The modules also support quiescing snapshot on Linux OS Virtual Audio Driver VMCI and VMCI Sockets drivers The Virtual Machine Communication Interface driver supports fast and efficient communication between virtual machines and the hosts they run on. During the snapshotting process, certain processes are paused and virtual machine disks are quiesced. These modules allow external third-party backup software that is integrated with vSphere to create application-consistent snapshots. For other, earlier Windows operating systems, the Filesystem Sync driver is installed. Modules and drivers that support making automatic backups of virtual machines If the guest operating system is Windows Vista, Windows Server 2003, or other newer Windows operating systems, a Volume Shadow Copy Services (VSS) module is installed. Excluding this driver hinders the memory management capabilities of the virtual machine in a vSphere deployment.

Memory control driver This driver is required for memory ballooning and is recommended if you use VMware vSphere. Network Introspection Driver: The Network Introspection driver supports NSX for vSphere Activity Monitoring.This strategy avoids resource bottlenecks and optimizes memory use. File Introspection Driver: The File Introspection driver uses the hypervisor to perform antivirus scans without a bulky agent.When you install VMware Tools, by default, the Guest Introspection drivers are not installed. You can install the two drivers separately.

Guest Introspection Driver The two Guest Introspection drivers are the File Introspection driver and the Network Introspection driver.
