• Configure the virtual server to 2003 to use two physical network adapters on the host

  I have a virtual server (Server 2003) that I'm trying to point two virtual NETWORK card to two different physical NICS on the host computer.  The two network adapters on the host are on separate networks, and I can't get virtual network cards to connect properly.

  I use VMWARE Server 2 with the virtual network manager.  All good instructions would be greatly appreciated.

  Thank you

  Run the virtual network Editor.  Disable the automatic bypass.  Then, specify which of your physical NIC to the bridge to VMnet0 and specify the other physical NETWORK adapter on one of the switches (2-7, 9) unused VMnet.  In the settings of your virtual machine, select a virtual NETWORK adapter to be filled, and a 2nd we use custom connection and specify what VMnet switch to use (the one you filled the 2nd NETWORK card physical to).

• URGENT! Two physical network with two subnets completely - no bridges - interface cannot connect both

  This is my urgent problem:

  I have a physical machine with two physical network interfaces. I have a VMWARE player and a virtual machine that must use cards on two different subnets, a public directly to the router and an intranet within the company.

  How can I just say a net card to go on this submarine and the other on the public void?  Go crazy. Help, please.

  Thank you

  P.

  Use the virtual network editor VMware Player, create an additional bridged VMnet and bind each bridged to a different physical network... card VMnet on a virtual machine, create a virtual network adapter on each subnet and bind each virtual network adapter to an another VMnet jumpered.

• Mapping of several physical network adapters to virtual network adapters

  Hi all

  I am wanting to know how to combine physical network adapters to virtual nics in Vsphere 4.1. I have a gateway virtualized device that supports multiple WAN connections and balancing on these connections. The bridge is all authentication PPPoE/A, so I need to have separate cards for each PPP connection. So, how can I connect a physical NETWORK adapter to a virtual NETWORK adapter and have all access the same VM virtual NIC?

  Hope that makes sense!

  James

  Right-click on the virtual machine, and then select change settings. On the Hardware tab, click Add, and then add the virtual NICs that you will need.  On the network connection screen, you will be able to select a network label which corresponds to VM port groups you created.

• VM simple Load Balancing with 4 physical network adapters

  I have one main server with 4 cards of physical network dedicated to this server in a vSwitch. I wanted to know the proper way to balancing configuration in vSphere to allow a theoretical throughput of 4 Gbit/s. The options I have, as you know:

  1. Port according to ID - this the method by default when you have 2 or more physical NIC connected to a virtual switch. The VM traffic is realized on a physical NETWORK card based on the VMs virtual port ID and is incremented in the style of round robin. So if you have 2 NICs physical network, the first drop of will traffic VMs that the first NIC, the second VM shuts down to the second NIC, third comes out first NETWORK card and operating system on - host ESXi does not resemble the traffic so if VMs 1,3,5 are heavy network users they will go on the same NETWORK adapter even if the second NETWORK card can be totally unused
  2. Address based MAC - based similar to port, but the physical NETWORK adapter is selected according to the MAC address of virtual machines
  3. IP hash database - the physical NETWORK adapter is selected based on the starting and destination IP address - so if a virtual machine connect to several IP addresses that traffic will be disttibuted on all physical network cards - note this will require LACp be configured on the physical spend this ost ESXi connects to

  The first two sound me as they would give me what I want from the physical NIC selection is based on the virtual source, not the destination machine. So, since I have only a virtual computer, the LB would never use a physical NIC and I'd be stuck with 1 Gbps.

  The third option seems more promising, but I do not have much exposure to the management switch. LACP would be similar to the creation of a trunk on my 3Com switch 2848 reference? It seems likely, but I wanted to run it by the experts to make sure.

  Thank you!

  EDIT: I think I just found the killer. Cited in the manual for my switch:

  The switch does not support the aggregation of links
  Protocol LACP (Control), which is specified in the IEEE standard
  802.3ad.

  Does that mean I'm desperate to do my 4 Gbps with the swithc and I MUST get a LACP switch?

  You will need either LACP or EtherChannel on your switch upstream to support IP hash configuration, install, configure, manage Volume 1 book for ESXi 5.0. With hash IP, MAC address of the virtual computer may appear on any of the physical interfaces available for the vSwitch (at least for the outbound traffic), which would cause problems on the side of the physical switch unless a method of aggregation (LACP or EtherChannel) link type is enabled.

• Additional physical network adapters on host VMware ESXi 3.5

  I would like to add additional physical network cards to host VMware ESX 3.5 (update 3). I installed two PCIe Intel NIC (E1G42ET) server for the HP ProLiant DL 380 G5 server. Both NIC cards recognized by the BIOS of the server.

  After you connect to the VMware VI Client I can't see or add new maps.

  In addition, new non-visible material in the host ESX console.

  You are not sure if the drivers of NETWORK interface card must be installed manually?

  Hello

  VMware ESX is NOT Linux, there a GNU/Linux management machinery... ESXi is not even there a device for managing Posix. Drivers for Linux won't work with ESX or ESXi. If the card is not without the HCL for ESX/ESXi, then it won't work with ESX/ESXi. Usually not in list HCL implies VMware doesn't have a driver yet for this card. All drivers must come from VMware ESX and ESXi recognize the hardware.

• How can I associate the virtual machine to the physical NETWORK card?

  Hello

  I have a host, has two physical network adapters.

  I want to use one for VM and give an ip address for this but I do not know how to configure it. In my view, "Manage virtual networks" fuction for this...

  Thank you!

  You should already have a phyiscal WHAT NIC assigned to VMnet0 (bridged). So if the choice as vonnection for a guest. Create a second connection open by assigning the physical NIC then to VMnet2, for example (VMnet1 is already in use). Assign this connection to the second guest.

• Grouping of active/active network adapters

  I have two 6509 cisco switch

  I have configured the two physical network adapters on ESX 4.1 as active/active and they are connected to a NIC in each switch.

  That way I have more flow?

  How ESX handles the traffic in the pool of active/active NETWORK adapters?

  As I understand it, (even once that caveat, not a network) you cannot extend a vswitch on switch ports without a violation of the spanning tree protocols that disables anything but a port UNLESS your links aggregation switches battery cross. Someone correct me if I'm wrong, please.

  You are right. There is some confusion of terms only.

  There is a network standard called 802.3ad (working group name) or 802.1AX (real name now, but the name sticks around the working group.) This explains how two units may group several links together and logically to treat them as one. On Cisco switches, this is called an 'association' on the HP Procurve switches, this is called a 'trunk', and on most servers, this is called a "NIC team." On ESX, it is called "IP hash.

  Both parties must be configured to do so, otherwise the same MAC address is displayed both on different ports and this would cause various problems, including trouble of Spanning Tree, but also other things.

  The 802.3ad has two modes, a static configuration, or dynamics of the aggregation of links. The static method is quite simple, the two sides should only be configured manually. When you use dynamic a certain protocol called LACP is used to negotiate it. Cisco also has its own propertiary Protocol PaGP that does the same thing.

  The host ESX/ESXi only has support for aggregation of static links, so this must also be set on the side of the physical switch.

  The 802.3ad/802.1AX does not specify HOW loads should be balanced across the available links. It is up to the different units to decide and it could very well be different on two sides of it without problem.

  Various switches (physics and also the Vmware vSwitch) uses a method that includes IP addresses in the source and the destination to choose a NIC out this load balancing works well and is quite simple to do, but the boundaries a session between two periods of investigation to a single network adapter. If the connection fails, it will go to another.

  Some switches have the possibiliy to use more advanced algorithms to do this, including for example src/dst IP and also the TCP port numbers. It is more "expensive" to do what the package should be inspected deeper and also cause more general CPU, but will allow the load between two IP hosts use multiple network interface cards. It is not supported on the standard vSwitch or the distributed switch, but on the 3rd party Nexus 1000v.

  However, all methods is the aggregation of links, some differences in how to place images on the network adapters.

  As for using two different physical switches standard does not allow this. Aggregated links must begin and end between the two groups. However, several switch suppliers (for example, Cisco and HP) formed their own solutions for this, called stacked Switch Etherchannel or Trunking distributed for example.

  IF you have these switches with this function and if set up correctly on the side of the switch, you can for example set four vmnic "hash IP" on your ESX/ESXi and connect these two physical switches. This would probably be the best combination of fault tolerance and load balancing.

• Grouping of NETWORK adapters and NLB on ESXi 3.5

  I want to get ESXi to load balance the traffic to my NFS storage, but have had no success. My test set up is the following:

  • Two blades each with two physical network adapters dedicated to the ESXi for NFS kernel ports

  • Two switches

  • A NETWORK adapter on each blade is connected to each switch - it isn't an Etherchannel or trunking configured

  • Two NFS devices on a different IP address

  • Eight virtual machines on each blade, four to connect to a data store on each device of NFS

  • ESXi NIC teaming across two network cards with the option "route based on the virtual origin of switch port code.

  My understanding is that each virtual computer must use one of the network cards, but about half must use a physical NETWORK card and half the other. Instead, all the traffic of all eight VMs released a physical NIC if I disable the physical NIC, it moves the second NETWORK card without problem. Then they both work, but he never uses both at the same time. This behavior is consistent across the two blades.

  Is throughbut limited to ~ 110 MB per blade and the storage system can easily exceed this.

  I've attached a screenshot of a virtual switch in place.

  TIA,

  Will be

  Virtual machines are access NFS data warehouses directly? If Yes, then yes it should work that way - however if you are using the NFS data store to host the VM files, including virtual disks and then traffic will turn off the vmkernel port and if have vmkernel unique port then what you are experiencing is expected - the vmkernel selects the outgoing NIC based on the virtual port id so if you have a single port vmkernel will suffice a single port as well as a NETWORK identifier unique will be used.

• Configuration of the network adapters physical vSwitches

  Hello! I am currently in operation 1 Server ESXi 4.1, a switch Dell PowerConnect 2708 (8 ports) and 2 vSwitches.

  My question is this:

  Why don't my ESXi / vCenter server detects the physical or the various Dell switch ports? I can only see 1 physical adapter that is my card physical BroadCom that is installed on the physical server ESXi. From what I've studied, I've seen users ESXi / vCenter Server able to detect at least 1 or 2 cards physical on their Cisco switches.

  Is the problem the manufacturer? Dell or Cisco? I can only now see 2 physical network adapters on my server vCenter Server "vmnic0" which is upward and enforcement connected to my main switch which has to internet access. And "vmnic32" under "Gigabit Ethernet PCIe" which is down and waiting, which I'm unable to set up at all.

  I just need 1 physical adapter to connect to my newly created another vSwitch. Please give helpful suggestions! Thank you!!!

  The Dell switch must support CDP, if it is not, you will not see any information on the Dell switch - two NETWORK ports are pligged of network cables?

• 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                                      ?

  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.

• Advice on how best to configure the network adapters and virtual switch in ESX host

  I'm new to VMware and am its implementation.  I got my training a few weeks ago, and now I'm configing my hosts.  I have 3 guests, each have 2 network cards.  There is a virtual switch that ESX creates when it is installed (vSwtich0).  The books said that it is advisable to delete the VM network port of virtual machine that is assigned to the value group default virtual switch and put it on another virtual switch so that you keep your management network separated from the network of the vm for performance and security.  If I do this, all my virtual machines will have to go to 1 NIC b/c I only have 2 NICs per host.  I thought that I have just to keep all my groups of ports on the default vSwitch0 and add my second NETWORK adapter so that I can take advantage of the Association of NICs for redundancy and load balancing.  However, I'm not sure on the performance and the security risks.  Do you have any ideas or advice?  I could also create two virtual switches and put my virtual machines on one which would have a NETWORK card dedicated and put my service and Kernal VM console on another virtual switch with a dedicated network card.  However, in this scenario, I have no fault tolerance or load balancing.  We are a small shop and we have about 10-15 VMs on each host.  I don't have access to b/c distributed switching we paid only for the company (not more).  Thank you.

  Hi and welcome to the forums,

  With 10-15 VMs per box and I guess that I would seriously consider adding two extra cards for each host in the production machines. You could then do something like:

  vSwitch0 - vmnic0, vmnic2, vmnic3 - Console of Service, VM LAN network

  vSwitch1 - vmnic1 - VMkernel

  That would give you redundancy and performance to access your hosts (SC) and also for all your virtual machines. The VMkernel would get a NETWORK card dedicated for vMotion and could be on a separate network. He didn't need redundancy really as if the NIC sank the only issue is that you cannot vmotion virtual machines. In this case you would just move one of the NIC workgroup through to those switches manually.

  If you only have 2 network cards, then I would say having a vSwitch with two attached network adapters and VLAN the VMkernel may be off. I want absolutely to the redundancy of having two cards together.

  Hope this helps,

  Dan

• Find a host physical NETWORK card IP address

  I am trying to find the IP addresses for my physics of the NETWORK adapter on each host.

  After http://communities.vmware.com/message/1332071 , I get MAC addresses, but I can't seem to get the IP addresses

  Karl

  ESX is used to map the vSwitches on your physical network adapters.

  You define consoles of Service or vmKernel (s) on the vSwitch (es).

  You have external access via the Service console COS.

  This is the IP address that you can access COS of the ESX Server.

  The natachasery have no Service Console (or VMKernel) IP addresses defined on them.

• Two network adapters physical separate networks

  Is it possible to implement two physical on a host running VMware Workstation Desktop cards, in a way where your host operating system uses one of them and one invited the other?  I need the host and guest on separate physical networks?  Example - my host OS is on our production network, but I want my guests to be on our test network.  Two physical production and test networks are completely separate and no physical connection between them.  Basically, my host Office would be multi-homed.

  Thank you

  Guest VM traffic is done only to the vnet to which you connect.  Therefore, if you configure NIC1 to be on by default in bridge network (vnet0) and NIC2 be bridged to vnet2 (for example), and then configure your guests with a vNIC connected to vnet2.  The prompt only "sees" everything that is connected to NIC2, because it is NOT connected to vnet0/NIC1.

  If you do not need host to go on the network at alltest traffic, you can disable the TCP protocol on the network to test NIC so no traffic host never goes that NIC just let VMWare bypass protocol enabled in order for the traffic of the virtual machine on this NIC

  However, if your host must have access to both networks, then imagine that virtual machines are running on another host on the network.  With your current physical machine with two network cards, ask you the same question: How can you guarantee that the traffic of the computer is done on the production network?  If you do not set a gateway for TCP/IP host on the NIC test network, so that traffic destined for this subnet test will go to this network adapter.  This means that two networks have different subnets, of course.  If the two networks are the same digital subnet (for example: both are 192.168.1.x) then you will have problems even in the absence of the virtual machines.

  The reason you do not set (and normally are not allowed to have two gateways) is if the traffic is destined for a subnet that your computer is not directly connected to, then your machine comes into contact with the bridge.  If you have two (or more) gateways, which is your machine contact?  Beyond simple dishes networks as in this example, you will probably need the assistance of an expert network.
