Virtual machines (VMs) must have shared salt values disabled.
Low Severity
<VulnDiscussion>When salting is enabled (Mem.ShareForceSalting=1 or 2) to share a page between two virtual machines, both salt and the content of the page must be same. A salt value is a configurable advanced option for each virtual machine. The salt values can be specified manually in the virtual machine's advanced settings with the new option "sched.mem.pshare.salt". If this option is not present in the virtual machine's advanced settings, the value of the "vc.uuid" option is taken as the default value. Because the "vc.uuid" is unique to each virtual machine, by default Transparent Page Sharing (TPS) happens only among the pages belonging to a particular virtual machine (Intra-VM).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
