• How can ping virtual machine on VMware Server external network?

  In the Vmware infrastructure products you can can be crazy from the outside through their individual networks connections, which is a good thing... lol

  How this is possible on VMware Server when guests use the VMnet8 network that uses NAT?

  In many scenarios, the use of bypass is prohibited due to the policy defined at the level of the external switch, but it is still necessary for the basic functionality of ping. Otherwise, how they would be able to know if a virtual machine is actually up to who answered the questionnaire on the network without entering actual connections to such hosts?

  You're right - that's how NAT works (whether via a service such as the VMware NAT service software or a hardware router/firewall NAT).  All computers behind the NAT server are hidden from the outside world (unless you map specific ports to the specific IP address of a computer)... they are so NOT to pings from the outside.

• VMware Server VM - network adapter disconnected - help needed please

  Hello world!

  I already install VMware Server running two virtual machines in test environments. Virtual computers running Windows XP Professional (Service Pack 2). VMware server itself is sitting on Windows Server 2003, which I have remote access.

  The plan is to let the virtual machines running continuously and access them directly on a Remote Desktop Protocol. It was working fine until we had an incident with Windows Server 2003.

  The incident was that we decided to upgrade to Service Pack 2 on the server. When we restarted the server, we found that the IP Configs were changed. NIC 1 didn't have any parameters calibrated but NIC 2 made. We removed NIC 1 and then reconfigured to run 2 NIC NIC 1.

  The server now works fine and we can remotely access, but the virtual machines have lost their configurations. When I run it says that the network adapter is disconnected. I kept them and adding new hardware, selected network adapter and connect at startup. But whenever I run a virtual machine, it says that the network adapter is disconnected.

  Anyone know how to fix this? any help would be greatly appreciated.

  Thank you

• 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".

• VLAN again added, problems detected on guests during the detection of new network configuration

  Hi all

  I started facing a strange problem trying to use a new VLAN configured in my vCenter environment...

  Basically, my system 'fight' to identify the new network label (VLAN) configured, leaving systems disconnected from the local network.

  This condition disappears only when I change the VM touched, assign a label of different network (VLAN), apply the changes and restart the process by configuring the new VLAN return.

  We will use an example to explain better:

  • I have a named Windows Server/Workstation VM: VM1
  • I have 2 VLANS configured in vCenter: VLAN50 and VLAN70

  VM1 is sitting on the VLAN50 and has the static IP address configured.

  I start the migration of the machine to a VLAN different, by editing the network settings of the operating system (IP, MASK, GW, DNS entries...) and replace the label of VM1 VLAN70 network.

  At this point, the machine NIC shows as if it could not connect to what in the network, although it is configured accordingly in order to communicate in the new subnet.

  I have change the VM again and change the label of a network VLAN different from VLAN70, click OK. Immediately, I change VM settings to assign in return the VLAN70.

  After that, the operating system recognizes the network successfully and starts working as expected...

  All of my virtual machines use VMXNET3 adapter and my version of vCenter is v5.5 build #2646482

  No idea what might happen?

  Concerning

  We found the problem...

  It was not associated with VMware, but a network configuration problem: (ESXi connected to two switches, one of them with the VLAN configured correctly and the other does not...).

  Thanks for the help

• VMware Server 2.0 CIFS data store bug?

  I posted this problem a few weeks ago, but I still can't solve, then I write it again with new information on the problem. I think it could be a bug in VMware Serever but I am not certain about it.

  I use VMware server 2.0.2 (b203138) with a Windows 7 Ultimate x 86 as vmware server host and configuration of the NAS data store. The data store hosts all virtual machines, including the ones configuration files, and it's a shared folder located in a Windows Server 2008 Enterprise x 86 SP2. The network mode working group, not in mode active directory.

  Symptoms of the problem:

  • If you stop or restart the host server, when it is once again the CFS data store is unusable and VMS are inaccessible, even if all of them were arrested at the time of the restart.

  • The option to update the data store does not solve anything.

  • If the NAS data store is deleted and recreated from scratch, the machines are still not accessible. It is also necessary to remove and re-add the VMs.

  • If you only reboot the VMware services then you lose not the NAS data store or virtual machines.

  • If you only reboot the NAS then also you don't waste either the data store, or virtual machines, although they were in operation when you rebooted the NAS; the same happens if you stop communication network between the host server and the NAS.

  • A delay in starting services VMware does not solve anything.

  • I tried the start VMware services in manual mode, to be sure that there is full access to the NAS before starting the service, but VMware is still losing the NAS data store and virtual machines, this isn't a problem with permissions to access the network or network connectivity.

  Any help would be much appreciated. Thank you.

  This applies to all the BONES that I know. VMWare server 2.x just keeps the security attributes for authenticated access to CIFS shares underlying network based data stores you set.

  I see some information that it's actually worked in server 1.x version, but I can only confirm.

  I don't know if it is a bug or by design since this behavior has persisted through several versions 2.x, it can be design to users of reader for commercial versions.

  Good luck

• Configure a virtual firewall VMWare Server 2

  Hello

  I'm configuring a virtual machine which will act as a firewall ISA Server. The machine is now running on a physical machine. I used VMWare Converter to change it to a virtual machine. However, I am unable to set up the configuration of the network. For after this post: http://www.cs.drexel.edu/~vp/VirtualFirewall/ I should create a network invited only to the internal network and a connection open in the external network.

  This last little is where the problems come. The external network has a mask of 255.255.255.252 network, so I have only 2 IP address in the network: 1 the host machine and the other is for the default gateway. Implementation of bridged networks is therefore not an option. I tried setting up guest network only on the external interface, but then VMWare server is unbootable. (The DCHP server on/dev/vmet1 does not start).

  Operation of the machine I have RHEL 5 host OS. It has 2 physical NIC, 1 connected to the internal network and externally 1. Is there perhaps a way to Server2 VM I can ask the network adapter connected to the external network exclusively for this virtual machine? Or is there maybe a better way to implement?

  Any help will be greatly appreciated.

  You can use fill or NAT if you need to communicate outside the host. You cannot configure 'host-only' on the physical map, because this isn't 'host-only' more.

  If you cannot use open due to lack of IP addresses (as a virtual bridged interface needs its own IP address) you can use NAT. In this case, the host acts as a NAT proxy to the client (your firewall). To the outside world only the IP address of the will be visible. The customer will receive an IP address from the VMnet8 virtual network (if you are using DHCP, you can use a static IP address in the range of addresses network IP VMnet8).

  But you must forward packets to the port prompt if there is no communication initiated from the outside at the prompt.

• Can how fast I get a virtual network adapter on a computer server VMware vmware tools installed w/o?

  Hello

  I use a custom Linux VM on a Linux VMware Server host. That my Linux VM is on measurement, I don't want to install VMware tools on my virtual machine. My question is without VMware tools installed on my virtual machine, is it possible for my virtual machine to connect at gigabit speeds. My server host has a gigabit network connection.

  Thank you

  Varun

  without vmware-tools, make sure you that you use the E1000 nic in the comments and not the obsolete AMD

  Check with the vmx file and make sure that you have

  ethernet0.virtualDev = "e1000".

• 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.

• How to configure server DHCP of VMware Server 2 to play nice on my network?

  I have 8 physical systems running on a network.

  A system running VMware Server 2 on it.

  Server DHCP of Server2 provides virtual machines with IPs on the 192.168.106 network and they all work fine, all virtual machines find each other and physical systems too.

  My wireless router is a DHCP server which provides boxes of physical IPs on the 192.168.2 network and works very well between physical systems.

  The problem occurs when a physical systems trying to access a virtual machine.

  All virtual machines are set to run in NAT mode, I tried no succcess one either bridged mode.

  The VMs system static IPs on the 192.168.2 network also fails miserably as all of my attempts to set masks subnet on all systems.

  I think I need to 'fix' the VMware Server 2 DHCP server, but have not yet find data on this topic, and I'm not sure that if I do this will help.

  Any solution here would be FANTASTIC.

  Past esxi was not really going to do this I feel even if you have not installed - it is really intended for high-end package rather than SATA based servers while sort will work on some.

  Their reason to exceed the NAT is filled? If you want to that virtual machines at all simply appear as regular machines on your existing subnet then packed is the easiest way to go because virtual machines must be able to obtain their IP addresses of your router, as well as physical boxes. DHCP server 2.0 is just for the NAT and host only networking that it manages-for machines virtual NAT, you must configure the port forwarding on the host server 2.0 for all the traffic you want to enter in the virtual machines from the outside since by default, all incoming ports are blocked, appropriately with NAT, see Chapter 11 of the user guide - http://www.vmware.com/pdf/vmserver2.pdf

  So, if you want to go to bridge, we need to understand why this does not work as it should be "out of the box" as long as there is no any firewall host or other security software, for example the clients VPN, which will block traffic. What is the host operating system? Please post ipconfig/all or ifconfig - an output of the host and the guest. How have you configured in bridge network - using the default settings? Virtual machines get an IP address from your router?

• Not available in the configuration of the adapter VMNet8 virtual network

  Hi all

  I have HAD the following config:

  Virtual Server 2 on a machine with a physical NIC XP

  Two comments machines two Ent W2K3 running.

  IP address 192.168.1.1 and 2.1 default gateway of 192.168.1.5

  Both machines network cards configured to use VMNET8. VMNET 8 configured through the virtual network with IP 192.168.1.5 Editor

  The virtual card configured VMNET8 with 192.168.1.5 address in the host network configuration and the default gateway set as 192.168.0.254, that is the address of the gateway for my network home.

  With this config, I have had my two virtual on the same network and "Native" computers to the internet via my home network.

  Problem now is that somehow my journey becomes stripped on the host. The NIC VMNET8 achieved somehow a metric is lower than the physical host adapter. No problem when accessing the net from virtual methods, but when you try to access the net from the host machine, it attempts to route the internet traffic on the virtual interface on VMNET8 and of course fails.

  In addition, the possibility to connect the virtual machines to VMNET8 is not an option in NIC on each virtual machine settings more. I only have NAT, connected by a bridge and host-only.

  I spent some time on the issue without success so I uninstalled VMware and removed two virtual machines. After you have reinstalled, I am always presented with the same two questions.

  Does anyone have an suggestions?

  Kind regards

  Hamish.

  Welcome to the forums!

  I would say to keep the values by default as long as you have a good reason to change.

  Configure:

  I guess 192.168.1.0/24 is your address for VMnet8 network!

  The adapter VMnet8 host to:

  no gateway 192.168.1.1 by default, it is not necessary here.

  Comments:

  Either DHCP (served by the DHCP of VMware Server) or fixed IP 192.168.1. < starting="" with="" 10=""> , DNS, default gateway: 192.168.1.2
  If you use the VMware DHCP server control if 192.168.1.0/24 is configured as network VMnet8 address.

  Do not connect to the vNIC to VMnet8, choose 'NAT', which is VMnet8.

  Okay, that means, is not in your server room.

  Your computer has several available ethernet network interfaces: eth0, eth0: 0,

  eth0: 1, eth0:2, eth0:3. Which do you want to bridge vmnet0?

  Your server has only one physical ethernet interface. But there are multiple ip addresses configured on it. If you want to know, how it works and how it is configured, you can read this page.

  You need to reconfigure your network VMware Server 2 to fill the other or several networks. VMware Server documentation is explained on p. 222 and following. In fact, for linux, it is page 229 and includes 'ifconfig' to know what special device (eth0: 0...) what IP address, then run ' vmware - config.pl ' is used to assign the new configuration. But please read the documentation for more details.

• configuration network on VMWare server 2

  Hello

  I installed Vmware server 2 on my server (WIN2k3 with nic 2s because my server have a role of routing). A NIC is set up for INTERNET and other NIC is set to INTRNET.

  the configuration of my INTRANET is on class C IP:192.168.99.XX, SM: 255.255.255.0. I create a virtual Instalation with UBUNTU 8.10 Server... I installed UBUNTU with no problem and without error, but without internet access because I don't know what ip and network configurations I should do on virtual NIC (Vmnet1 and Vmnet8) and which configurations should I do ifconfig on UBUNTU (IP, SM, gateway, DNS)

  can someone help me?

  Thank you.

  Depends on...

  I'll explain what these networks and you can find what you need:

  1 bridged (VMnet0)

  If the virtual NIC (vNIC) is fulfilled, the guest takes part like any other host on the network. It needs its own IP address corresponding to the IP network to which it is filled.

  2 host-only (VMnet1)

  It is a network isolated between the host and the guests. No outside communication.

  3 NAT (VMnet8)

  When you use this type the host acts as a proxy routing with address masquerading. This means that all packets send by the client appears to come from the host to the outside world. You can hide your comments like that.

  What physical adapters is used to fill can be configured. The default value is one automatically chosen NIC jumpered to VMnet0. You can create a custom network (say VMnet2) and he a teddy bear additional bridge.

  Networks VMnet1 and VMnet8 can be served by the DHCP of VMware Server, so if you use this type of vNIC and you configure the IP address in the guest to use DHCP, you're fine.

  Don't forget to use a firewall at least on the vNIC which can face outside if you use bridged or NAT to connect to the Internet!

• To hardware Version 7 computers virtual in VMWare Server 2.0.2 ESXi 5

  Hello world

  Taking his retirement from 2 host vmware server computers.  They run Server 2008 64 with VMWare server 2.0.2.  Each host has 3 VMs Windows, 6 in total, all configured with Hardware Version 7

  The plan is to set up a new host running ESXi 5.  Install, configure and ready for deployment.  After you have configured the data stores, I want to spend my VMs the 2 old servers a new box of ESXi 5.

  I'll copy all virtual machines from the old servers to individual folders on my Windows 7 Desktop and use the vSphere client to load the virtual machines on new data stores.

  I read that ESXi 5 can read Version 7 VMs.  Does this mean I can use the virtual machine as is, or still need to convert the hard?  I would like to convert them before their download?  I'm a little gray in this area...

  Can you get it someone more experienced please let me know the step by step... or a link to a good "how to" I would really appreciate it.

  Thank you

  There is nothing for you. VMware Converter takes care of this. It will not only increase the size of the disc, but also the size of the partition.

• Generate url for virtual machine installed on vmware server console programmatically

  Hello

  I want to generate URLs for machine vmware console located on vmware server. Are there examples of available in c# code? Any help will be really good.

  Thank you.

  Hello

  There are already several posts/Articles on this subject. What works for ESX should work for VMware Server. The misfortune is that it should be avoided for several reasons:

  (1) there are only a limited number of "consoles" allowed for a given server of VMware

  (2) RDP/VNC is a tool much better for this as there are no such limits

  (3) the security of this method is somewhat limited

  (4) more than one user can access the same VM without protection of the user (essentially a struggle for control)

  So in general, it is best to RDP/VNC in the virtual machine is to use the console.
