Term
What does the VIrtual Machine Hardware version dictate?
Definition
The hardware devices and types/versions of hardware devices available to a VM
Term
Where can you check what hardware version is on your VM?
Definition
In the summary tab there is a 'VM Version' field
Term
What capabilities does Virtual Hardware Version 8 provide?
Definition
Compatible with ESXi 5.0 and later hosts. Latest VM features including 3D graphics and HD Audio, SmartCard Reader, USB 3, new driver for e1000. It can take up to 1TB of RAM and 32vCPUs
Term
What capabilities does Virtual Hardware Version 7 Provide?
Definition
Compatibility with ESX/ESXi 4.x and above hosts. REcommended for sharing storage or VMs with ESX/ESXi versions 3.5 to 4.1. Introduced Changed Block Tracking (CBT), Hotplug, VMXNET 3, IDE Virtual Devices, SAS virtual devices. Has the ability for 255GB RAM and 8vCPUs.
Term
What capabilities does Virtual Hardware Version 4 have?
Definition
Compatible with ESX/ESXi 3.0 and later hosts (ESXi 5.x can edit/configure, but not create these VMs). Recommended for VMs that need to run on ESX/ESXi 3.x hosts. Ability for 64GB of RAM (3.5 up from 16GB of RAM) and 4 vCPUs
Term
List 5 VMware Tools Device Drivers
Definition
SVGA Driver, SCSI Driver, Paravirtual SCSI Driver, VMXNet NIC Drivers, Mouse Driver, Audio Driver, Kernel Module for Sharing Folder, ThinPrint Driver, Memory Control Driver, Modules and Drivers that support making automatic backups, VMCI and VMCI Sockets Drivers
Term
Describe the SVGA VMware Tools Driver
Definition
This virtual driver enabled 32-bit display, high display resolution, and significantly faster graphics performance. When you install VMware Tools, a virtual SVGA driver replaces the default VGA driver, which allows for only 640 x 480 resolution and 16-bit colour
Term
Describe the SCSI Driver
Definition
When you create a virtual machine, if you specify that you want the virtual machine to use a BusLogic adapter, the guest operating system uses the SCSI driver that VMware Tools provides. An exception is made in recent guest OS's where they may default to LSI Logic SAS or another driver that is inbuilt that provides the best performance for that OS.
Term
Describe the Paravirtual SCSI Driver
Definition
Paravirtual SCSI adapters enhance the performance of some virtualized applications. This VMware Tools driver supports those adapters.
Term
Describe the VMXNet NIC Drivers
Definition
The vmxnet and vmxnet3 networking drivers improve network performance. Which driver is used depends on how you configure device settings for the virtual machine. When you install VMware Tools, a VMXNet NIC driver replaces the default driver
Term
Describe the Mouse Driver
Definition
Improves mouse performance. This driver is required for some third party tools such as Terminal Services.
Term
Describe the Audio Driver
Definition
Required for all 64-bit Windows OS's and 32-bit Windows Server 2003, Windows Server 2008 and Vista guest operating systems if you use the virtual machine with VMware Server, Worstation or Fusion
Term
Describe the Kernel Module for Sharing Folder
Definition
The host-guest file system module, called hgfs.sys on Windows guest operating systems and vmhgfs on Linux and Solaris, is required to use the VM with Workstation or Fusion and share folders between hosts and guests
Term
Describe the ThinPrint Driver
Definition
This driver enables the virtual printing feature on Microsoft Windows virtual machines. With virtual printing, printers added to the operating system on the client or host appear in the list of available printers in teh guest operating system. No additional print drivers must be installed in the VM.
Term
Describe the Memory Control Driver
Definition
The driver is available and recommended if you use VMware vSphere. Excluding this driver hinders the memory management capabilities of the Virtual Machine in a vSphere deployment
Term
What is the function of modules and drivers that support making automated backups?
Definition
If the guest OS is Windows Vista, Windows Server 2003, or other newer Windows OS's , a Shadow Copy Services (VSS) module is installed. For other, older Windows OS's, the Filesystem Sync driver is installed. These modules enable backup applications to create application-consistent snapshots. During the snapshotting process, certain processes are paused and virtual machine disks are quiesced
Term
Describe the VMCI and VMCI Sockets Drivers
Definition
The Virtual Machine Communication Interface driver allows fast and efficient communications between virtual machines. Developers can write client-server applications to teh VMCI Sock (vSock) interface to make use of the VMCI virtual device.
Term
Name two locations you can install/upgrade VMware tools
Definition
1. vSphere client - right click VM and select 'Guest' -> Install/Upgrade VMware Tools
2. Console menu of the VM
Term
T/F: Automatic installation of VMware tools will re-boot the VM
Definition
True
