "$1" poweroff #enforce turnoff I have a few of such services so I use following script: What you are interested in is headless-mode. When you will need to be fast with Linux you will feel the need of ssh-keygen and to Generate once SSH Keys to copy files on/from a remote machine without writing password anymore.I have similar application as you, with one difference: I need to restart system and recover from snapshot. I mean I suggest you to enable Drag & drop to be cosy with the Windows machines and the Shared folders or to be cosy with Linux. It's easy to overcame it: it's enough to give authorization to read/write/execute to a directory or to chose a different directory in which both users can read/write/execute. This is a restriction due to the hosting OS. When each of them run a virtual machine, for the hosting OS those virtual machine are two normal programs owned by Hastur and Meow and cannot see the private directory of the other user. Each virtual machine has its own operative system running on and acts as a physical machine.Įach virtual machine is an instance of a program owned by an user in the hosting operative system and should undergo the restrictions of the user in the hosting OS.Į.g Let we say that Hastur and Meow are users of the hosting machine, but they did not allow each other to see their directories (no read/write/execute authorization).You should remember that you are dialling with a little network of machines with different operative systems, and in particular: You may find interesting the article Sharing files between guest and host without VirtualBox shared folders with detailed step by step instructions. You can mount part of the file system of a virtual machine via NFS or SSHFS on the other, or you can share file and directory with Samba. You can install with sudo apt-get install openssh-server. Note: many Linux/Ubuntu distribution install sshd by default: you can see if it is running with pgrep sshd from a shell. Of course you need to have the authorization setted (via password or, better, via an automatic authentication method). You need an active server ( sshd) on the receiving machine and a client on the sending machine. you can get some info about SSH servers e.g. You can use usual method to copy files between 2 different computer with client-server application. If you use the same folder shared on more machines you can exchange files directly copying them in this folder. ![]() (Keep in mind that can arise some problems for date/time of the files when there are different clock settings on the different virtual machines). As you put a file in a shared folder from host OS or from guest OS, is immediately visible to the other. You have the possibility to set Shared Folders too. You can have common Shared Folders on both virtual machines and use one of the directory shared as buffer to copy. You can enable drag and drop too with the same method (Click on the machine, settings, general, advanced, drag and drop: set to bidirectional ) Then you paste from the host OS to the second guest OS. You copy from guest OS in the clipboard that is shared with the host OS. You can copy few (or more) lines with copy & paste mechanism.įor this you need to share clipboard between host OS and guest OS, installing Guest Addition on both the virtual machines (probably setting bidirectional and restarting them). The answer should be complex, I hope not too much complicate, but more you read down more it is complex:
