• The virtual NETWORK card MAC address is editable in ESXi?

  Is it possible to put the address MAC of the virtual NETWORK adapter to a custom value instead of let the hypervisor generate the MAC address for each NETWORK adapter in each computer running under ESXi virtual? I know that this is possible in workstation, server, Fusion, etc.

• Change the binding of the virtual network card network

  Hallo,

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

  here my script:

  System.log ("Start SetNics");

  virtualDeviceConfigSpec1 = new VcVirtualDeviceConfigSpec();

  virtualDeviceConfigSpec1 = System.getModule("com.vmware.library.vc.vm.spec.config").getVirtualDeviceConfigSpec (nic1, null, VcVirtualDeviceConfigSpecOperation.edit)

  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.

• 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.

• 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.

• 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.

• 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
  5. fact!

• Can not find the 2nd network card

  Hello

  I am running Server 2008 R2 on a virtual machine Workstation 8. I have two network cards on the physical basic machine (a regular cable and one wireless).

  However, I don't see the adapter wireless on my vm 2008. Literally, on the basic professional regular W7 OS, I see two adapters network from the Device Manager, but only the wired adapter from the Device Manager on the guest OS 2008.

  I have as full Server 2008 network settings.

  The two cards are activated in the base OS (in the case that has something to do with it).

  I would be grateful for any ideas about whyh, I see only the an adapter of my vm. Thank you!

  VMware has only a wired Ethernet adapter to the virtual machine, and if you want a WiFi network card in the virtual machine, then you will need to provide your own USB WiFi network adapter.

  If you're just trying to use the network adapter WiFi from the host to the bridge of one of the VMnets him and then use the virtual network Editor to remove the automatic bypass on VMnet0 and assign it the target adapter network host of choice.

• ESXi does not recognize the PCI network cards

  Good afternoon-

  I am trying to add a few new ESXi hosts to my virtual machine environment and I want my NIC integrated with the PCI NICs for tolerance to failures of the team.  ESXi is not to see the PCI network cards.  I can't find a way on how to add them to the host.  Add network cards in VC shows just the cards integrated network, the same as the ESXi console (or what there is of it).  What I'm missing here?  Thanks in advance.

  Server = PowerEdge R710

  Is what model of network interface cards?  You may need to install drivers for them - http://downloads.vmware.com/d/info/datacenter_downloads/vmware_vsphere_4/4#drivers_tools.

• Call "HostNetworkSystem.UpdateVirtualSwitch" for the error of the object when you attempt to add the second NETWORK card

  Hi there - first post here, so please be nice :-).

  We are just trying to place an ESX4.1 own deployment in our environment (no previous installation of VMWare) to our main office, using Dell M610 and blades blades M600 to what would become our DR - two sites site hosting VMS on Equallogic iSCSI SAN disks.

  I configured 4 of our blade M610 with ESX 4.1 successfully and they work very well.  These blades have double NIC onboard, and after the initial installation of ESX, I could go to the virtual switch and add in the second NIC like vmnic1 (because one had already been detected during installation).  This fine workd for 4 guests on the M610 blades.  However, I came today to make my first installation on one of the old M600 blades and I encountered a problem.

  Installation went without any problems and I was able to add the host in my vCenter.  I can change all the settings without problem (created the Port of VMKernal for my connection to SAN iSCSI etc, but as soon as I try to add in the second NETWORK card, he paused for a while, and then I get the following error message:)

  Call 'HostNetworkSystem.UpdateVirtualSwitch' of object 'networkSystem-56 "on vCenter Server"VCEN01." ournetwork.local"failed. (network name has been changed for post).  When this happens, it locks up again for several seconds, and when the system returns, I can no longer communicate with the ESX host (Observer of events in vCenter watch 'host is not responding' and I find that I can not ping the host unless I reboot it.)

  If anyone has any suggestions I would appreciate it that I don't want to proceed down to the line with our Installer if theres an underlying issue and I need to redo everything.

  Concerning

  EFIN.

  Do you get the same error when you try to add the network adapter by using the command line?

• Add the second NETWORK card to vSwitch

  I'm working on trying to add to install a second NIC physical to the vswitch which is installed by default when ESXi. I use the code below, but when I run it, it disconnects in fact the main physical network card and of course, I then lose connection. I tried different varients of this and even finished by adding a port of vmk, which I didn't do. I just want to add the second network card as a standby card network.

  #Add second NIC to the virtual switch
  $nic = Get-VirtualSwitch -VMHost $currentHost -Name "vSwitch0"
  Set-VirtualSwitch -VirtualSwitch $nic -Nic vmnic1
  

  The cmdlet Set-VirtualSwitch accepts a string array as the value of the parameter - Nic. So you should be able to:

  #Add second NIC to the virtual switch
  $nic = Get-VirtualSwitch -VMHost $currentHost -Name "vSwitch0"
  Set-VirtualSwitch -VirtualSwitch $nic -Nic vmnic1,vmnic2

• Can not see the physical adapters in the virtual network Editor

  I installed VMware Server 2.0 on my computer running Windows 7 64-bit edition Home premium.  I'm trying to make sure that the network card virtual vmnet0 only connects to my thread of material gigabit NIC, not my wireless card.  I went into the virtual network editor and none of my physical computer network cards are listed.  The bridge networks tab the checkbox next to automatically connect to the network device is checked and grayed out.  Any ideas on why my physical network cards are not listed.  Thank you.

• 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.

• Add a virtual network card

  Hello

  Is it possible to add a VM virtual network card, and not a phyiscal adapter?

  I hope to run a quick RLV connecting virtual machines.

  It seems that this is possible, but I couldn't make it work.

  Can you please direct me to a URL or explain how it is possible?

  Thank you very much.

  You can create a vSwitch who doesn't have a card assigned to it, then within your VMS physical NETWORK add virtual NICs attached to this vSwitch for a private local network.   That said, when the VMs are on the same vSwitch and VM network communication inter subnet does not go out to the physical NIC port.

• Impossible to locate or select network adapters in the virtual network editor - W2K8 host

  I am running VMware 2.0.1 on a W2K8 64-bit host (with the windows firewall is disabled for now). VM images are all able to start and use the network bridged the host connection. I can access these images of virtual computer on the network, and even each image virtual machine running on that host computer has access to the public network.

  My problem is that I have three network adapters available on the host, but I can't individually select one of them in the virtual network Editor. The "Automatic gateways" checkbox is grayed, outside, tab automatic bypass, and if I try to select an adapter to exclude none appear in the dialog 'Add adapters excluded' that opens. In the virtual network mapping tab VMnet0 host, is set to be filled to an automatically chosen adapter and VMnet1 & 8 are configured to use their default VMware network cards. If I open the selections from drop down menu to one of the network adapter 10 VMnets listed in the virtual network mapping tab host there is no available alternative.

  Note: three network cards available on my W2K8 host server, one of them is a fault tolerant team consisting of two individual adapters and two other network cards are not associated. The team of the adapter has a network on our local network connection, but the other two adapters are connected to a private network. The fact that the images of the virtual machine running on that host are available on the network and be able to use the network indicates to me that my VMnet0 connection automatically open is finding and using the adapters together somehow (Luckily, by design?).

  I installed VMware 1.X and 2.0 on many host W2K3 servers and never encountered this problem before.

  If Win2008 follows a similar to Vista security model, then you must run AS administrator virtual network Editor.  Otherwise, you cannot make changes selections.
