Port forwarding should work in most cases, however to install a DICE Guest OS with PXE/DHCP and to use ports below 1024 you need to enable the Bridged networking option. For the example above this would mean adding the following lines to the physical host machines LCFG profile (you will need to contact support to do this).įor complex port-forwarding arrangements you may be better asking support to create a self-managed profile: see below.

If you require the service to be visible outside of inf.ed.ac.uk then the physical host will need filter rules added exactly as if the service was running natively on that host but based on the host port not the guest port (so =8080= for the example above).

Note that it is not possible to configure port forwarding while the Guest OS is running, completely shut down the Guest OS and exit the =VirtualBox= application first.įor more information on port forwarding please see the VirtualBox Manual page on the topic. $ VBoxManage modifyvm 'myfc10host' -natpf1 delete 'guesthttp'Īnd to check the current configuration use the VBoxManage showvminfo command. To remove a port forwarding configuration, use the following: You might also have to check that your Guest OS does not apply any network filtering by default that would prevent services being run in this way. With the configuration in place, all TCP connections to port 8080 on the physical host will now be forwarded to port 80 on the Guest OS. The Protocol can be either tcp or udp (these are case insensitive). The name guesthttp is an arbitrary tag chosen to identify this particular port forwarding configuration and can be anything you like. The number one in the argument -natfp1 refers to the first (and default) network card. Here 'myfc10host' is the name of the virtual machine as displayed in the VirtualBox interface. $ VBoxManage modifyvm 'myfc10host' -natpf1 'guesthttp,tcp,8080,80' For example, to set up an incoming NAT connection to an http server on the Guest OS would require the following: You can use any ports on the host greater than 1024 which are not already in use by a service. You will need to know which ports on the Guest OS the service uses and decide which ports to use on the physical host (often but not always you will want to use the same ports on the Guest OS and on the host). You can set up a service on the Guest OS and then set up the host to proxy incoming connections to that service using the command line tool VBoxManage. Both are described below.įor DICE guests see Bridged_Adapter comments, below. Bridged Adapter is also a possibility but you should try port forwarding first. In this case we recommend that you use Port Forwarding. The default virtual machine configuration uses NAT which should be fine for almost anything except if you want to run services on the Guest OS and have them accessable from other machines on the Informatics or University networks or from the internet in general. Note that you have to first mount the image file or CD to make it available to your virtual machine - use the CD menu within the !VirtualBox GUI to do this.Īlternatively you can use one of the pre-built base images (such as Fedora10) and a local differencing disk, see ] comments, below.

You can then install any Guest OS from an ISO image or physical CD (eg. Follow the GUI Wizard to create a new virtual host and virtual disk image on the physical disk (ideally in /disk/scratch rather than your home directory for obvious performance reasons). Login to your DICE machine as normal and start up a terminal and run the VirtualBox command. What's worse, they're off by default on all our standard desktop machines. These are crucial for best performance of host and guest their absence is implicated in some problems experienced on 745s. For performance reasons if you are going to make heavy use of a virtual machine on your desktop you should ask support to make sure that CPU Virtualisation Extensions (VT-X) are enabled in your machine's BIOS, if available (all 745s and newer).
