• ESXi VM virtual network question

  I have two virtual machines on ESXi

  1 Sophos UTM (assigned 'NET' and 'LAN' physical network interface)

  2 Ubuntu server (not assigned any physical network interface still)

  If I assign a new physical network interface 'LAN2"Sophos and also assign another new interface for ubuntu server network, then they will be connected through a physical cable, ubuntu server will be under sophos. However, I want to know is - it possible to do it with virtual on ESXi because that I have enough physical network interface to which their responsibilities.

  Thank you.

  If I understand correctly, you need a direct link between these two VMs running on the same host ESXi!

  In this case you don't need no physical connection. Simply create a new vSwitch without any rising (vmnic) and connect two virtual machines to a portgroup VM on this vSwitch.

• 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.

• Networking question in VMware Workstation / nested ESXi network configuration problem

  Hi guys,.

  I am trying to set up a virtual lab, I setup a domain, a vcenter server and up to 1 ESXi host controller.

  I am really struggling with the network aspect in establishing a vmnic for storing shared, please see the attached screenshots and a few questions:

  1. Is a vmnic a real network map? or vmnic correspond to "network adapters" that you put in place since the setting of your virtual machine?

  I followed a tutorial and implement 3 NICs on the ESXi host, in Bridge mode, I tried this in my configuration of vmworkstation and I lose the connection to my server vcenter to the ESXi host.

  See screenshot attached to how I configured my ESXi host, screenshot is called 'screenshot2esxihost network', I run got each of the maps defined on NAT network.

  

  See also the screenshot of how I have my configuration of network settings in my VMWare Workstation, screenshot is called "screenshot1. the tutorial does not show how it has its editor of the virtual network configuration, but it puts its ESXi host NICs in BRIDGED mode, and I'm guessing that you can set this time within the virtual network adapter. If someone could tell me what changes should I make in there and on the network cards in my ESXi host, which would be really useful.

  

  My domain controller, server ESXi hosts and vcenter are currently on the 192.168.86 range, which currently stood at NAT

  See also a screenshot from the vsphere client - I don't see a vmnic "vmnic0", my goal is to be able to add a "vmnic2" for a separate storage network.

  

  any help would be received with gratitude, I VCP510 review at the end of the month and really hope to be able to get my lab setup as soon as possible.

  The vmnic is the rising 'physical' of an ESXi host. So with the 3 network cards that you configured for the host in VMware Workstation you will see under "Network adapters" and you can use them to vSwitches in the section "network".

• How to set a specific MAC address for a virtual NETWORK adapter in ESXi 4.1?

  I would like to move a virtual machine to another server ESXi, but I saw every time I use the converter, it changes the MAC of the virtual network interface! Also if I copy the virtual machine to a vmware 2.0 server the same thing happens. Is it possible to keep the same address in another computer and turn off the virtual machine from the first computer source to avoid conflicts of mac?

  Thank you.

  Using the converter, you'll always end up with a different MAC address. If you just want to "pass" the virtual machine, you can use utilities like of Veeam FastSCP.

  Another option is to set up a MAC address in the network settings of the virtual machine. After conversion, you can reset the MAC address to the value of "old."

  For some hosted VMware products (such as Workstation and Server maybe player) there's a vmx ethernetX.checkMACAddress = "FALSE" setting that allows you to set any MAC address you want to. For more information, see http://sanbarrow.com/vmx/vmx-network-advanced.html.

• 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.

• The ESXi Server network configuration

  Hello

  This is a pretty silly question for most of you, but I don't have any experience on ESXi.

  If an EXSi server has 4 installed physical network cards, this means that it can only subnets different hosts 4? they are more than 4 subnets to be hosted, one or more servers need to be purchased ESXi?

  Thank you

  Hey Roywang,

  You can have as many subnets you want as long as they are all set on your physics of switching.  For example:

  VLAN 100 - 24 10.1.1.X

  VLAN 200 - 10.1.2.X 24

  VLAN 300 - 10.1.3.X 24

  VLAN 400 - 10.1.4.X 24

  VLAN 500 - 10.1.5.X 24

  VLAN 600 - 10.1.6.X 24

  VLAN 700 - 10.1.7.X 24

  Now, with these VIRTUAL networks, you can cut your vSwitch like this upward:

  vSwitch0

  PortGroup - management - VLAN100 - 10.1.1.5/24 active VMNIC0, VMNIC1 ensures

  VMotion PortGroup - - VLAN 200 - 10.1.2.5/24 VMNIC1 active, VMNIC0 ensures

  PortGroup - VM Network - VLAN 300 - VMNIC0, VMNIC1 Active 10.1.3.5/24, active

  PortGroup - VM network WebServer - VLAn 400 - VMNIC0, VMNIC1 Active 10.1.4.5/24, Active

  PortGroup - VM Network Backup - VLAN 500 - 10.1.5.5/24 VMNIC0, Active, Active VMNIC1

  vSwitch1

  Port - iSCSI1 - unused VMNIC2 VMNIC3 Active 10.1.6.5/24 Group

  Port - iSCSI2 - 10.1.7.5/24 VMNIC3 VMNIC2 Active unused group

  What is happening is essentially in your vSwitch each port group gets a tag VLAN, then on your physical switches where the nics connect tag, what is needed, and the switch will forward the packets accordingly.  For example, the ports that vmnic0, vmnic1 plug on the physical switch you would tag for VLAN 100,200,300,400,500 like all these networks can land on each network card.  You will also need these trunks in trunk for this mode.

  If you have any questions please let us know.

• Establishment of a virtual network

  Hi all

  Sorry if this question is asked a million times, but as a beginner to ESXi, I'm having some trouble to configure my virtual network. The pointers in the right direction or links to the guides of initiation would be accepted with gratitude.

  Basically, at the moment, I have Win 2 K 8 R2 x 64 and Win 7 x 64 VMs put in place on my server ESXi. The 2 k 8 is a domain on my existing external domain controller. It is also a DHCP and DNS server (I'm going to RRAS later). It has 2 vNIC. The first card (wan) receives an ip address on my broadband router and is therefore very well (I'll deal with public IP addresses later). The second is the interface lan / vlan and is configured with a static IP, 192.168.20.5, which is the address of the dns server and the subnet ip (192.168.20.x) served by DHCP. Ideally, I would like to connect to a physical NETWORK card for the internal network physical, but also a virtual internal network that vms in the same domain can connect to.

  The vm Win7 has a vNIC and does not have an address at the present time. It is configured on VM2, as is the internal vNIC to the domain controller.

  At a later date, I also intend to add a second domain separate and DC with the same configuration (we run two businesses from the same site). There may be any connection between the two. The physical aspect is pretty straighforward. It would simply be a matter of physical extra network adapters and duplicate the configuration for the first area?

  I hope this makes sense.

  Thanks in advance.

  The second network has no network management...

  Network management is used to manage host ESXi itself and has nothing to do with the Virtual Machine networks, so there is no need to install a network of management on each vSwitch.

  ... and I don't have internet on the virtual machine windows 7.

  How could you, without uplink. It is basically the same as for a physical network. If a PC is connected to a switch, and there is no connection to the Internet (for example, a router), you will have the chance to work online.

  It will appear and I could binds to Network 2 VM when it is connected so that the server can serve both physical customers?

  Yes, it should work.

  I need bridging the connections in some way to allow the customer to win 7 access internet connection of the VM network 1.

  What is the purpose of separate areas if you want now fill the networks? What you can do is use a firewall (for example, pfSense), configure a separate vSwitch for each domain (without uplinks) and configure the firewall to connect to each vSwitch 'domain' as well as with the uplink to allow Internet traffic to the different areas but block direct traffic between them.

• Creating an ESXi Virtual Lab for testing and learning purpose

  I am new in this VMware technology. I have a few questions here. I am trying to set up a virtual test on my laptop environment. Is this possible?

  The laptop has processor i7, 12 GB memory and 2 x 500 GB HARD drive. I will use the second 500 GB to Openfiler iSCSI connection.

  Here are the questions.

  1. the laptop has only one LAN port, but I need to define HA and FT on it. Can I just add more virtual cards on ESXi hosts?

  2 workstation 7 by default has VMnet0, VMnet1 and VMnet8. Can I use them for ESXi hosts also or they should not be used?

  3. what options should I assign these virtual network adapters (NAT, host-only or custom)?

  When you create your host ESX (i) inside Workstation I would use just filled to the right network to start. Keep it simple to start. Set up as a virtual Workstation machine openfiler.

• Ea6400: virtual network

  Once more a question and then I think my router is perfect

  I have some IP cameras on my WiFi network.

  When I want to see them out I had to do a virtual network on my old router.

  When I go to Conectifity > Advanced routing

  I see that NAT and RIP

  Static routing is not the same as in the old router.

  But how I do on this one?

  Thanks for the thought.

  Hi taxikemperman. I agree with what proposes FurryNutz. You need to forward ports to access the cameras remotely. You can also register for any server domain so that you can easily access the camera outside your network. I would also say that you set a static IP address on each of the wireless camera, so you can correctly determine which cameras, you are trying to access.

• vWorkspace 8.0 | HyperV 2012 R2 | &lt; Unspecified &gt; virtual network name

  At a customer's, we went just all HyperV server to HyperV 2012R2.

  Now, we have a problem that the "said virtual network name '.

  Is this a known issue?

  Import does not work in my case.

  To work around the problem we have already defined the network name in the settings manually, but it's always a strange question.

• VIRTUAL network interface routed, is this possible?

  I have a 3560 which hangs a 6509. The next SVI s direct on the 3560:

  192.168.181.1(VLAN 192.168.180.1 (VLAN 180), 181), 192.168.182.1 (VLAN 182), 192.168.183.1 (VLAN 183), 192.168.184.1 (VLAN 183).

  I have the following routed interfaces between the 6509 (192.168.0.17/32 and the 3506 (192.168.0.18/32).)  Currently, I use a gateway of last resort to get the traffic off of the switch and a static route to send traffic to these IVS.

  I have a few VLANS that I use for vSpere and traffic of ESXI (239 (vMotion), 243 (Fault Tolerance), (250, iSCSIStorage), 254, ESXi), 255 network management).

  Is it possible to send these VIRTUAL networks through the routed interface?

  I have a few guests of ESXi requiring 254, 239 and 243 for vSphere features.

  Short answer is with the equipment you have not you cannot.

  What you can do is-

  (1) create a new vlan purely for the link between the switches and create an IVR for this vlan on each switch.

  The IPS for the Lass will be the IP addresses that you currently have on routed ports.

  (2) the link is a link to trunk and leave the new vlan and a VLAN that you want to extend for example. between the switches.

  The important thing here is to allow only on the trunk link the new vlan, and the VLAN that you extend.

  (3) the VLAN that you not extend ie. VLAN 180, 181 etc are not allowed on the trunk link and therefore will be always sent between switches across the new vlan because the Lass for this vlan have the IPs had initially allocated you to the ports of L3.

• 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.

  on a 64-bit host export settings like this
  "C:\Program Files (x 86) \VMware\VMware" _-_ export f:\ws-networkbackup.txt
  Note the syntax:
  _ should be a space
  -is not a unique dashboard but 2 x less

  You can import this backup again if you replace import export.

• Configuration problem for ESXi lab network settings

  Hello

  I'm setting up a personal lab on a laptop. I created 2 virtual ESXi servers with VMware Workstation.
  Creating virtual machines ESXi, I chose the NAT option for networking:

  

  I then tried setting up two interfaces vmkernel on vSwitch0 by default for each ESXi server, select obtain IP settings automatically everywhere, as follows:

  ESXi1

  

  ESXi2

  

  I have created 4 virtual network adapters for each host and add them as active adapters to the switches.

  The problem... or ESXi pings host each other!

  What I am doing wrong?

  What are the pings, I launched of ESXi1

  ~ # ping 192.168.138.136

  PING 192.168.138.136 (192.168.138.136): 56 data bytes

  -192.168.138.136 - ping statistics

  3 packets transmitted, 0 packets received, 100% packet loss

  ~ # ping 192.168.138.137

  PING 192.168.138.137 (192.168.138.137): 56 data bytes

  -192.168.138.137 - ping statistics

  3 packets transmitted, 0 packets received, 100% packet loss

  That's what I thought. I suggest that you wipe the cloned ESXi host, create a new virtual machine and install again. You can also consider using a separate subnet for the vMotion network to avoid problems.

• VMware networking question

  Hi people out there. First time poster in the hope of getting some ideas. Here's some information and what I'm trying to accomplish.

  So I set up a VMware environment for me and a friend to me so that we can play with ESXi and virtual systems and configurations.

  My home system has 1.5 to storage and 32 GB of memory, so I decided to use my system to be the host.

  With the help of VMware Workstation 9, I created a virtual machine with 16 GB of RAM and 1 TB of storage to use for our game environment. I installed the ESXi host on this virtual machine (Yes a VM will be my virtual machine host).

  -J' have the host connected to VMware Network Adapter VMnet8 from my PC to give it a different IP subnet separate from my primary home network on 192.168.65.x

  -J' have a Terminal Server running Windows Server 2008 R2 as my first virtual machine with 2 network cards virtual

  -J' have a second vSwitch systems to connect to my home network primary 192.168.1.x. whose purpose is specifically to the server terminal server, so I can route RDP on the internet for the TS.

  -I don't want my virtual systems with access to the main network (beyond the Terminal Server computer) and I don't want ALL of the virtual machines to have internet access on a network.

  -My level of router, I have internet blocks from the host and IP address on the second card of the server terminal server. Then I'm OK.

  Here's my problem. Power of the internet on the TS works that until I got disabling the adapter connected to the 192.168.1.x. I can always get internet access through the 192.168.65.x of my main PC adapter. All my other virtual machines will be connected to the reseau.65 so they are not using my primary network traffic and I don't want them having access to my internet. I want to just beyond the server terminal server itself, being separated from my home network and that you have access to its own internal virtual reseau.65 and nothing outside of it. I know individually, I can specify an IP address and just put the default gateway to something like 0.0.0.0 and which effectively blocks this system to have internet, but I don't want to have to rely on set up this configuration or pressing the friend who will use to access this virtual network to do this in any new VM he created RDP. I want to do in the world in terms of network, if I can.

  Any thoughts are appreciated. If I failed to point out anything please let me know and I'll try to explain.

  Thank you!

  Welcome to the community,

  If I understand your requirement, all that you need to do is to open the virtual network Editor, create a new 'Host-Only' virtual network adapter (uncheck the box "connect an adapter to the virtual host in the network) and use this new host only instead of NAT network adapter.
