Suse Linux install vmware tools

Q. I’m using OpenSuse as Guest OS (VPS). Installing SUSE Linux as a VMware Workstation guest operating system was easy task. But how do I setup and install SUSE Linux as a VMware Guest? How do I install vmware tools to improve performance?

A. In order to install Vmware tools, you need to build kernel modules. Building kernel modules is easy provided that following packages are installed on the guest OpenSuse / Suse Linux (VPS):

=> kernel-source

=> binutils

=> make

=> gcc

=> gcc-c++

Install required software

Login to guest oses using SSH or Vmware server console. Use yast command (yast control center) to install required software:
# yast
Select Software > Software management > Add above packages > Accept and install the softwares
The Software Management tool in YaST text mode
(YaST text mode software installation)

If you are using a GUI, you should see screen as follows (YaST2 screen):

Start VMWARE Tools installation

You need to start VMware tools installation from Vmware server console or Vmware Workstation VM menu.
Click on VM Menu > Select Install Vmware Tools... > Click on Install
Start VMWARE Tools installation

Mount the VMware Tools virtual CD

If you are using guest system’s desktop, you should have mounted a CD. If you are using text mode, run mount command as follows:
# mount /dev/hdc /media

mount: block device /dev/hdc is write-protected, mounting read-only

Replace /dev/hdc with actual virtual cd rom drive.

Install the VMware Tools RPM

Finally install rpm file,
cd /media
rpm -ivh VMwareTools-1.0.3-44356.i386.rpm

Configure Vmware tools

Next you need to run the VMware Tools configuration script. You must run script from VMWare server console / Workstation and not from SSH session:
# vmware-config-tools.pl
# vmware-config-tools.pl -default

OpenBSD set up default boot time by modifying boot.conf file

Q. I’m using OpenBSD as VPS os (guest os) under VMWARE server. However OpenBSD pauses for a few seconds to give me a chance to provide parameters to the kernel at boot> prompt. I'd like to force boot loader to wait for 30 seconds instead of default timeout. How do I setup bootloader timeout?

A. OpenBSD uses boot program. The main purpose of this program is to load the system kernel while dealing with the downfalls of the PC BIOS architecture. This program acts as an enhanced boot monitor for PC systems, pro viding a common interface for the kernel to start from. By default, boot attempts to load the kernel executable /bsd. If it fails to find the kernel and no alternative kernel image has been specified, the system will be unable to boot.

/etc/boot.conf file and timeout parameter

/etc/boot.conf is configuration file for bootloader. Open file using text editor:
$ sudo vi /etc/boot.conf
Append / modify timeout parameter as follows:
set timeout 30
Save and close the file. Above line set the 30 second pause at boot-time.
