Linux

Hello I am trying to install VMWARE in Ubuntu 8.10 and I have two issues.

VMWARE server wants to compile modules to work with my kernel one them gives an error. What do I do:

None of the pre-built vsock modules for VMware Server is suitable for your
running kernel. Do you want this program to try to build the vsock module for
your system (you need to have a C compiler installed on your system)? [yes]

Extracting the sources of the vsock module.

Building the vsock module.

Using 2.6.x kernel build system.

There is probably a slight difference in the kernel configuration between the
set of C header files you specified and your running kernel. You may want to
rebuild a kernel based on that directory, or specify another directory.

The VM communication interface socket family is used in conjunction with the VM
communication interface to provide a new communication path among guests and
host. The rest of this software provided by VMware Server is designed to work
independently of this feature. If you wish to have the VSOCK feature you can
install the driver by running vmware-config.pl again after making sure that
gcc, binutils, make and the kernel sources for your running kernel are
installed on your machine. These packages are available on your distribution's
installation CD.
-----------------------

My second question:

During the install it asks me for the following:

Configuring a NAT network for vmnet8.

Please specify a name for this network. [NAT]

Do you want this program to probe for an unused private subnet? (yes/no/help)
[yes]

Probing for an unused private subnet (this can take some time)...

The subnet 192.168.31.0/255.255.255.0 appears to be unused.

The following NAT networks have been defined:

. vmnet8 is a NAT network on private subnet 192.168.31.0.

Do you wish to configure another NAT network? (yes/no) [no] no

Do you want to be able to use host-only networking in your virtual machines?
[yes]

WHat is a NAT Network, private subnet, and host only networking? SInce I am a newbie I just select the defaults but I figure I should ask....

This is from the VMWare server 1 documentation, but the same applies to version 2

http://pubs.vmware.com/server1/wwhel...tml/wwhelp.htm

If you set up NAT (network address translation), your VM can access the external network (presumably including the Internet) with your host machine (your physical machine) acting as a proxy using the network routes available on your host system. However, with this option you will not be able to access the VM from other machines except your host machine.

Host-only networking is an option if the VM doesn't need to access any outside network. Typically this is not desirable except if what you need is to set up an isolated VM environment for testing.

Please consider reading the relevant chapters in the documentation for further information.
