• Belvedere on the installer of Windows 7 virtual machine on the server

  We currently have a SCADA running Lookout 6.0.2 and you want to upgrade to 6.7.1.

  I interested him running Lookout 6.7.1 on Windows 7 virtual machine on a server.

  Someone has done this? Have tested the lookout 6.7.1 on a PC with Windows 7, I have no idea if the lookout will run on the virtual machine.

  Is - this in anyway beneficial define Lookout this way? Need information please.

  All the ma, but two of my servers run under VMs on Hyper-V.  The other two are running on (remote) VMware enterprise configurations.  Everything works beautifully.   I use Ethernet Server series brands such as Moxa or Pearl for any devices that are not native ethernet.  I even ran Ethernet USB on a few occasions, but that can be risky.

• How to migrate a virtual machine from the server with DAS to another server

  Hi guys,.

  questions. 'More' essential Kit. VMotion is available

  I have 2 physical servers, two of them have DAS (not SAN Central). SO I want to migrate a virtual machine on server A to server B. is it possible in this situation?

  Or should I have versions of more expensive VMWare do?

  Thank you
  Dmitry

  You can use clone. I would close first to the bottom of the virtual machine, but a VM slowed would be very nice clone. You can also use the VMware conveter. VMware converter can make a hot clone, including synchronization of last-minute changes, stop the source machine and put under tension the clone.

• HA restarts the virtual machine if the storage connectivity is lost? If how is HA needs to be configured?

  We plan to go forward with a single dual-port HBA in each of our ESX servers. My concern is that the HBA becomes a single point of failure. HA supports restarting the virtual machine which lose connectivity to back-end storage. We did some testing and it does not appear that HA does not handle this. Even when 'enable us VM monitoring' the machine virtual do not restart on other ESX servers in the cluster that they hang just basically. I've read a few articles which seem to indicate that it should work, but I'm not able to get there. Any thoughts there?

  HA checks the availability of default ESX host. There is an option to monitor the heartbeats reviews, as well. Maybe this will do, but sometimes a guest still works for awhile even if the disk is lost. And as for a long time VMware tools send heartbeats...

• PowerCLI Script to migrate virtual machines with the same network Source for the new vCenter Server.

  Hi all

  I checked a few posts on the migration to the new vCenter Server virtual machine. But I'm not very good with Powercli and need some help here.

  We have a new vCenter server where we migrate virtual machines from one source vCenter server. Here are two things that I don't know how to connect together to make sure that bwfore we turn on the virtual machine to the virtual machine is connected to its source network.

  Part 1 - this script works well but do not get any network on the vCenter destination.

  cluster = Get-Cluster "clusterA.

  $inventory = get-Cluster $cluster | Get - VM | Add-Member - MemberType ScriptProperty-name "VMXPath" - value {$this.extensiondata.config.files.vmpathname}-Passthru-Force | Select-Object Name ResourcePool, folder, VMXPath |

  $inventory | Export-Csv c:\file.csv

  $inventory = import-csv c:\file.csv

  $cluster = get-group 'b '.

  {foreach ($vm to $inventory)

  $ESXHost = get-Cluster $cluster | Get-VMHost | Select - 1 first

  New-VM - VMFilePath $vm. VMXPath - VMHost $ESXHost - location $vm. Folder - ResourcePool (Get-Cluster $cluster |) Get-ResourcePool $vm. ResourcePool)

  }

  Part 2 - I want to preserve the Portgroup macaddress and the Ip of the virtual computers and connect them to the new vCenter. How can I do this with the script below. Or how can I combine them together?

  $vm_list = get-Cluster-name "clustera | Get - VM test * | Name sort

  $information = {foreach ($vm to $vm_list)

  $network_adapter_information = get-NetworkAdapter - VM $vm

  $vm | Select Name,PowerState,ResourcePool,@{N="Path; E=       {$_. ExtensionData.Summary.Config.VmPathName}},@{N="NetworkAdapter '; E = {[string]: join (":", ($network_adapter_information |))} %{$_. {{(Nom + "," + _.NetworkName $}))}}, @{N = "MacAddress"; E = {[string]: join (",", ($network_adapter_information | % {$_.}))} MacAddress}))}}

  }

  Step 2

  # Unsubscribe virtual machines

  Remove-VM - VM $vm_list-RunAsync Verbose - confirm: $false

  Step 3

  $cluster = get-group 'b '.

  {foreach ($vm to $inventory)

  $ESXHost = get-Cluster $cluster | Get-VMHost | Select - 1 first

  New-VM - VMFilePath $vm. VMXPath - VMHost $ESXHost - location $vm. Folder - ResourcePool (Get-Cluster $cluster |) Get-ResourcePool $vm. ResourcePool)

  }

  # Save virtual machines

  foreach ($info in $information)

  {

  $vmxpath = $info. Path

  $resource_pool = $info. ResourcePool.Name

  New-VM - ResourcePool (ResourcePool-Get-name $resource_pool) VMFilePath - $vmxpath - RunAsync-Verbose | Out-Null

  }

  Step 4

  # Put the network cards

  foreach ($info in $inventory)

  {

  foreach ($network_information in ($info.NetworkAdapter - split ":"))))

  {

  $virtual_machine = $info | %{$_. Name}

  $network_adapter = ($network_information-split ",") [0]

  $network_vlan = ($network_information-split ",") [1]

  Get-VM-name $virtual_machine | Get-NetworkAdapter-name $network_adapter | Together-NetworkAdapter - NetworkName $network_vlan-Verbose-RunAsync-confirm: $false | Out-Null

  }

  }

  # Start the virtual machines

  foreach ($vm to $vm_list)

  {

  Start-VM - VM $vm. Name-RunAsync Verbose - confirm: $false | Out-Null}

  }

  Thanks in advance for any help.

  Hi all

  I made some changes to the script and it worked for me. We have added a host on the destination with all exchanges and storage mapped vCenter.

• Practically in segregation a virtual machine within the same network

  We have a VMware ESXi 5.0.0 (504890) host that has physically 4 network cards. We run 3 VMs on that host and turning a new config. However, this new virtual machine will replace our old Windows DC, DNS, server DHCP etc., and we'd like to config it before going live - will not perform us a migration of swing. We are a little worried that it can interfere with our direct network and that's why I would like to somehow almost segegrate it.

  For the moment, we have a single vSwitch0 linked to all our VMs and management card:

  

  What is the best way to do this so that our new DC (with the same domain name and within the same network) can be configured without it interfering with the current network.

  Thanks for your comments.

  Oliver

  Hello

  You can create a second vSwitch without physical network interface cards. Create a VM Portgroup on this vSwitch.

  You can configure your new virtual machine to use the Portgroup. So, he won't have any connection to your network.

  The good thing is, when you want to test things with a customer, you can create a second VM and configure it to the same VM portgroup on the second vSwitch.

  Two virtual machines on this Portgroup can communicate with them because the traffic is handled internally by the host.

• Network problem in the virtual machines on the same switch

  Hello

  I'm stuck on a problem with my small network.  I have an ESXi 5 host that hosts around 10 virtual machines.  The last two machines I install recently displayed an unexpected behavior.  I can't do a ping between the two machines or in those 2 VMS to anywhere else in the same subnet or other networks.  These two VMS, I am able to ping and have network connectivity.  Two of these virtual machines reside on the same vSwitch and belong to the same group of port as other machines.

  The configuration of these two VMs appears to be identical to all other virtual machines that work properly.  The two guest virtual machines running Windows Server 2008 R2.

  So far, I tried several static IP and DHCP assignments with the same effect.  (Including spend another virtual machine a static IP at work known to one of the computers virtual problem)  I tried to delete and re-create one of the virtual machines completely.  I also did an upgrade from 5.0 to 5.1 for vCenter, ESXi host and virtual machines, and I am always observing the same behavior.

  Any advice on what to check next would be greatly appreciated.  Thanks in advance.

• Can't export virtual machines: unable to connect to the remote server

  Hello

  I'm working on vSphere client 5.1 (vCenter Server 5.1). Trying to export a virtual machine for distribution model. When I go to file-> export the template OVF..., I get the following error message:

  Can't export virtual machines: unable to connect to the remote server

  Remote not sure what/who he is not able to connect to. If I connect vSphere Web Client and navigate to the same model (or all other models), under 'All the Actions of vCenter' I don't have an option to export to the model of the FVO. But if I use a VM machine instead of a virtual machine template, I have the ability to export to the OVF, but it is grayed out.

  Am I missing any customer authorization or plugin for vShpere?

  Discovered that vSphere server had some modifications made by HIM to resolve the violation POODLE. HE had to set the ip address of the machine where export OVF will be performed. Which allowed the connection to establish vsphere client and perform an export of the FVO.

• network stream between 2 virtual machines in the same vlan and host using DVS

  Hi experts, so 2 virtual machines on the same vlan / subnet and on the same esxi host using VDS need to talk to each other, that they get switched by the VDS internally or they headed north for network switches and come back?

  Welcome to the community - it will stay internal to the ESXi host.

• is it possible to access the virtual machine when the network is down...

  Hello. He... IAM wondering is it possible that we can access the virtual machine when the network is down... (Because of power outages or when the fluctuations...) ................?

  Is it possible that I can configure my Virtual Machine...?

  Thank you and best regards...

  Hello

  Not really...

  For an environment hosted... If you can access the console of the host, you can always access the console of the virtual machine regardless of the State of the network outside of the console. VMware Workstation, Fusion and server all fall into this category.

  For ESXi/ESX... you need a host outside to access the console of the virtual machine. ESX and ESXi not displayed graphics or VMs of their consoles and management devices. So, you need an external machine that can run the vSphere Client or access to the virtual machine via RDP, VNC according to Guest OS involved or SSH.

• Hang a new virtual machine to the Internet

  All virtual machines that I downloaded connect to internet automatically when I their fire upwards. I downloaded a new machine virtual de VulnHub, specifically BrainPan2. It does not connect to the internet automatically even if it is supposed to. It's a vulnerable VM installation for security penetration testing. Now, I start my VM Kali, do a scan of the network and see all my computers. I'll start a VM unrelated, rerun the scan and check the other appears. Now I launch BrainPan, run the scan and nothing. I don't see on the scan.

  I read several guides associated with the virtual BrainPan2 of the internet machine, and everyone seems to be able to plug in and go. On the site of the BrainPan: 'import brainpan2.ova into your privileged hypervisor and configure the settings of the network to your needs. It will get an IP via DHCP, but it is recommended that run you to the breast of a NAT or visible by the host only operating system because it is vulnerable to attack."

  So, I put the virtual machine to run on NAT, connected by a bridge and also host. I can't detect the virtual machine by any means, it just is not auto-connect. And I can not connect and plug it as he did to hack.

  Does anyone have any suggestions?

  Hi John,.

  I'm using the regular VMware Fusion, not Fusion Pro. Fusion Pro is a virtual network editor that could help; I do not know. Just for fun, I downloaded BrainPan2 VM, and it worked only. Here are the steps I took:

  • Go to Brainpan: 2 ~ VulnHub
  • Click Download, which exposes the download link.
  • Download the file brainpan2.zip and unzip it.
  • Check the integrity of the downloaded file brainpan2.ova. In terminal, type 'openssl sha1', and then drag the file brainpan2.ova to the Terminal to fill in the full path of the brainpan2.ova file. Press return. Compare the sha1 hash in the terminal with one on the web page of the BrainPan. If they do not match, try again download.
  • Open VMware Fusion 8 and choose file-> import. Drag the file brainpan2.ova to the window. Click on the button continue and save the converted virtual machine. VMware Fusion will display a progress bar as it converts the file .ova. It took a few minutes on my Mac. Once the conversion is completed, you will see a window Finished.
  • Click Customize settings.
  • As part of the network card, select private to my Mac.
  • Start the virtual machine of BrainPan2. I don't bother to upgrade the hardware. You will see a login prompt, which I ignored. The BrainPan2 virtual machine will get an IP address from the DHCP server on VMware virtual network.

  Optional:

  • Open the BrainPan2.vmwarevm file in the Finder. Right-click to display the contents of the package. Open the vmware.log with a text editor like BBEdit or TextWrangler or even TextEdit. Search for "192.168" and you will find two entries to the VMware virtual networks. On my system, the private sector in my Mac network was vmnet1 to 192.168.166. * (I guess that the other network is the "share with my Mac" NAT.) He was appointed vmnet8.)
  • Close the log file.

  Instead of Kali Linux, I used one of my virtual machines in OS X, because it was very convenient. (My Kali Linux virtual machine are saved on an external drive). The virtual machine of OS X I used runs El Capitan, but any version of Mac OS X.

  • Take a snapshot of the OS X machine for two reasons: (1) to maintain its normal parameters and (2) because I don't trust the BrainPan2 virtual machine to not attack the OS X machine on the VLAN.
  • After the snapshot set network configuration of the virtual machine of the OS X private to my Mac, so that it is on the same virtual network as the virtual machine of BrainPan2.
  • Start Mac virtual machine. In the terminal, type "ifconfig en0" to see its IP address on the local network deprived of VMware. There are other ways to find the IP address, of course. My virtual machine to OS X has been awarded 192.168.166.129, so I figured though the virtual machine of BrainPan2 has been assigned to 192.168.166.128, which proved to be just.
  • If it is not already installed, download nmap or Zenmap or tools of everything that you need. A Kali Linux preinstalled.
  • Run a scan of the LAN ping. Example: ' nmap - sn 192.168.166. * "you should see the virtual switch to 192.168.x.1, your virtual Kali Linux or OS X machine and the virtual machine of BrainPan2 (mine was 192.168.166.128 as I suspected). The virtual machine BrainPan2 responds to the pings.
  • At this point, I ran a scan of port of the virtual machine of BrainPan2. Not wishing to spoil your fun, I will only say that I found the open ports on the BrainPan2 virtual machine.

  Don't forget to restore your virtual machine OS X (or Kali Linux) to the previous snapshot once you are done with BrainPan2, if nothing else, but to restore access to the Internet by moving out of virtual private LAN.

  I hope this helps. Please let us know if you are able to make it work. I hate to write solutions and then never discover what happens then.

• PowerCLI script to migrate virtual machines to the new vCenter environment

  Hello world

  in the next few weeks, we need about migrate 700 VMs (Windows/Linux) server to a new environment (new vCenter, new hosts, but VMs will remain on same data warehouses). VMs will be migrated not in one batch, but rather from time to time (which, however, can understand the need to migrate some 10s of virtual machines at the same time).

  Cluster names and folder structure will be identical to the old and the new vCenters. As host in the new vCenter names differ from those in the old vCenter, thought to provide a table of 'translation', which tells the script to save a given VM on host B (new vCenter) when having been registered in order to host a (old vCenter) and so on.

  I thought writing a PowerCLI script which, broadly speaking, can accomplish the following steps:

  • Connect to vCenterOld and vCenterNew
  • Correspondence table of host to read from a file (see step "register VM vCenterNew below)

  Then, in a loop:

  • Ask VM name
  • Get the settings of the virtual machine: Datastore/path, network/Portgroup, HA restart priority, host, folder, note
  • View the parameters and the VM name and request confirmation migrate the virtual machine
  • Turn off VM (closed OS gracefully, but force power off if power status is still not equal 'off' after a time given)
  • To unsubscribe from VM vCenterOld (removal of inventory)
  • Registry of the VM to the data store vCenterNew (assumptions: same folder as vCenterOld, host names are different, but for each source in vCenterOld host a host of destination in vCenterNew for you join the virtual machine to can be provided, that is, CSV)
  • The value of VM portgroup (same name as in vCenterOld)
  • Set VM HA restart priority
  • PowerON VM
  • Wait / check the VM (for example, ping) connectivity / continue immediately if the virtual machine is accessible or after a certain time if the virtual machine is still inaccessible
  • Confirm that the virtual machine has been migrated successfully, OR ask the user to check the connectivity of the virtual machine

  Now to my questions:

  • Is anyone know about an existing script that does something similar or contains parts that can be useful to compile a script like this?
  • How can vCenter two connections at the same time been managed within a PowerCLI script - or doesn't work at all and a connect/disconnect to/from the two vCenters must be completed for each virtual computer?

  Many thanks for any help.

  The following seems to work for me

  $vm = Get-VM -Name MyVM$nic = Get-NetworkAdapter -VM $vm $vdPG = $nic | select -ExpandProperty NetworkName

• Models of virtual machine in the library of content focus type = unknown

  Hello

  I created a test with vsphere environment 6 and I created a content library for my VM models.

  That worked well for the last few months, but today I have connected the web client and wanted to deploy a new virtual machine from the content library.

  First thing I noticed was the selection after "deploy vm from library" - the library is empty...

  When I look directly in the content library, models are still there, but the type is unknown and not possible to export the s model or deploy...

  Any ideas what I can do?

  I already rebooted the server vcenter...

  I found a work around...

  I was able to clone the model with type = unknown, and the watch type = clone model vm and the guest OS is displayed correctly, too...

• Tagged management VLAN and the virtual machines on the same VLAN

  I'm faced with a problem related to our Brocade switches newly acquired and get the private VLAN to work on trunk connections to our ESX servers.  Every time I try something different, he creates a new problem.

  In our configuration, our management of VLAN is not tag and we have a VLAN for this management network that is placed on our switches VLAN no marked native.  We also have virtual machines hosted on those same ESX servers that are on the same VLAN and everything works fine.  However, when I change the ESX management to carry a label on this VLAN and change the switchports accordingly (IE no untagged VLAN native), management work, but hosted on the ESX Server machines that are on the same VLAN can get no network connectivity.

  Is it possible to have a management network labeled and also the host of virtual machines on the same VLAN or is it totally impossible?  I'm not very familiar with networking behind ESX, so I apologize if this is a dumb question with an obvious answer.

  Thank you

  Mark J.

  Is it possible to have a management network labeled and also the host of virtual machines on the same VLAN or is it totally impossible?

  Yes, it is possible... why it doesn't work for you I don't know, but try the following:

  1. set up the Group of ports of VMS to use VLAN;

  2 configure the interface of management VMkernel port group use VLAN;

  3 configure the physical switch port to allow to this VLAN and put the default VLAN natively for these interfaces.

• Virtual machine in the DMZ

  Hello

  We have 8 guests ESXi 5.0 in our internal network, network cards connected to 2 internal switches of the kernel.

  Can I do below;

  (1) create a new virtual switch "vSwitchDMZ" on one of the host, with "DMZ_VLANid".

  (2) assign a NIC to this vSwitchDMZ

  (3) connect this adapter to the physical switch DMZ port (this port will be access VLAN for this id VLAN individual)

  (4) create a new virtual machine with 1 NIC and assign it DMZ_VLANid

  Question:

  (A) I need to create 2 virtual machines in the DMZ. I can do it, or there is risk involved?

  (B) If no, then how the maintenance of the 2 mV in DMZ can be achieved? We have no license Cisco Nexus 1000v.

  Hope that I am able to explain my concern.

  Thank you

  Mihir

  A.) Yes it is possible. As long as the virtual machines connect only to the DMZ vSwitch, and DMZ vSwitch has only an uplink to the physical DMZ pass it's ok form a networking perspective.

  You can even create a DMZ switch on each of the hosts to use HA and vMotion for VM in case it is needed.
