Installed out of the box – The primary benefit of OVT is the fact, that Linux distros have in most cases incorporated those packages within the installation ISO so when you create a new Linux VM within your environment and you’re using this installation ISO, most likely the OVT will be installed out-of-the-box. OVT are also responsible for clock synchronization between guest and host, as well as quiescing of guest file systems which is needed for filesystem consistent guest snapshots. With OVT you’ll be able to perform graceful shutdown, authentication for guest OS operations, generation of heartbeat from guest to host (so VMware High Availability can determine if the guest OS is up and running or not). It has kernel modules for enhancing the performance of VMs running Linux or another VMware supported Unix like guest OS. The same as VMware tools, OVT is suite of virtualization utilities which improves the performance, functionality, administration and management of virtual machines (VMs) running within VMware vSphere environment. Open-VM tools (OVT) is an open source implementation of VMware tools. What are the differences between VMware Tools and Open-VM tools? These modules allow external third-party back up 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. This driver is required if you use third-party tools such as Microsoft Terminal Services. Mouse Driver – The virtual mouse driver improves mouse performance. Drivers for other storage adapters are either bundled with the operating system, or they are available from third-party vendors. This driver for VMware Paravirtual SCSI adapters enhances the performance of some virtualized applications. Paravirtual SCSI Driver – A VMware Paravirtual SCSI driver is included for use with Paravirtual SCSI devices. AppDefense agent can be installed on the guest virtual machine using the VMware Tools installer. Here are few examples of services that can be (or are ) installed by default when you install your VMware Tools package inside of your Virtual Machine (VM).Īppdefense – (not installed by default) VMware Tools installation include the VMware AppDefense, a security management and monitoring solution. VMware tools can run services that helps with VM workloads. ![]()
