Can't access to internet with my virtual machine

Question

In order to speed things up in a scientific computing software written in Python, I want to offload the construction and saving of intermediate figures to subprocesses using a multiprocessing.Pool().

The implementation is straightforward.

Most of the time it works fine but sometimes the subprocesses go into a deadlock and my program freezes.

I am running python on a UNIX machine.

Solution

1. In the main menu of VMWare go to Edit -> Virtual Network Editor. In the listbox choose an entry which has Bridged type (or create a new one). Below in VMnet Information the Bridged option should be selected for that entry. Make sure that in "Bridged to" combobox the correct adapter is selected (should be your physical adapter which is used by the host).

2. Now go to the Network adapter settings of your specific guest (VM -> Settings -> Network Adapter). In Network connection select "Custom: Specific virtual network option". Then in the combobox select VMnet# you previously set up in Virtual Network Editor.

3. Reboot you guest OS, see if that helps.

Does your physical machine have multiple interfaces? If so go in to the virtual network editor and verify that your bridge interface is set to use the correct physical interface.

Are you behind a firewall? Once I couldn't access the internet on a virtual machine, and eventually figured out it was a firewall.
