VCloud in virtual machines cannot communicate if they are in another ESX host

Hi all

Currently I do a simulation for VCD in my laboratory of the company. I just discovered a few question in this simulation. Hope anyone can advice on that. Thank you.

Senario:

1. create an external network with 400 VLANS in vsphere Distribution Switch in two ESX server.

2. create a VCD organization.

3 create a pool of network supported by network isolation VLAN 300

4 create an external organization routed network connection-NAT and select Network (VLAN 400) external and network pool (VCDNI vlan 300)

5. create two virtual machines and assign the same network of the external organization that was created in step 4.

6. If two virtual machines on the same host, they can communication or ping to each other.

7. If two virtual machines in different hosts, they cannot communicate.

Why step 6 and step 7 will happen? What I have set up wrong? Please advice on this.

Much appreciated for your help.

Thank you.

Concerning

Ho

the physical switch must be configured for vlan 400 and 300,

vcni network tries to encapsulate the traffic on the 300 VLAN, if it is not configured on the physical switch virtual machines will be able to talk if they are on the same host.

correct its help is not a network back pvlan Isolation needs its own vlan you set to 300, which she in turn can then run 1000 + mac in the mac encapsulated networks in vlan 300,

Configure the ports on the switch to accept any vlan 300 institutions and it will be sweet

    This error message generally if the hard files have been copied hosted as VMware Workstation product, which uses a format of sparse file that is not supported on an ESXi host. Instead of the hard copy, you can use VMware Converter, or - if you prefer - you can convert the hard using vmware-vdiskmanager (before transfer) or vmkfstools (after downloading). I deal to use vmkfstools you will need to load the mutliextent module (see for example "Clone or migration operations involving virtual discs non-VMFS on ESXi fail with an error" vSphere 5.1 Release Notes)

  • virtual machine cannot start, because the snapshot of the virtual machine has been deleted by mistake.

    virtual machine cannot start, because the snapshot of the virtual machine has been deleted by mistake.

    When I start this virtual machine, it prompts: unable to find the 0001.vmdk, this disc is my shot, has been deleted by mistake.

    How to restore this virtual machine.

    You need help with a revival of the 000001.vmdk deleted or do you want to repair the virtual machine so that it works without the snapshot?

    The last option, follow these steps:
    remove the virtual machine from the inventory and edit the vmx file so that it uses the basedisk. Then add the virtual machine to inventory.
    If you need data from the snapshot call me through Skype "sanbarrow" - I may be able to help

  • New virtual machine cannot reach gateway all-in-olders Yes

    Hi, I'm using ESXi for a year with no problems, but now I'm having a very strange situation. New virtual machine cannot reach the front door, while the 'old'. New virtual machine can ping olders VM and vice versa, but new looks as private. I tried different OS and still have the same question.

    That's what I have:

    Reference DELL R610 with RAID - 1 and RAID-5

    ESXi free 348481 4.1.0

    1 card NETWORK connected

    IPs public 16

    4 VM (W 2008 32bits, W 2008R2 64, 32 2008 W, W 2008 64) works perfectly

    All VM are stored on the local Datastore2 (raid-5)

    Last week, I installed:

    1 Openfiler ESA (gateway problem)

    1 W 2008 R2 (gateway problem)

    1 W XP 32 (gateway problem)

    1 W 2008 32 (gateway problem)

    Older VM never lose connection with gateway and beyond

    New never manage to bridge

    I can't manually add gateway IP/mac address (error 5) in the new.

    Anyone can figure it out and how to solve? I'm really lost.

    Thank you

    New virtual machine can ping olders VM and vice versa...

    This excludes actually questions 'virtual '. The vSwitch has no restrictions.

    What kind of physical switch are you using? If this is a CISCO switch to ensure that the port is configured as a port of access (or trunk port) and spans tree portfast is. Some CISCO switches have a "macro"set desktop on their ports which limits the number of MAC addresses that are allowed on the port.

    PS: Please don't ask me. Did you check the address of the gateway AND subnet mask are correct for the new virtual machines?

  • Can not power on virtual machines "cannot access the file because it is locked.

    Virtual machines have been working well - then the storage system is down.  After the storage system returns upwards that I can't turn on a number of virtual machines.  Get this error when I try to turn it on:

    Cannot power on vmname on esxhostname.xxxxx.com. Unable to access file < unspecified file name > because it is locked
    error

    1. To check the locks on the Service Console on non ESXi servers, run the command:

      lsof | grep

      COMMAND PID USER FD TYPE SIZE NŒUD NOM_PERIPHERIQUE
      71fd60b6-3631 root 4r REG 0.9 10737418240 23533

      Note: If there is no Console of Service process the locking file, you should receive no printed output. If you receive results, however, file a support request to identify the process and to determine the causes.  If it is a third-party process, however, contact the appropriate provider to determine the cause before you kill the process ID, because it can happen again in the future.

      Stop the process and the lock ID using the kill command. In the example above, the process ID is 3631:

      kill the 3631

      After the termination of the process, you can try to turn on the virtual machine or access the file resource.

    2. To check if the virtual machine is always a world ID assigned, run these commands on all ESX/ESXi hosts:

      CD/tmp
      VM-support - x

      Available to debug worlds:
      WID =

      On the ESX/ESXi host where the virtual machine still works, kill the VM, which releases the lock on the file. To kill the virtual machine, run the command:

      VM-support - X

      Where the is the ID of the world of the virtual machine with the locked file.

      Note: this command takes 5-10 minutes to complete. Answer No to "can I include a screenshot of the virtual machine", and answer Yes to all subsequent questions.

      After the termination of the process, you can turn on the virtual machine or access the file resource.

    Deleting the file .lck (NFS only)

    The virtual machine files can be locked via NFS storage. You can identify this as reported by .lck files. # (where # is the ID of the world that holds the lock file) at the end of the file name. It is a NFS file lock and appears only when you use the ls command as it is the hidden file.
    Beware: they can be removed safely only if the virtual machine is not running.

    Note: VMFS volumes have no .lck files. The locking mechanism for VMFS volumes is managed within VMFS metadata on the volume.

    You must kill the process that is locked, if it is not the case, you probably need to restart the VMware host.
    I tell you from experience most likely end up rebooting it.

  • ESXi 3.5 Update 4 virtual machines cannot boot from ISO image stored on the server

    Ok

    If I have one of my virtual machines of ESXi configured to use an ISO image sitting on my server ESXi, they cannot boot from this image.  This is after you click "ESC" during startup in order to change the startup CD-ROM.  I have this a known issue, or I'm just doing something wrong?  If I have the vms use an ISO sitting on my desktop (using Infrastructure Client) it works fine.

    Or the answer is even simpler, make sure I connect at power on.

    OK, Yes!  But some of the things we take for granted... haha...

  • Unable to connect to use Windows XP mode on a Virtual Machine, cannot share files between the Virtual Machine and host

    Because of the need to run some XP programs, I ordered Win7 Pro and installed a Virtual Machine with XP Mode.

    Managed to get it going somehow, but does not connect to my home network (can't see any other computers, which seems to be common with the host of Win 7, but here, I managed to install quick links to other computers - they will not work in XP Mode), even if the Internet connection is working perfectly.

    In addition, I can't find a way to share files with the host country, drive C appears to be different from that of the hosts with no common points (where it is currently stored beats me).

    I can access a USB key, but only at a price to make it unavailable to the host and the attempt to release his capture when running XP Mode failed.

  • Cannot run the application: Java Virtual Machine cannot be loaded. Class not registered

    I want to launch the TI Flash Studio program on my computer windows 7, but the above error when I try to open the program, when I download the suggested 'Virtual Machine' I get another error message that says that the 'Virtual Machine' is not compatible with windows 7, how can I solve this problem?

    Hello hallaman3,

    I did not find TI Studio listed in the Windows 7 Compatibility Center. I suggest that you contact TI to see if they have an updated version.
    I found a new version of TI connect to be compatible with Windows 7. Not sure if you need it for TI Studio.

    You can also try compatibility mode.

    If the program is not compatible, then you try to install and run the program in compatibility mode.

    Use the following steps:

    (1) right click on the program

    2) click Properties

    3) click on the Compatibility tab

    (4) select run this program in compatibility mode and select Windows Vista or other operating system, the program has been run successfully.

    Check out the link here: make sure to run older programs in this version of Windows

    http://Windows.Microsoft.com/en-us/Windows7/make-older-programs-run-in-this-version-of-Windows

    If compatibility is not successful, then try and run the program compatibility problems:

    1. open the troubleshooting program compatibility Troubleshooter by clicking the Start button.

    Then click on Control Panel. In the search box, type troubleshooting, and then click Troubleshooting. Under programs, click on run programs for previous versions of Windows.

    2. follow the instructions in the troubleshooting.

    If you are unable to install a program, insert the installation disc for the program and, using the Troubleshoot utility, navigate to the program setup file, usually called Setup.exe, Install.exe, or something similar. This utility is not designed to work on programs that have an .msi file name extension.

    I hope this helps.

  • Remove a NIC vCloud several virtual machines

    Hello

    I am a vCO and extremely raw newbie with JavaScript (a great combination).  My production environment consist of vCenter 5.0, 5.1 and 5.1 vCO vCD. I have the plugin installed vCD and running with Orchestrator.  I am trying to build a workflow that removes NIC1 (NIC 1) of a series of vCloud VMs.  I took a copy of the vCloud Director Library Workflow (remove a NETWORK adapter) and edited the virtual machines of an input parameter to be an array / vCloud:VM.  I modified the taks script so that it loops through the virtual machines in the array and returns their network adapters.  It seems that the network cards are returned as a UID (I have this return to the screen via a System.Log).  This UID is obviously not with that I entered to the workflow runtime - I said "NIC 1" and my workflow will fail with an error "no primary network connection exists; majorErrorCode = 400; minorErrorCode = BAD_REQUEST; vendorSpecificErrorCode = null; (Workflow: remove a NIC 1 / remove the NIC (item0) #22) " Here is the code I use: .

    If (vm. Status! = VclVMStatus.POWERED_OFF.value) {}
    throw "VM is not off."
    }
    var found = false;
    var len = vms.length;
    for (var i = 0; i < len; i ++)
    {
    var VM = vms [i];
    network var cards = VM.getNetworkCards ();
    System.log (NICS);
    var newNics = new Array();
    for (i = 0; i < nics.length; i ++) {}
    If (. itemResource.elementName.value NIC [i]! = nicName) {}
    newNics.push (nics [i]);
    } else {}
    found = true;
    }
    }
    If (! found) {}
    throw 'Invalid NIC name';
    }
    task = VM.updateNetworkCards (newNics);
    }

    As I mentioned earlier, I am a complete newb to vCO\JavaScript and would be really grateful for some input\advice.  If there is a better method to remove the NIC 1 to a litany of vCloud VMs, or if someone has already developed a workflow for this, I would be very grateful for your help.

    Thank you


    Try this:

    var section = vm.getNetworkConnectionSection();
    System.log("Primary card was NIC : " + section.primaryNetworkConnectionIndex);
    section.primaryNetworkConnectionIndex = 1;
    task = vm.updateSection(section);
    

    He's worked here.

  • Virtual machines cannot access IP host

    I'm running Windows 7 x 64.  I installed VMWare workstation 7.x.  I created a few virtual machines, 3 XP and 1 Windows 7 x 86.   I created a network bridged on the properties of each virtual computer.  Everything worked well for months.   Now, all of a sudden I can not connect to server shares.   In fact, I don't even the IP addresses for all virtual machines.   I tried to sever the virtual machines in the network and the re - add but now I can't even add them because he can't find any field.  I tried uninstalling and reinstalling from VMWare.    I tried all the connections to different network that you can try in VMWare Workstation and nothing works.    I cannot join the domain and I can't get an IP address any.

    I don't know what changed, but something has.  Any help would be great.

    Thank you.

    Have you checked the changes on the firewall of the host or do you use any type of protection software endpoint that is probably blocking the traffic of the virtual machine?

  • Two virtual machines to communicate with each other - intent an SMS Lab for test deployment?

    Hi friends ,.

    I am a new user and would like your help pretty desperately. The scenario is that I want to implement a SMS Lab to deploy the application from the server to a client and test the application. I have all the necessary knowledge to the packaging of application is concerned, and would like to help as much as VMWare is concerned.

    I created two virtual machines and one of them will be configured as a server and the other will be the client. I created a team with these two machines in it. I am trying to ping from one machine to the other and its does not work. I only use the method of configuration host. The idea is simply to make the two systems communicate so that I can finish the entire configuration and use the same SMS deployment lab.

    -First of all, I'm new to all this so I would like to know whther to everything I do is correct and what is the largest possible?

    -What I have to do something else to make sure that those two communicate about someother or any other configuration software is necessary?

    I would like to ask you guys to be a little more specific are you when you help others that I need you guys ore than a person who is used to working on VMWare.

    And just so you know if it helps, I use VMWare Workstation 6.0.

    What you are doing is reasonable.  Both of your virtual machines have an IP address on the same subnet?  In general, the scenarios no-ping, the first thing to check is the firewall in the guest computers.  Have you checked that allows ping traffic?  If it is disabled?

  • New virtual machine cannot see host DVD rom

When I go in the settings of the virtual machine and try to set up DVD to use the host device, I get the message that no device is available. Help...

    SATA has always been a little flakey when it comes to ESX.  You should maybe update your BIOS or make some small changes in the BIOS for him to see the player.  A quick fix would be to create an ISO of the DVD that you want to use and upload it to your data store to use until you get the problem solved.
