Eric Gray from vCritical posted a good article in regards to the usage of SLES for VMware and installing VMware Tools. Since the release of SLES for VMware, I would assume we might see a jump in the use of SLES throughout the virtualized SLES shops. SLES is a pretty popular distribution to begin with and has seem to be relatively stable. Eric states:
Virtual machines are not fully functional until VMware Tools are installed in each guest operating system. If you are using [SLES for VMware](http://www.vcritical.com/2010/09/sles-for-vmware-first-look/), there is an alternate approach for installing Tools, ensuring the best performance from your VM.
