• Several physical network cards in WS8

  Hello!

  I have two physical NICs in my host with two different VLANS. I would like to connect a virtual machine to the first NETWORK card and an another VM the second network card.

  Is it possible?, I can choose "Bridged: directly connected to the physical network ', but how do I know which physical network?

  Hi Bartoooo welcome to communities,

  It is possible using the virtual network Editor. You must disable the automatic bypass and specify which physical NETWORK card to fill what VMNET adapter.

  This kb shows the use of the network virtual editor-in-Chief:

• Guest connection NIC mapped to the physical NETWORK adapter status

  I would like to know if it is possible to map a guest NIC to a physical host NIC so when a cable is physically disconnected from the host my guest knows.

  The new version of Workstation has this feature, but ESX did not yet.

• 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.

• Several physical NIC cards connected to vSwitch / Port Group

  Hello

  I have several physical NETWORK adapter on a host connected to a single vSwitch / port group, does this mean that the speed of the network is shared by all of the physical NIC, or I have to do something special to enable this feature?

  Please see attached .jpg

  Thanks in advance.

  If all of your network adapters is active in the nic teaming configuration, you must have a physical switch that supports the aggregation of links and you must configure it. The ESX itself does not have this kind of work.

  Actually is a bad idea to let all NICs connected without having to configure the nic teaming (1 active and others waiting for failover) or without going through the aggregation of links.

• 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).

• How to assign map physical NETWORK to the Virtual Machine.

  Hi all

  We have an obligation to assign the card physical NETWORK for VM, if anyone can confirm how can be achieved?

  Thanks in advance!

  Kind regards

  Varun Khatri

  You will need to configure the VM passthrough for the NETWORK card, and then assign it to your VM.

• 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.

• 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.

• Specify a physical NETWORK adapter to a virtual machine

  It is a fundamental issue, or it was in VMware Server 1.x, but in v2.x options may not be available.  Here's what I do:

  I have a physical host with 3 different network interface cards installed. I want to configure the vNIC on each of my 2 mV at one of the physical network cards, so they each have their own. In VMware server 1.x I would install a vmnet # for each NETWORK adapter and then configure each virtual computer to use one of the new vmnet I set everything up. VMware Server 2, I can still set up since both vnet (one for each NETWORK card), but when I go to change settings of NETWORK adapter in the virtual machine, I have three options (Bridged, host-only and NAT). Two of these two new vnets are "bridge", but I need to specify a fo the vnet jumpered for each.

  I know I must be missing something very simple, do not hesitate to point out my mistake. Thank you!

  What is your host operating system? If Windows, run the virtual network Editor (vmnetcfg.exe) announces the administrator, disable the automatic bypass and map each physical NIC to another VMNet adapter * in the tab "virtual host network address." If Linux, run /usr/bin/vmware-config.pl (it will take your virtual machines off / suspension) and choose to create more than one Bridged network when you are prompted, choosing different logical names and specitying eth0, eth1, eth2 or whatever they are called.

  Then in the virtual machine, they must appear in the drop-down list for the card that you have.

• How to access the virtual machines to different physical network?

  Hello

  I'm new to ESXi, can someone tell me how can I access virtual machines on the physical network existing in case I use different IP classes? Physics of the network by using the class C IPs and I assigned IPs to virtual machines of class A? If it is possible, then, what are the steps?

  In fact, I installed exchange 2010 VMs and also want to access the email accounts of physical network.

  Thank you.

  You mean there's no way in ESXi to configure the way so we can access the virtual machines to physical network? without third-party applications.

  Because it is impossible for the various networks IP connect without a router, you must have such a device. There is really no difference in that in a pure virtual or physical environment.

  You might think the ESXi host as a box with one or more servers (virtual) inside and one or more layer (virtual) two switches, just like a small server room. This means you will need to provide the same type of connectivity that you would have to a new server room with machines configured with addresses in a different IP network range.

• Two virtual machines share the same physical network adapter

  I have a virtual network adapter that I linked to a physical network adapter on my box where two virtual machines are running.

  I assigned two virtual machines to this vmnet adapter.

  On one I can ping other machines of physics on the same subnet as the physical computer, but the other VM can ping only other virtual machines.

  When I try to ping from one physical computer to this virtual machine I get the error message windows "ping transmission has failed. General failure. ».

  Is what I'm trying to are not not possible?

  First thing to do is to ensure the automatic bypass is enabled disabled in the VMnet virtual network editor your use to the bridge to.

  Second need to see the output of ipconfig/all on the Windows host and guests and or ifconfig on the Linux host and or guests.

  DO NOT copy and paste the output directly in the body of the response rather redirect the output of the commands in a text file and then archive (compress) files in a single zip archive and attach it to an answer.

  You can use the following example:

  Under Windows:

  ipconfig/all > "% USERPROFILE%\Desktop\host_ipconfig.txt".

  ipconfig/all > "%USERPROFILE%\Desktop\guest (n) _ipconfig.txt".

  Linux:

  ifconfig > ~/Desktop/host_ipconfig.txt

  ifconfig > ~/Desktop/guest (n) _ipconfig.txt

  Also include in the archive .zip .vmx and vmware*.log for two Virtual Machines configuration files.

• Which physical network my virtual machine port is connected to?

  Hi all

  We have several ESXs with classic vSwitches or dVswitches. All of them have several physical ports (classic NIC teaming configurations, all cards are active).  Different virtual machines are connected to these switches (a vnic by VM).

  Is there a way to identify which physical port every single VM is connected to? Of course, I have no access the physical switches...

  Thanks for your advice.

  You can this output to esxtop commands (press 'n') in vSphere 4. Thank you

• Assign a physical NETWORK adapter to the virtual machine

  Hey everybody,

  I did some research, but found answers to Linux and not Windows. Here's my situation:

  I'm running a physical machine with Dual Gigabit Lan and Windows 7 Pro. I would like to have all my virtual machines that I run under VmWare Workstation 6.5.3 using the 2nd physical NETWORK adapter on the mpotherboard. Is this possible? How do I? Thank you.

  Hello

  You can specify in the virtual network Editor (Edit toolbar option)
