Aug 04, 2018 · For sure the meltdown/spectre bios patches together with updated EVC modes are the trigger of the problem. We always fix it by creating a new cluster and moving the hosts into it followed by most of the VMs by performing a vMotion. At the end we often have a couple of VMs which cant be vMotion'd and we have to shutdown these VMs to move them.
