Information
The ESXi host must restrict inter-VM transparent page sharing to VMs configured with sched.mem.pshare.salt. Transparent Page Sharing (TPS) is a method used to reduce the memory usage of virtual machines. However, under specific conditions, it can potentially be exploited to gain unauthorized access to data on neighboring virtual machines. Virtual machines that do not have the sched.mem.pshare.salt option set are unable to share memory with any other virtual machines, providing an additional layer of isolation and security.
Solution
Get-VMHost -Name $ESXi | Get-AdvancedSetting Mem.ShareForceSalting | Set-AdvancedSetting -Value 2
