Looking for VMware Tools?

Looking for VMware Tools? Look no further than your ESX host under /vmimages/tools-isoimages. There you’ll find the .iso files that mount as images into the virtual CD-ROM tray when the “Install/Upgrade VMware Tools” command is passed to the ESX host for a VM. Under the floppies folder you’ll find vmscsi-1.2.0.2.flp which is the optimized BusLogic SCSI driver for legacy Windows guests.

su command

At the ESX Service Console, use the su command to change users. su is short for substitute user or switch user and is typically used for the elevation of privileges. I liken it much to Windows Fast User Switching. The bottom line is that su provides a method for admins to log on with their own accounts and to use su - for root privileges when needed, while providing an audit trial. It's a good security measure.

Clearing The Air On Shares

Clearing The Air On Shares

Share values are a method of allocating CPU and memory resources to VMs with preference in an over commit situation. Shares can be assigned individually in the VM configuration, or more globally at the resource pool level. What's often forgotten is that shares only come into play when a shortage of CPU or memory actually occurs. Outside of a resource shortage, shares don't do a darned thing.
