Hi starwrz

"Hypervisor-Specific Mitigation

Mitigates leakage from the hypervisor or guest VMs into a malicious guest VM. VMware’s hypervisor products are affected by the known examples of variant 1 and variant 2 vulnerabilities and do require the associated mitigations. Known examples of variant 3 do not affect VMware hypervisor products.

VMware hypervisors do not require the new speculative-execution control mechanism to achieve this class of mitigation and therefore these types of updates can be installed on any currently supported processor. No significant performance degradation is expected for VMware’s hypervisor-specific mitigations."

Cheers,
