Adding a shared disk in Workstation 6.0

Filed under: Scripting,Tools,White Papers,Workstation — A. Mikkelsen @ 14:19 pm

Edit and add the following to the VMX file :

scsi1.present = “TRUE”
scsi1.virtualDev = “lsilogic”
scsi1.sharedBus = “virtual”
disk.locking = “false”
scsi1:0.present = “TRUE”
scsi1:0.fileName = “Shared.vmdk”

Notice that the SCSI target is 1:0 and not 0:1

After this you should be able share the disk between 2 VM’s.

Script to power off all VM’s

Filed under: Scripting — A. Mikkelsen @ 20:34 pm

Here is at BASH script to power off all active VM’s on a host.

#!/bin/bash
IFS=’

for vm in `vmware-cmd -l`
do
        name=`vmware-cmd “$vm” getconfig displayname -q`
        state=`vmware-cmd  “$vm” getstate -q`
        if [ “$state” == “on” ]
        then
                echo “Trying to power off $name….”
                output=`vmware-cmd “$vm” stop trysoft`
            if [ $? -eq 0 ]; then
                echo “$name was powered off successfully.”
            fi
    fi
done

The script was posted by Alex at the VMTN forum a while back, but is now updated so i reports if the VM is powered off succesfully.

Cool add-on to Virtual Center 2.x from Run-virtual.com

Filed under: Tools,Virtual Center — A. Mikkelsen @ 12:11 pm

Someone informed me on this very usefull add-on for Virtual Center 2.x.

VCplus           – http://www.run-virtual.com/?page_id=184

Haven’t tried it myself yet, but i will during next week.
I think that this add-on is a step in the right direction. Mayby VMware should implement this add-on in VC.

Nice job Richard …. Keep it up….
