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, there is an alternate approach for installing Tools, ensuring the best performance from your VM.
