vSphere - Sluggish mouse on Windows 7 and 2008 Server

I had this issue after installing Windows 2008 R2 on VMWare ESX 4.0 (208111). Even though I installed VMWare tools, the mouse was still acting as if the driver wasn't installed - the mouse is jumpy and is not leaving the console after the "real" mouse is exiting the screen.

It seems that VMWare is aware of this issue and will solve it eventually.

Anyway, this is the quick fix:
  • install VMWare Tools in your machine, reboot;
  • VMWare tools has created the folder: C:\Program Files\Common Files\VMware\Drivers\wddm_video;
  • go to Device Manager, to your video adapter and select "Update driver";
  • when asked for the files, browse to the folder above;
  • reboot;
  • problem fixed!
LE: after every VMWare tools update you need to redo these steps.

    Integrating VMWare ESX into your enterprise network with VLANs, trunking, load balancing

    VMWare ESX 3 and VSphere can fit nicely into your enterprise network, adding unprecedented flexibility and functionality; after you've got the taste you'll be hooked on it. Virtual machines can be moved from one VLAN to another with a few cliks.
    First of all, about load balancing... If you have VSphere installed on an enterprise server then you most likely have 2 gigabit network interfaces at your disposal. These NICs can be "teamed" for load balancing and failover purposes. As you will see further in the article, load balancing will work even if the swith doesn't support load balancing, but it will only work for outgoing traffic. To make the most of load balancing you need to use a switch that supports etherchannel; in this way the switch will send traffic to the server on both ports, based on the load balancing scheme we configure. In this example we'll be using the Cisco Catalyst 2960G switch.
    You can find network configuration of the ESX host on tab Configuration - section Hardware - Networking. You'll probably use vSwitch0 to configure your network interfaces and VLANs. At first you'll have only one NIC added to the vSwitch. You need to add the second interface. Go to the properties of vSwitch0, go to Network Adapters and click on Add to add the other interface; this is how vSwtich0 will look like aftewards:




    Go back to Ports on the tab above to configure load balancing. Edit the vSwitch device and go to NIC teaming. In this example we'll be using load balancing based on IP hash. So configure "Route based on ip hash" in the Load balancing section:




    Next step is to configure the switch. In this first phase we assume that you're running the ESX server in access mode (no VLAN trunking), in VLAN10. Identify the ports in the switch that belong to the ESX server and configure the port channel (we'll assume that you don't have any other port channels configured):

    sw(config)#interface range g0/1 - 2
    sw(config-if-range)#switchport mode access
    sw(config-if-range)#switchport access vlan 10
    sw(config-if-range)#channel-group 1 mode on

    Now the communication with the ESX should work; if not, take the ports out of the port channel and fix your configuration.
    If everything is ok now, we can prepare the ESX server for VLAN trunking. We need to put the Service Console interface on the desired VLAN - for example, VLAN 10: go to the properties of vSwitch0 and edit the Service Console; click on "Continue modifying the connection" to pass that warning; type your VLAN ID in the next window:




    At this point you will lose connectivity to the ESX server. To restore it, configure VLAN trunking on the switch:

    sw(config)#interface port-channel 1
    sw(config-if)#switchport mode trunk
    sw(config)#interface range g0/1 - 2
    sw(config-if-range)#switchport mode trunk

    If you have VMotion or iSCSI or NFS volumes configured, then you need to configure also the VMkernel VLAN, in the same way you configured the Service Console.

    In case something goes wrong and you need to troubleshoot you configuration:

    - you can check the etherchannel load balancing on the switch:

    sw#show etherchannel load-balance
    EtherChannel Load-Balancing Configuration:
    src-dst-ip
    EtherChannel Load-Balancing Addresses Used Per-Protocol:
    Non-IP: Source XOR Destination MAC addressIPv4: Source XOR Destination IP address
    IPv6: Source XOR Destination IP address

    - you can log in to the ESX server console and, for example, configure the VLAN ID of the service console:

    [root@server root]# esxcfg-vswitch -v -p “Service Console” vSwitch0

    To add a VLAN for your virtual machines go to vSwtich0 properties and "Add...", choose connection type "Virtual machine", type your VLAN name for easy identification and the VLAN ID:



    Then, moving the virtual machines from one VLAN to another is simple: edit settings on the desired virtual machine and select the network adapter; on the network label drop-down list you will get the VLAN you configured.
