Enabling copy and paste in vSphere client

Starting with vSphere 4.1, the Copy and Paste options are, by default, disabled for security reasons.
To be able to copy and paste between the guest operating system and the remote console, you must enable the Copy and Paste options using the vSphere Client. Alternatively, you can use RDP (Remote Desktop Protocol) to connect to the Windows virtual machines.
To enable this option for a specific virtual machine:
  1. Log into a vCenter Server system using the vSphere Client and power off the virtual machine.
  2. Select the virtual machine and click the Summary tab.
  3. Click Edit Settings.
  4. Navigate to Options > Advanced > General and click Configuration Parameters.
  5. Click Add Row and type the following values in the Name and Value columns:
    • isolation.tools.copy.disable – false
    • isolation.tools.paste.disable – false
      Note: These options override any settings made in the VMware Tools control panel of the guest operating system.
  6. Click OK to close the Configuration Parameters dialog, and click OK again to close the Virtual Machine Properties dialog.
  7. Power on the virtual machine.
Note: If you vMotion a virtual machine to a host where the isolation.tools.*="FALSE" is already set, the copy and paste options are automatically activated for that virtual machine.
To enable this option for all the virtual machines in the ESX/ESXi host:
  1. Log in to the ESX/ESXi host as a root user and open the /etc/vmware/config file using a text editor.
  2. Add these entries to the file:

    isolation.tools.copy.disable="FALSE"
    isolation.tools.paste.disable="FALSE"

  3. Save and close the file. The Copy and Paste options are only enabled when the virtual machines restart or resume the next time.

NoteThese options do not persist after an upgrade. If you upgrade to a newer version after enabling these options, the changes are lost and you may have to re-enable them.
Note: An RDP session to Windows virtual machines lets you copy and paste.

Basically the faster frame forwarding rate and the higher the port buffer the better, which is how you gauge a good switch.


*0.75MB of ingress buffering is dynamically divided into port
buffers/queues, 2 of which are user-configurable. There's 2MB of
egress buffering that provides 4 egress queues per physical port.

Slow mouse performance on Windows 2008 R2 virtual machine

Troubleshooting SVGA drivers installed with VMware Tools on Windows 7 and Windows 2008 R2 running on ESX 4.0

■You receive a black screen on the virtual machine when using Windows 7 or Windows 2008 R2 as a guest operating system on ESX 4.0.
■You experience slow mouse performance on Windows 2008 R2 virtual machine.
Solution

This issue can occur due to the XPDM (SVGA) driver provided with VMware Tools. This is a legacy Windows driver and is not supported on Windows 7 and Windows 2008 R2 guest operating systems.


To resolve this issue, update to ESX 4.0 Update 1. A new WDDM driver is installed with the updated VMware Tools and is compatible with Windows 7 and Windows 2008 R2.


Note: After a VMware Tools upgrade, the driver files are located in.

C:\Program Files\Common Files\VMware\Drivers\wddm_video.

Dell R610 - Tylersburg chipset stepping for Westmere processors

Tylersburg chipset stepping for Westmere processors
Introduction of the new Intel Xeon 5600 series (Westmere-EP) processors includes a stepping revision of the Intel 5520 and 5500 chipset from ‘B3’ to ‘C2’. This stepping revision is required to enable the full Xeon 5600 processor feature set. Dell servers shipped with the new chipset revision will have the symbol II in the BIOS System Revision Field, which is visible through Open Manage Server Administrator (OMSA) and the iDRAC GUI. In addition, these servers will be physically marked with a 12mm wide by 6mm tall rectangular label containing the symbol “II” will be. They will be white characters on a black background.
The II symbol also identifies R610 servers with system boards that support 130W processors. 130W processors on R610 require a unique heatsink.PowerEdge R610 (Thidwick) Sourcebook Dell Confidential – For Internal Use Only 35
Intel Xeon 5600 series processors will work in existing systems built for Intel Xeon 5500 series (Nehalem-EP), however the full feature set including AES-NI encryption and Intel TXT will only be available in newly manufactured systems which include the new Westmere-EP (C2) stepping of the system chipset. In addition, existing systems will not support the top bin 130W Xeon 5600 processors.
A BIOS and iDRAC update to current versions are required before installing 5600 series processors in systems originally shipped with Nehalem EP 5500 series processors.
