I have a Windows host that runs guest Ubuntu VM via vmplayer. That virtual machine will be cloned, distributed among several people (running Windows hosts) and used for conducting a programming workshop. I am trying - and so far failing - to setup networking to satisfy the following requirements:

  1. The guest has to have access to the internet

  2. All the clones should have the same hostname (let's say Workshop to be concrete)

  3. The host system must be able to access its respective guest via that name (e.g. ping Workshop would ping the guest that is running on that host and not any other clone)

What I've tried so far:

  • "Installed" a NAT network adapter for the guest

  • Tried to connect the guest via DHCP, in /etc/network/interfaces:

    auto eth0
    iface eth0 inet dhcp
    hostname Workshop

That works as far as connecting to the internet is concerned. However, I am unable to connect to the guest from the host at all. (E.g. ping Workshop does not work; if I use the address returned by ifconfig it does not work either from the host).

  • I then tried assigning a static address to the guest:

    auto eth0
    iface eth0 inet static

( is the address assigned statically to the host by VMWare Network VMNet8 Adapter - that's the NAT adapter above). Now, I can ping and telnet to it from the host. I can also ping and telnet from the guest to (the host), but that's about it - there is no connection to the wider network. (I also can't access the guest via its hostname, but that's not crucial here since if push comes to shove I can use its address directly - as long as it is the same for everybody - and not the name).

Now, I think I can use the bridged network connection option with DHCP and that will give me what I need in case of one VM (I did not try it in this case, but I remember doing it previously). However, in case of several VM's with the same hostname and their hosts connected to the same network that will be problematic, won't it?

Your solutions and other advice will be much appreciated.

First of all, yes, you won't be able to use a bridged network connection because all of the guests will have the same hostname, so you'll have to go with NAT.

You got part of the configuration right, however, your problem should be in the default gateway that you assigned to the guest. The default gateway, when using NAT, is not the IP of the host, it's the IP of a "virtual switch" that's connected to the NAT network. (The host VMnet8 adapter is merely another device connected to the network, to allow the host to communicate with the VM.) This virtual switch we're talking about gets the .2 IP in the subnet. So in your case, your /etc/network/interfaces should read:

auto eth0
iface eth0 inet static

This should grant your guest VM access to the internet (through, and also communicate with your host ( So try it out and let me know if it works.

If it doesn't work (highly unlikely), then you need to find out what the IP of the virtual switch is. What you can do is let the VM get an IP through DHCP (i.e. change it to iface eth0 inet dhcp like you had it before), and then do route -n. This should show you the default gateway it's using. Use that IP in your static configuration.

To be able to ping the guest VM using its hostname Workshop, here's what you can do. You need to add an entry in the hosts file in Windows, which is located in C:WindowsSystem32driversetchosts. Edit that file to include the following line in the end:

To edit that file under Windows however, you need to open it as an administrator in Notepad or Wordpad...and sometimes it doesn't even let you save it, so you'll need to take a copy of the file somewhere, edit it, remove the .txt extension if it got one, and go back and replace the original one, and "confirm" it...oh how I love Linux. But anyways, here's the line you need to add:    Workshop

Once this is done, you should be able to ping Workshop successfully from your Windows host.

Though of course, to be able to deploy this in your workshop, you'll need to edit the hosts file in every single Windows host, unless you're also cloning the Windows machines.

Tip: since you're going to assign a static IP to your guest, make sure that the "NAT network" in VMplayer on all of your Windows hosts are using the subnet, because I think VMware randomly assigns a subnet to its virtual networks (VMnet1, 2, and so on), so VMnet8 might not be using the same subnet on another Windows host. If they're not, you'll need to manually give VMnet8 a subnet using the Virtual Network Editor in VMware.


Okay. After the comments, here's what you need to do:

  1. Configure your (Windows) host machine to "obtain IP address automatically" on the VMnet8 adapter. It should get the IP

  2. Configure your (Ubuntu) guest machine to a static IP in the range - Let's use Also, configure the default gateway and dns server to be So your /etc/network/interfaces should be:

    auto eth0
    iface eth0 inet static

  3. Test local connectivity by pinging and from the guest machine. You should also be able to ping from the host to the guest.

  4. Test internet connectivity in the guest machine by pinging google.com, or browsing the internet.

  5. Add the line Workshop to your hosts file in the Windows host machine.

  6. Test ping Workshop from the Windows host machine.

If you want to use IPs from an altogether different network/pool other than, you'll need to go to Edit > Virtual Network Editor in VMware, find VMnet8, and change its DHCP settings at the very bottom to whatever network you want, and change the static IPs accordingly (the default gateway will always be the second usable IP, x.x.x.2).
