Question on networks of Virtual Machine

• Networking between virtual machines on different hosts

  Hello

  I need some advice on the basic approach to networking between virtual machines, each running on a different host machine.

  Consider the following configuration:

  I have a few processes that are running in a Machine virtual Ubuntu. Call this guest1.  I guest1 race inside a real computer running Windows XP SP3 and VMware Workstation 7.x; Call this host 1.

  I have a copy of this virtual machine that I put on another machine.  Call this Guest2.  I have Guest2 running on a separate physical computer, also runs Windows XP SP3 and VMware Workstation 7.x; Call this host 2.

  Now, I would like to guest1 and 2 comments to make networking with eachother.  I wish they were able to ping, SSH, etc., among others.

  This is where I am stuck. I tried setting the virtual machines to use the bridged network mode.  I tried to connect my router on each computer and manually assigning IP addresses to each host and each virtual computer.  When I do this, guest1 can Host1 and Host2 ping, but cannot ping Guest2 and vice versa.

  What is the right way to do this kind of network?  This seems like an obvious application, if you want to perform simulations on multiple virtual machines residing on different computers on the network.

  I apologize if this is the answer elsewhere, I had to dig and was not able to find the solution.

  Thanks in advance!

  Guests must be on the same subnet, like 'real' hardware machines.

  1 when you copied the VM and then started, what did answer you the question of copy/move? (this determines if a new MAC address is applied)

  2 view each guest and ' ipconfig/all' results 'ifconfig - a' by the hosts.

• "this host is not no matter what networks of virtual machine, or you don't have the permission to access ' ESXi V4

  I'm sure I'll be stupid on this one, but what does do to ensure that networks of virtual machine?  I get this message when I look at network/properties of a VM adapter 1.

  When the virtual computer runs, my network card think the cable is disconnected.

  I went to the host properties and of course there is a 'Virtual Machine port group"and a"VMKernel Port", both connected to my physical card.

  I don't see anything obvious on the network are disabled or anything like that.

  Please give me a hint?  Virtual machines to run it, but without any network connectivity.

  Thank you

  I had this on the virtual machines that I moved from VMware Server 2.0. I found that there is no entry for the "ethernet0.networkName" in the .vmx files Server 2 (and probably Workstation) do not seem to care and connect ethernet0 to the first configured network. ESXi 4 all confused. So for me, the solution was to add

  ethernet0.networkName = 'Hand Lan'

  for each file .vmx before adding them for ESX. If you have already added the machine, you will need to remove it before you edit the .vmx file.

• Monitoring and network of virtual machine failure alert

  I'm trying to set up an email alert when one of our VMS lose network connectivity. I'll try the following settings, but I don't receive any alerts when I kill the network connection.

  • Alarm type: Virtual Machine
    • Monitor for specific events occurring on this suybject...
  • Trigger: VM No. network access
  • Status: alert

  I tried the same settings with a different event (for example on and power off the power) and I get an alert message each time. But with network access I get nothing. For the test, I have reset the INVESTIGATION period (so there is no network activity), I disabled the NETWORK card and I tried to disable the NETWORK adapter in the settings of VMware.

  Nothing alert? Essentially, I jut want an email when any of my virtual machines happen to lose access to the Internet for a reason any.

  Thanks for any help.

  Another note: I also tried to use different drivers Ethernet, with no luck.

  Decided to use only ONE Veeam.  Their free version offers sufficient data and monitoring.  Seems that monitoring network is a deficit of VMware.

• Removal of the network of virtual machines powered cards

  I wanted to remove the network adapters on multiple virtual machines, so I thought that he would do a simple script:

  Get-NetworkAdapter -vm test* | ?{$_.NetworkName -like "dummy"} |Remove-NetworkAdapter
  

  But this results only by mistake because the virtual machine is running:

  Remove-NetworkAdapter: 2013-08-13 15:58:48 NetworkAdapter Remove the

  Virtual MACHINE must be in the following State: PoweredOff.

  Is it possible to get around this problem?

  Given that this is possible through the vSphere Client he gave me the chance to try Onyx. Here is the result of the Onyx:

  $spec = New-Object VMware.Vim.VirtualMachineConfigSpec
  $spec.changeVersion = "2013-08-14T07:04:15.86208Z"
  $spec.deviceChange = New-Object VMware.Vim.VirtualDeviceConfigSpec[] (1)
  $spec.deviceChange[0] = New-Object VMware.Vim.VirtualDeviceConfigSpec
  $spec.deviceChange[0].operation = "remove"
  $spec.deviceChange[0].device = New-Object VMware.Vim.VirtualVmxnet3
  $spec.deviceChange[0].device.key = 4000
  $spec.deviceChange[0].device.deviceInfo = New-Object VMware.Vim.Description
  $spec.deviceChange[0].device.deviceInfo.label = "Network adapter 1"
  $spec.deviceChange[0].device.deviceInfo.summary = "dummy"
  $spec.deviceChange[0].device.backing = New-Object VMware.Vim.VirtualEthernetCardNetworkBackingInfo
  $spec.deviceChange[0].device.backing.deviceName = "dummy"
  $spec.deviceChange[0].device.backing.useAutoDetect = $false
  $spec.deviceChange[0].device.backing.inPassthroughMode = $false
  $spec.deviceChange[0].device.connectable = New-Object VMware.Vim.VirtualDeviceConnectInfo
  $spec.deviceChange[0].device.connectable.startConnected = $true
  $spec.deviceChange[0].device.connectable.allowGuestControl = $false
  $spec.deviceChange[0].device.connectable.connected = $true
  $spec.deviceChange[0].device.connectable.status = "ok"
  $spec.deviceChange[0].device.controllerKey = 100
  $spec.deviceChange[0].device.unitNumber = 7
  $spec.deviceChange[0].device.addressType = "assigned"
  $spec.deviceChange[0].device.macAddress = "00:50:56:8f:74:52"
  $spec.deviceChange[0].device.wakeOnLanEnabled = $false
  
  $_this = Get-View -Id 'VirtualMachine-vm-646'
  $_this.ReconfigVM_Task($spec)
  

  After the stripping it down a bit I ended up with:

  $spec = New-Object VMware.Vim.VirtualMachineConfigSpec
  $spec.deviceChange = New-Object VMware.Vim.VirtualDeviceConfigSpec[] (1)
  $spec.deviceChange[0] = New-Object VMware.Vim.VirtualDeviceConfigSpec
  $spec.deviceChange[0].operation = "remove"
  $spec.deviceChange[0].device = New-Object VMware.Vim.VirtualVmxnet3
  $spec.deviceChange[0].device.key = 4000
  $spec.deviceChange[0].device.deviceInfo = New-Object VMware.Vim.Description
  $spec.deviceChange[0].device.deviceInfo.label = "Network adapter 1"
  $spec.deviceChange[0].device.deviceInfo.summary = "dummy"
  
  $_this = Get-View -Id 'VirtualMachine-vm-646'
  $_this.ReconfigVM_Task($spec)
  

  Run this doesn't give any errors, but are still all NICs.

  Is there a way to easy or better for this script?

  You must create an entry in the DeviceChange property by the device you wish to reconfigure.

  Try something like this

  $VMs = Get-VM test*
  
  $NICs = 1..6 | %{"Network Adapter $_"}$i = 0
  
  foreach($VM in $VMs){  $spec = New-Object VMware.Vim.VirtualMachineConfigSpec  $Adapters = Get-NetworkAdapter -VM $VM|?{$_.NetworkName -like "dummy"}  foreach($Adapter in $Adapters){    if($NICs -contains $Adapter){      $devSpec = New-Object VMware.Vim.VirtualDeviceConfigSpec      $devSpec.operation = "remove"      $devSpec.device += $Adapter.ExtensionData      $spec.deviceChange += $devSpec    }  }  $VM.ExtensionData.ReconfigVM_Task($spec)}
  

• How to install VMplayer 3 network for virtual machines to comminicate with each other?

  People,

  Hello. I use VMPlayer 3.

  SE host: Windows 7
  Comments to: Windows XP and Oracle Linux 5

  I need to set up the network and activate Windows XP communicate with Oracle Linux 5.

  I followed this tutorial http://www.vmware.com/support/ws5/doc/ws_devices_serial_2vms.html to configure 2 virtual machines in Windows 7 host machine.

  I tried to test 2 virtual machines in the way as below:

  In Linux, [user@localhost ~] $ping WindowsXP_HostName
  Release: Unknown host WindowsXP_HostName

  
  At the Windows XP command prompt:
  C:\ping localhost.localdomain
  Its release: ping localhost 127.0.0.1 with 32 bytes of data...
  Reply from 127.0.0.1: bytes = 32 time = 2ms TTL = 128

  
  He meets a few times and then disconnected by itself. It seems that Windows XP is ping itself and not Linux server. The host name of the Linux server is 'localhost' as well. It is a kind of confusion for me.

  
  From the information above, we can see that 2 VMs cannot connect between them.

  Can any folk provides a tutorial or example or case study to set VMPlayer 3 allowing 2 virtual machines communicate with each other by step?

  Very grateful in advance.

  In the guest machine, all I see is click on VMplayer-> VM-> settings-> network-> Network adapter Connection-> select Bridged: directly connected to the physical network. After that, nothing to keep.

  That's it for the network card in Virtual Machine of its parameters, and the rest is done to each guest at the guest OS level.

  In Windows 7 host machine, I don't see anything first.

  What we need to do is to assign 3 IP addresses to 3 machines: Win 7, Win XP Guest and Linux host.

  Why the world can't bring you up Google in a browser and type, the ip static windows xp, then static ip rhea of windows 7 and finally static ip.  As I have already said there are more then enough tutorials on the Internet about how to configure a static IP address by a given operating system then I suggest you Google it!  It makes absolutely no sense to write the instructions step by step for you when there are already dozens of tutorials available on the internet.

• Question about snapshots and virtual machines

  Hi all

  I have a small question about snapshots. I use VMware for about 6 months and I read about snapshots and how they work but still have a question to make sure that I understand how it works and it will work the way I think it works.

  I have a Windows 2003 server, which is a virtual machine. I have an application that uses MSDE database. I want to upgrade the database to MS SQL 2005, but to do this I need to back up the MSDE database, uninstall MSDE, and then install SQL 2005 and move the SQL database. This happens on the same VM.

  What I was thinking if I well Snapshots correctly is to snap turned the virtual machine before doing anything. Then do my upgrade steps and see if everything works. If its all messed up so I should be able to return to my shot and everything should be the way he had. What is the good? One of the main reasons I moved the server VM was because of this upgrade.

  After reading the documentation for the snapshots, it's how I undestood it. Pretty much any change could be reversed with snapshots. I wish just they had put in a few examples in the PDF file. Also it would be the same for all type of grades of the OS? Could I snapshot a Windows 2000 Server, and then "in the upgrade of the square" to Windows 2003? I've cloned a VM to do this but was curious about whether snapshots would be just as easy.

  Thanks for your help.

  Exactly the same thing for the upgrades of the OS.

  Perhaps the most important thing with the snapshots is to keep an eye on them and don't let them sit too long or become too big.  You have described the use cases are very good uses for snapshots.  Just make sure you have a solid plan with a schedule set, so that you can come back or validate changes before the snapshot becomes too large.

  Good luck!

• public network for virtual machines, private storage and the service console?

  Hello

  So far I had a pretty small facility with 2 servers with 4 physical network adapters each running ESX 3.5, a small box of EqualLogic SAN to shared storage and a few virtual machines on our network of regular reinforcement, routed, not on a private.   The network config was really simple.  I just put everything on real IP addresses on our network of building.

  Now I want to move the SAN and the traffic on a private service console network, but I don't know how to do this.

  Right now I use 2 NETWORK cards on each server:

  vmnic0 is configured on vSwitch0 and has the network of the VM on it that all my use of VMS to talk to the outside world, and it also has the Service Console that uses Virtual Center and I use ssh to it.

  vmnic1 is configured on vSwitch1 and a VMKernel Port and also a Service Console Port for iSCSI Software to talk to my SAN.  (never been clear on why both are needed to talk to the SAN, but doctors say they are)

  My plan is to set up a vSwitch2 and bind it to vmnic2 and implemented a VMKernel Port and the Service Console Port for software iSCSI on the 10.x.x.x network, set up my new (larger) SAN box on the 10.x.x.x network and simply use Storage vMotion to move virtual machines to the new storage space.  As soon as I did this, I would like to not use the Service Console on vSwitch2 and not a Console Service at all on vSwitch0.  Is it possible to delete the one on vSwitch0 and just use a new vSwitch2 for Virtual Center and ssh access?

  So my proposed configuration would be:

  vSwitch0: VM network only, used by the VM guests for oriented public access network, no construction of Network Service Console, linked to vmnic0

  vSwitch1: superfluous once I do storage vMotion of everything on my old SAN, will eventually remove and pair vmnic 1 with vmnic0, linked to vmnic1

  vSwitch2: VMKernel and Service Console on the network 10.x.x.x, used to access the new SAN, used by Virtual Center to access the ESX, used to SSH in to ESX on private network, associated vmnic2

  If it works?

  Thank you.

  Hello

  VMkernel ports cannot live on the same subnet. So if you have 3 vmkernel ports say: vMotion, iSCSI and NFS. You really need 3 subnets. 1 for each vmkernel port.

  Otherwise how does he know all send properly?

• networking of virtual machine of the internet does not work

  Hi, I am a beginner in Linux, my friend recommend install me VMware 6.0.3 for practice station. I choose the NAT configuration for my virtual machine, because I have a wireless card on my host (winxp-3 Pack), the period of investigation (get automatically from DHCP server) is 192.168.1.1 and 192.168.1.2 is my router to external internet gateway; I set virtual machine sitting in 192.168.88.0 segment. I tried to ping 192.168.1.2 - my physical network adapter, there is no road, looks like icmp knows only 192.168.88.2 (the VMware network adapter is 192.168.88.1), the gateway to the virtual network, but he does not know where to send the packets next hop.

  I put something else to let work?    The snapshot of the configuration is in the attachment.

  Thanks much for any help!

  No, it's quite normal. The gateway by default and DNS for the guest is the IP address of the host VMnet8 + 1 card.

  You can check this by opening the editor of virtual network within VMware Workstation, go to the NAT "tab" and look at the IP address of the gateway. You can also click "Edit", where you can configure (if necessary) DNS servers. But under normal circumstances, the default gateway setting here covers the host DNS queries. They will be transmitted to the DNS server that is configured on the host computer.

  Generally a server should not have multiple default gateways. For the host, it is the default gateway configured on the physical map (otherwise communication would be locked to himself). This is why the army should not have a default gateway on VMnet1 and VMnet8.

  NAT (VMnet8) allows you to communicate with the outside, the guest need default gateway to know where to send the packages which are not intended for the LAN VMnet8 (DNS queries for example). He uses this special IP

• Question on moving a virtual machine from 4.1 to 5.5

  Hello

  My boss put me on the same page brings on virtualization of our systems and we are vMware 4.1 servers migration to a new Server 5.5. It has been their conversion by installing vCenter converter software on the virtual machine 4.1 and selecting 'physical machine' (even if it is a virtual machine) to send it to our Server 5.5. On the other hand, I wanted to install the vCenter on my local PC software and convert 4.1 VMS using VMWare infrastructure to send it to our Server 5.5. Are there benefits or cuts anyway compared to another?

  Specifically, I am curious if the infrastructure mode is slower than "physical machine" because the Server 4.1 must upload to the Server 5.5 through my machine, or if these two servers are just pass between them and my local computer configure work and is able to track progress.

  Thank you

  Hello. Colin

  There are two things you need to consider:

  -the first is the difference between P2V and V2V. Although the 'P' in P2V used to stand for 'physical' it really means 'power' (it is that it displays a UI converter for a few versions now). So, you can virtual machines P2V but they must be turned on. V2V OTOH have to be put off.

  -the second difference is the way in which traffic flows. In the case of P2V source machine pushes the data directly to the destination ESX (source Windows) host or destination VM THAT pull data directly from the source (source of Linux) computer; See pp.11, 12 user guide. In the case of V2V however, data traffic flows from source VM through the converter Server destination of VM. This may cause reduced performance. If your local computer is slow or distant, this decrease can be dramatic.

• Question of moving from virtual machine

  Hey everyone, I have installed virtual machine I need to move from one hard drive to another.  The problem I have is that the destination drive is formatted in FAT32 and cannot send the VM on this disk because it is on the 4 GB file limitation.  I changed the settings to the hard drive to divide it into sections of 2 GB but can't seem to find where these files moved to.  I then looked in the file vmware-vdiskmanager-r sourceDisk.vmdk t 1 targetDisk.vmdk option, but it can not find the hard associated with the virtual machine.  It turns out that when I installed the virtual machine, it all packed in a .vmwarevm file.  I don't know how I can do this now. Any help would be appreciated.  Thank you.

  If you have already selected a 'Divided into 2 GB files' in the settings of the Virtual Machine, you can now copy/move the computer virtual package (.vmwarevm) for the drive/partition/volume formatted FAT32.

  A Virtual Machine package (.vmwarevm) is actually nothing more then a folder containing files (and other files).  Despite its size, as shown in the Finder, as long as 'Divide into 2 GB files' is selected in settings of the Virtual Machine, it can be copied/moved to a FAT32 format volume/partition/drive.

• Question to delete the virtual machine

  Hi all

  ESXi 4.0 and 4.1

  1. when I "delete VM from disk", why sometimes the record (with disk vmdk files) are not deleted? Is this a normal behavior?

  2. If the size of the virtual machine is 100 GB, can I expect that there will be 100 GB of space released in the data store?

  Thank you.

  Fajar.

  (1) why vmdk can be detached? What is the cause?

  1 - in fact the only one - is that the virtual disk has been manually detached.

  (2) why ESXi don't simply delete the entire folder when you are prompted to "remove disc"? You can probably avoid this kind of problem.

  For security reasons, only files that are known to belong to the virtual machine will be removed. The problems you get with deleting too many files is generally much more severe than the one you if a file is not deleted.

  I check the file against the inventory, but it becomes tiring when the folder is located in the shared data store, I check against several hosts.

  In 99% of cases (have you seen, I did not use the word "generally") ' delete drive ' will delete all files related to the virtual machine. In the case of a shared storage you don't have to check on each host, since, in the majority of cases (again once I have use 'usually) all guests have access to the same storage.

  Another reason why the - mainly the vmdk files - files cannot be deleted, is when they are locked. For example, by a hanging backup process.

• 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.

• Simple Question - How to move virtual machines from 1 box to another?

  Hello

  I'm new to VMware products so please bare my stupidity.

  I have 2 servers I received vSphere on. They have all two internal storage (SAN No. still ) which means I can't take advantage of vMotion. So that leaves me to figure out how would one move a Virtual Machine from one box to the other? I currently have two boxes configured with a vCenter Server under 1 datacenter server.

  The simplest solution (considering vCenter) is cold using migrate operation.

• Questions about replication of virtual machines using EMC storage

  Hello

  If we have a configuration on 5200 VNX and ready to replicate to Dominican Republic

  What are EMC replication Solutions, if not use Recoverpoint?
  I have to add licenses of replication with the Suites of the app for that?

  and whether using Recoverpoint, it is essential to use SRM for replication can be configured using Recoverpoint and VNX licenses only?

  and for another program installation is with 10 GB iscsi ports, what are the possible solutions?

  Thank you
  
  

  There are several choices for replication with EMC VNX. You can use Mirrorview. MirrorView/S (synchronous) is for short distances and Mirrorview/A (asynchronous) for longer distances and time of higher latency and low latency. You will need a license from EMC Recoverpoint or Mirrorview. Recoverpoint appliances can now be virtual with version 4. ISCSI is required for a virtual Recoverpoint deployment.

  You don't have to use RS with Recoverpoint, although I would recommend that you do. SRM automates many manual steps that are necessary to retrieve your VMs. SRM will be integrated with Recoverpoint or Mirrowview and you will be able to script recovery plans. In the case of the manual recovery plans would be required and will need to be updated.

  You can also duplicate with suppliers other than EMC software. VMware has built the replication that is fine. Veeam also sells software for replication.
