There are several reasons for installing Vmware Tools in the guest-OS:

  • Better network performance by using vmxnet module
  • May be better Virtual-disk speed because /etc/init.d/vmware-tools sets up hdparms.
  • Time synchronization hetween host & guest OS.

Installation:

  1. Install Virtual Machine (e.g. SuSE 9.3 used here) with pcnet32 network module (default) including the kernel sources.
  2. Run Yast Online Update you. This updates the packets + kernel + kernel sources.
  3. Reboot.
  4. Install the Vmware-Tools. We use the 
    dc:/pub/software/RPM/VMwareTools-5.5.1-19175.i386.rpm
    which compiles better with 2.6 kernals then the variant distributed with vmware-gsx-server.
    rpm -i VMwareTools-5.5.1-19175.i386.rpm
    .
  5. Now we have to configure the kernel sources: 

cd /usr/srs/linux
make cloneconfig
make prepare

  1. Now we can successfully run 
    /usr/bin/vmware-config-tools.pl
     and follow the instructions.
    2. 

  2. Run  vmware-toolbox  and check button Options->Time synchronization ....
    3. 

  3. Unfortunatly the guest OS gives timerevents with maximum 1000Hz, what is to slow fror the Linux-SMP-2.6 default kernel. See Therfore we have to add the kernel boot options: clock=pit noapic nolapic nosmp

  1. Shutdown the VM and configure the network to use vmxnet module instead of pcnet32 Screen2.png.
    2. 

  2. Poweron the VM and couse the right driver for eth0 (it should be named eth? because even /etc/init.d/vmware-tools has to find it) Example:

brn-suse093-1:~ # cat /etc/sysconfig/hardware/hwcfg-bus-pci-0000:00:11.0
MODULE='vmxnet'
MODULE_OPTIONS=''
STARTMODE='auto'

brn-suse093-1:~ # cat /etc/sysconfig/network/ifcfg-eth0
BOOTPROTO='dhcp'
MTU=''
NAME='VMWare VMware High-Speed Virtual NIC [vmxnet]'
REMOTE_IPADDR=''
STARTMODE='auto'
UNIQUE='7EWs.eUHVfjJn0H8'
USERCONTROL='no'
_nm_name='bus-pci-0000:00:11.0'
