Vmware-Tools and time synchronization: Difference between revisions

Revision as of 09:08, 2 March 2006

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:

Install Virtual Machine (e.g. SuSE 9.3 used here) with pcnet32 network module (default) including the kernel sources.
Run Yast Online Update you. This updates the packets + kernel + kernel sources.
Reboot.
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
```
.
Now we have to configure the kernel sources:

cd /usr/srs/linux make cloneconfig make prepare

Now we can successfully run
```
/usr/bin/vmware-config-tools.pl
```
and follow the instructions.
Run vmware-toolbox and check button .
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

Shutdown the VM and to use vmxnet module instead of pcnet32
