Announcement: VMware Response to Speculative Execution security issues CVE-2017-5753, CVE-2017-5715, CVE-2017-5754 (aka Spectre and Meltdown)

On January 3, 2018, it became public that CPU data cache timing can be abused by software to efficiently leak information out of mis-speculated CPU execution, leading to (at worst) arbitrary virtual memory read vulnerabilities across local security boundaries in various contexts. 

Three variants have been recently discovered by Google Project Zero and other security researchers; these can affect many modern processors, including certain processors by Intel, AMD and ARM.

Discontinued processors support in vSphere 6.5

During an installation or upgrade, the installer checks the compatibility of the host CPU with vSphere 6.5.

If your host hardware is not compatible, a purple screen (PSOD) appears with an incompatibility information message, and the vSphere 6.5 installation process stops.

vSphere 6.5 no longer supports the following processors:
  • Intel Xeon 51xx series 
  • Intel Xeon 30xx series 
  • Intel core 2 duo 6xxx series 
  • Intel Xeon 32xx series 
  • Intel core 2 quad 6xxx series 
  • Intel Xeon 53xx series 
  • Intel Xeon 72xx/73xx series
