[ubuntu] VMware server 2 vsock warning

[remy06]

Hi,

Wondering if anyone encountered this vsock warning when installing vmware server 2 on intrepid.

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]

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.

it says i got to make sure gcc,binutils,make and kernel sources for my running kernel are installed.Any advice on how to fix it?

I get the same error when I am trying to compile vmtools with Ubuntu 8.10. I once found another thread on this virtualization forum but no one replies and the "advice" people give is incorrect, just plain wrong, or they say "just use Ubuntu 8.04." Well, thanks for that lame advice, but I am asking about Ubunutu 8.10 not 8.04. Basically it seems if you want to use VMWare and Ubuntu 8.10 it is not possible to install/compile the vmtools. Too bad, wish more people could help on this or offer suggestions that "work!"

I experienced the exact same error with "2.6.27-7-generic #1 SMP ... x86_64 GNU/Linux" and vmware-server 2.0.0-116503.x86_64

Was installed in Hardy (working) and upgraded yesterday to Intrepid. Trying to solve this since one day. Tried http://kramfs.com/2008/07/13/vmware-...e-vsock-module and http://www.insecure.ws/2008/10/20/vm...nd-kernel-2627 workarounds without success.
Currently downloading vmware-server 2.0.0-122956.x86_64 to see if this chnage anything.

[remy06]

i've tried vmware server 2 build 122956 x86 on intrepid following some of the links also but unsuccessful.Seems like there is still no solution for intrepid but am sure people are working it out so we may have to wait patiently.

I am having same issue after upgrading to intrepid kubuntu. This will probably be a major issue for anyone relying on vmware server 2 for more than just hobby work.

There is a patch but apparently its only for 1.x http://ubuntu-tutorials.com/2008/11/...627-7-generic/

I have vmware server 2 working on 2 Intrepid installations, a desktop and a server.

When I upgraded these two machines to Intrepid I was using vmware server 1.06. I had the vsock error on one machine when re-compiling the drivers but not the other. I used the patch someone else mentioned to get that one working.

In one install I had difficulty with the header files. I think the Intrepid upgrade failed to get the right ones. This would be worth checking - perhaps uninstall and re-install them?

In both cases I had a warning about the version of gcc (I think) being used but the final product worked fine.

I have also heard of people having success with vmware serve 2 and the patch (even though it's supposedly only for 1.xx):

This is because vsock depends on symbols from vmci module; the information is missing when vsock is built. I got vsock to build like this. (You need to have already installed vmware tools.)

$ cd /tmp
$ tar xf /usr/lib/vmware-tools/modules/source/vmci.tar
$ tar xf /usr/lib/vmware-tools/modules/source/vsock.tar
$ cd vmci-only
$ make
$ cp Module.symvers ../vsock-only
$ cd ../vsock-only
$ make

Copy /tmp/vsock.o to the appropriate location in /lib/modules, rerun 'depmod -a' etc.

You also need to change

answer VSOCK_CONFED no

to

answer VSOCK_CONFED yes

in /etc/vmware-tools/locations so that /etc/init.d/vmware-tools will load vsock on startup.

[thierrybo]

? But vmware-tools is build on guest machines, here the error occurs within host?

[dev13]

Oops, I misread the original message. I got a similar error trying to install vmware tools in a guest, and the above was how I solved that.

It does look like the cause for the error in the host is the same though. Does vmci get compiled for the host also? Can you get the Module.symvers file from it?

Yup, you can get it in the host/server version of vmware also.

I've patched the vmware-config.pl script with attached patch and with that I solved this issue. Thanks for pointing me at the right direction how to solve this.

This patch is for the most recent 2.0.0 version of VMWare: 122956
