Unable to make a vsock module

[paragkalra]

Hi Friends,

I have installed VMware Server 2.0 on Ubuntu 8.10 (HOST). Today I upgraded the kernel to include the modules for the webcam.

As a result of which after the upgradeVMware server failed to start and I had to rerun "/usr/bin/vmware-config.pl". The reconfiguration process failed to build the vsock module. Here is the complete set of messages:

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.

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.

I have following questions.

1. What all components of VMware won't because of it?

2. Has any one faced same kind of problem before, If yes were you able to resolve it?

3. I restarted one of my already created VM and it seem to work fine. What are the potential issues I might face with my already created VMs due to absence of vscok module.

There is a link to a solution in the Virtualization mega thread.

There is a reason it is a sticky

[paragkalra]

Thanks bodhi.zazen...the patched worked like a breeze...

[bodhi.zazen]

No problem, thank you for using the sticky.

But I can not take credit for the patch, it is a community effort, I am just trying to track and organize it all, make it easier to find and access.
