The virtual NETWORK card MAC address is editable in ESXi?

• The virtual network card speed

  When I installed first of all ESXi5, I got 100 MB switches.  I replaced all the switches in my GB rack server and all the virtual machines and no VMs shows that they are connected to 1 GB.  I downloaded a free lan speed tool to see exactly how quickly my lan speed was and I noticed something strange.  The speed test on my VM server not approached speeds GB but when I test all my virtual machines I get only 100 MB speeds.

  I noticed in the configuration of the client vSphere tab its only showing 100 full duplex MB.  I've selected the vmnic0 and chose to edit the properties and change the configuration to 1000 full duplex mb speed.  This change has dropped all my virtual machines offline and when I checked on the physical server, I noticed the NIC has no light activity.  I scrambled to understand how to fix it and finally had to use a different port on the NETWORK adapter on the physical server to deliver my virtual machines on the network.  I always show 100bm on vmnic1 speed and always make me 100 MB speeds on the lan test that I run.

  This suggests two qustions for me:

  1. why my first nic stop working when I changed the speed in vSphere and how to operate again?

  2. How can I get my mV GB speeds.

  Thanks in advance for the help!

  Well, there's your problem

  Perhaps your switch port is not configured correctly or you have some faulty wiring or a faulty NETWORK card? Go to the configuration of your network host and click the icon of the legend to the right of vmnic1. This will show you the CDP information and will tell you the interface to check.

  I also see that you are on an old patch level, I highly recommend getting on the latest version, because a NUMA scheduling patch included in this compilation which makes a big difference in performance. This is unrelated to your current number, but thought I would mention it anyway.

  You can patch in the other uplinks to see what they are negotiating to?

• If I replace my 32-bit Windows 7 with a 64-bit version, can I still keep my old files, settings of the domain network and mac address?

  We bought the RAM for one of our PC, an upgrade from 4 GB to 8 GB. Naturally, we must now upgrade Windows 7 32 bit to 64 bit.

  Our PC is running on a domain within a university network network. We have experienced some problems with one of our PC recently, so I reinstalled Windows 32 bit (no formatting). After which I simply installed the motherboard network drivers, and with one or two small parameters we were back on the domain network. Previous data has been saved to the Windows.old folder, so we kept all our old data and re-installing Windows fixed all the problems we had.

  It is therefore clear that a reinstallation of 32-bit retains all the necessary parameters to return immediately to the domain network. My question is, will an upgrade from 32 bit to 64 bit also keep the settings? Apparently, the essential is that the MAC address must remain the same, which I suppose it would be?

  I'm not so worried about the data, let's back up on an external drive anyway. The main concern is the connectivity of the network domain. If we lose this connection after the Windows Installation, you pay the University of departmental again it to the installation program.

  If you go from 32-bit to 64-bit Windows, you must perform a cleanup

• Change the binding of the virtual network card network

  Hallo,

  Since a few days, I try to get a script in orchestrator.

  When you retrieve the VirtualDeviceConfigSpec object, in the getVirtualDeviceConfigSpec() method, the method returns the blank template for the VirtualDeviceConfigSpec. To use this technique in your case, you must also specify which virtual device to change for example, you must set the virtualDeviceConfigSpec1.device property to change the network link for a virtual network device. To do the same thing, see the following steps:

  • 1 retrieve all virtual devices available to the virtual machine by using the vm.config.hardware.device property

  • 2. remove the network device appropriate for which the network link must be changed

  • 3 set the appliance recoveries of VirtualDeviceConfigSpec device. Here, you can either use the getvirtualdevicespec() method or create a new object virtualdeviceconfigspec.

  Please see below the code snippet to change the network to a virtual machine.

  Here, we provide three input parameters, namely the virtual machine whose network needs to be changed, the existing network name and the name of the new network.

  string variable existNetwork contains the name of the existing network

  string variable NouveauNetwork contains the name of the new network

  var vmspec = new VcVirtualMachineConfigSpec();

  device of var = new VcVirtualPCNet32();

  var devicearr = new Array();

  NIC var = new VcVirtualEthernetCardNetworkBackingInfo();

  nic.deviceName = NouveauNetwork;

  var devicespec = new VcVirtualDeviceConfigSpec();

  var features = vm.config.hardware.device;

  for (var I in devices)

  {

  If (devices [i] instanceof VcVirtualPCNet32)

  {

  If (.deviceInfo.summary [i] devices is existNetwork)

  {

  devicespec. Device = [i] devices;

  devicespec. Operation = VcVirtualDeviceConfigSpecOperation.edit;

  devicespec. Device.Backing = nic;

  devicearr [0] = devicespec;

  }

  }

  }

  vmspec.deviceChange = devicearr;

  task = vm.reconfigVM_Task (vmspec);

  I hope this helps.

• How to change the local IP on the virtual NETWORK adapter for Web server address

  Hi all

  I have a physical Windows system, on which I run VMware Workstation 9. Now on VMware I run Ubuntu 12.10 a LAMP for a Web server.
  Problem:
  Now, my local IP address for my NETWORK card virtual (using the Ubuntu one) at the address 192.168.159.7 and my router only emits the 10.0.0.x range IP addresses. So if I want to port forward to the virtual NETWORK adapter that has a 192.168 address, I can't, so my LAMP Web server are not accessible to the outside because the router does not send packets on port 80 to the virtual card... How to fix this?
  The only way I guess that is to be assigned an ip address of 10.0.0.x to the virtual NETWORK adapter?
  But how do I do this?
  I tried to do it on the host from the Windows machine with "get my IP address automatically", but she emits an 192.168 address every time...
  Thank you

  Welcome to the community,

  I guess that the virtual computer is currently configured to "NAT" or "Host-Only' networking! That would explain the 192.168.x.x IP address.

  There are 2 options to be able to access the web server on the virtual computer.

  1. with "NAT" network configured

  In this case forward port 80 to the IP address of the host and configure the port forwarding on the virtual computer in the "Virtual Network Editor. This way you can leave the IP address on the private network of 192 (if it is currently set to NAT)

  2. use "Bridged" network layout

  Reconfigure the virtual NETWORK adapter to the machine virtual networking "Bridged" within the parameters of the virtual machine, assign an IP address from your router network (10.x.x.x) and do the port forwarding on the router directly to the IP address of the virtual machine.

• virtual network card to the physical network mapping and default loadbalancing

  What Virtual Machine virtual network card is map physical NIC.

  For example.

  lets assume Vswitch1 on host1 esx dedicated for the network of the virtual machine (port group) and it has 6 cards network linked to it (vmnic1, vmnic2, vmnic0, vmnic3)

  Load policy (default) Balancing - from the originating virtual port (it balances only outbound traffic through all the nic assigned to vswitch1 right?)

  ESXi host1 <-Vswitch1 (the VM network) <---(vmnic 0-vmnic 3)

  Lets assume that esxi hosting 6 virtual machines and each virtual machine has two network cards configured.  Through some documents, come out of that when the virtual machine is running, it gets connected to the ports of availabe on virtual swicth. say, I turn on the virtual machine in the order VM1, VM2... VM6.

  Vmname virtual adapter port on virtual switch1 Mapping of the physical network adapter                        

  VM1 eth0, eth1 1.2 which mappeed of the physical NIC to eth0, eth1?

  VM2            eth0,eth1                              3,4                                      ?

  VM3            eth0,eth1                              5,6                                      ?

  VM4            eth0,eth1                              7,8                                      ?

  VM5            eth0,eth1                              9,10                                    ?

  VM6            eth0,eth1                              11,12                                  ?

  Since we use load balancing based on the virtual port, can two virtual map of the same virtual machine are mapped to the two physical NETWORK card I want say eth0 VM1 is mapped to the (physical nic) VMNIC0, VM1 eth1 get connected VMNIC1 (physical nic).

  It would be great if you could explain how the virtual network adapters are mapped to the physical NIC Y at - it a command or a script to the list NIC(of all vms hosted on esxi) virtual NETWORK adapter mappings physical in detail.

  Is there a way to know what virtual NIC to connect to which physical NIC

  With the virtual NETWORK adapter, you hear the virtual card inside the VM? If if and when you use several VMNIC like you, there is no visibility in vCenter (usually vSwitches, we see with Distributed vSwitches).

  However, you can use the command-line ESXTOP tool in the view 'n', for the connection between the virtual machines and the outgoing vmnic.

• Choose the right network card

  I have 2 Windows Server 2008 R2 based VMs hosted by VMware ESXi 5.0 hosts and managed by vShpere 5.0.

  Virtual machines act as an application server and a server terminal server.

  Users report poor network performance and network errors sometimes in the connection between 2 virtual machines.

  The two virtual machines are configured to use virtual network E1000 cards.

  It is advisable to change the types of VMXNET 2 or 3 VMXNET virtual network adapter?

  Should expect better performance and less network error?

  I don't see no possibility to change the type of network adapter, what is the best procedure to change the type of network adapter? Should I add a new network adapter, change the address of the existing one, configure the new with the old network adapter IP address and delete the old network card or is there a procedure better?

  Concerning

  Marius

  I did this several times.

  1. Add ethernet adapter type: VMXNET 3
  2. Now you have two network cards
  3. log on to the operating system invited
     1. Configure the IP address of the new card with the old IP address, will NOT APPLY the changes...
        1. go to vSphere Client
        2. Change the settings of the virtual machine
        3. Select the old network adapter and
           1. Uncheck the box 'connected' and the boxes ' to connect to the power supply on "under"device status ".
           2. Click OK.
        4. back to the BONE
           1. then click OK to apply the new IP address to the new network adapter.  You'll have to itself a warning saying about duplicate of IP and you asking to fix it.  Click Cancel.
  4. go back to change the settings of the virtual machine in vSphere Client
     1. and remove the old network card

• Configure the 2 network cards in a VM for MPLS LAN and the other for internet

  Dear all,

  I have a HP Server with 2 NIC cards. ESXI 4.0 is installed and 3 VM was created in it. Initially that a NIC card was connected to the path of the LAN MPLS switch and another card NETWORK was not connected to the internet switch port.

  Each VM only had a single NIC in it. So I assigned MPLS IP LAN to ESXI host and VM 3 and everything worked perfectly.

  Now, I wanted to have the internet connection for my 3 VM. So I plugged the 2nd NETWORK card with internet port and added the second NETWORK card to the ESXi using the Vsphere client - & gt; configuration - & gt; Networking option. Now the two nic cards are ponting to the network of the virtual computer.

  I've added 2 network card to all 3 VM and assigned to the internet IP addresses to all of these NICs. order of MPLS and internet work at the same time, I removed the card NIC MPLS entry door and manually routed through route add command. After this MPLS and internet worked well in 1 VM.

  I tried the same thing in 2nd and 3rd VM but it failed. whenever I have add 2nd network card in the virtual machine, the first of this virtual machine network adapter does not work.

  I'm after the right approach? Help, please...

  Kind regards

  Ashok doriane

  If I understand correctly your installation, you connected the physical NIC to two different IP networks.  Then you connected these cards in the same switch-v on the server.

  This essentially fills two different networks at the layer level 2 layer 3.

  You want rather than the two networks remain separated inside the host.

  • create a new v-switch on the host

  • move the internet NIC v-switch

  • Move the second NIC on each virtual machine to this switch

  • Make sure that access to internet VM NIC is one with a default gateway on a virtual machine OS

  • remove the default gateway of the NIC MPLS

  • creating persistent static routes to the NIC MPLS for any affected networks it beyond the same subnet as the NIC itself.  Addresses on the same subnet will be automatically accessible. Just roads for those outside this range.

• Tecra A10 - 12O: installing the driver network card in Windows Server 2003 R2 Std

  Hello

  I received 6 laptop Tecra A10 - 12O, and we need to install Windows Server 2003 R2 Standard Edition with SP2 in all these six machines. Windows Server 2003 has been installed perfectly, but now we have only the network LAN card to work but we are unable to install its driver. When I installed Windows XP from the supplied DVD for Toshiba, it says Intel 82567V Gigabit network adapter. I tried to download the drivers for this adatpor of drivers Toshiba, Intel Web site, but it will not install in Windows Server 2003. I also tried manually force to choose and install a driver from the list, I choose that it will install but shows yellow question mark in Device Manager means that it does not work with this driver.

  I also tried the same Intel 82567V drivers from some sites non-Toshiba, of these models using the same network card, but is not truck drivers at all.

  I understand these laptop computers does not support Windows Server 2003, but these were ordered to be used as servers with Windows Server 2003 Standard Edition and I am required to make the Installer only with activated and installed network adapter.

  I try last week and exhausted all means to get the installed network adapter driver, but all have failed. Can someone please help with this? All support will be highly appreciated.

  Thank you.

  Hey Buddy

  If I m not wrong Windows Server 2003 uses the same drivers as Win XP and I guess that it s driver problem not a LAN, but perhaps also the problem of Windows Server 2003 installed.

  You are right; the LAN chip seems to be Intel 82567V and the LAN driver downloaded from Intel page should work 100%.

  In your case, I would recommend installing the chipset driver.
  Remove the LAN card from Device Manager, then restart the laptop.
  Then go back to Device Manager and update driver in pointing devices Manager to the place where the driver downloaded LAN was stored on the HARD drive.

• CMS OVA, adding the second NETWORK card breaks the first NETWORK card

  I'm testing CMS 2.0 and when I try to add a second NETWORK card in VMware, he immediately interrupts the first network card.  As soon as the loading of the image, the first NIC fails.  Even if I disable iface b, it will allow all traffic where iface one.  If I stop the application, remove the NETWORK adapter and run it back again, it works very well to the iface one.

  I want to test the public face with box feature, but I can't if I can't add a second network card.

  How do you add the second network interface and interface you add?

  You should add 'VMXNET3' type if you use VMWare, if you chose something else, you invalidate your license, see section 3.3 of the virtualized CMS 2.0 Setup Guide for deployments.

  If you need assistance, you must move this thread to the section of telepresence of forums, where this device is actively discussed.  You can change your question and change the categories at the bottom of the page.

• Easy way to export and restore the virtual network editor in 10 workstation

  I'm looking for an easy way back up and restore my settings of the virtual network Editor. I use Workstation 10.0.3 on Windows 7 64 bit and have several networks configured on different host machines. After Googling for the problem, I found the following:

  -on a Linux host, the settings are stored in/etc/vmware/networking. However, I am not able to find the file in Windows. Source: http://serverfault.com/questions/535193/vmware-workstation-how-to-automate-or-script-changes-to-the-virtual-network-co

  -on a Windows host, all parameters could be saved through export of certain keys in the registry. But these keys are at least partially unique on each host, and it would be a real pain to get the keys on each host individually. Source: Re: VMware WS configuration backup

  -vnetlib control should support a statement "-export" which creates a text file containing the necessary information. However if I try to run the command, as described in the link, no file is created on my machine. The command must be ' start/wait vnetlib.exe - export path_to_file' (I am running this command of in the workplace, of course installation directory). I also tried "vnetlib" - path_to_file to export, but that did not help either. I know that vnetlib works because I reinstalled successfully the vmx86 with vnetlib service - install. If also tried the vnetlib64.exe, but no luck. Source: Re: virtual network editor

  So is - someone of you knows how to solve my problem? I'm looking for a way to write a simple batch script that exports the settings without having to deal with the registry. My virtual network Editor loses its configuration from time to time and I don't want to set up everything by hand again.

  Thanks in advance.
