Hi ALL, did any attempt on the virtual computer NETWORK load balancing using HYPERV on UCS blades

I try to configure the CASE server cluster by using the Unicast NLB on the virtual machine on different blades on the UCS, it works for awhile, then he abandoned packages.

I heard that this screenplay of unicast is not supported in the UCS when she used END-host mode in the fabric interconnet...? any attempted before.

Would it, I use the multicast mode is that something needs to be done on the FBI62020 or the LAN switch upstream. ??

Header note I found on the implementation of UCS for mulitcast NLBL:

Microsoft NLB can be deployed in 3 modes:

Unicast

Multicast

IGMP multicast

For series B UCS deployments, we have seen that the multicast and IGMP multicast work.

IGMP multicast mode seems to be the more reliable deployment mode.

To do this, the monitoring settings:

All NLB Microsoft value "Multicast IGMP" nodes.  Important!  Check ths by logging into EACH node independently.  Do not rely on the MMC of NLB snap.

An IGMP applicant must be present on the VLAN of NLB.  If PIM is enabled on the VIRTUAL LAN that is your interrogator.  UCS cannot function as applicant IGMP.  If an interrogator of functioning is not present, NLB IGMP mode will not work.

You must have a static ARP entry on cheating it upstream pointing IP address Unicast NLB on the multicast MAC address NETWORK load balancing.  This need will set up, of course, on the VLAN of the NLB VIP. The key is that the routing for the NLB VLAN interface must use this ARP entry as a unicast IP ARP response may not contain a multicast mac address. (Violation of the RFC 1812)  Hosts on the NLB VLAN must also use the static entry.  You may have several entries ARP.  IOS can use a function of 'alias' of ARP. (Google it.)

How Microsoft NLB works. -The truncated for brevity Mac addresses.

TOPOLOGY OF NLB MS

NETWORK VLAN 10 = subnet 10.1.1.0/24 IP load balancing

VIP = 10.1.1.10 NETWORK LOAD BALANCING

Arp entry static switch advanced IP 10.1.1.10 upstream to MAC 01

NLB VIP (MAC 01, IP 10.1.1.10)

NODE-A (AA, MAC IP:10.1.1.88)

NŒUD-B (MAC BB, IP:10.1.1.99)

Using the IGMP snooping and interrogator VLAN snooping table is filled with the mac NLB address and groups pointing to the appropriate L2 ports.

MS NLB nodes will send the responses of IGMP queries.

This snooping table could take 30 to 60 seconds to complete.

Host on VLAN 200 (10.200.1.35) sends traffic to NETWORK VIP (10.1.1.10) load balancing

It goes of course to VLAN 10 interface that uses the static ARP entry to resolve to address MAC 01 VIP NETWORK load balancing.

Since it is a multicast frame destination it will be forward by the IGMP snooping table.

The framework will arrive at ALL NLB nodes. (NŒUD-A & NŒUD-B)

NLB nodes will use its load balancing algorithm to determine which node will manage the TCP session.

Only one NLB node will respond to this host with TCP ACK to start the session.

NOTES

This works in a VMware with N1k, standard vSwtich and vDS environment. Where surveillance IGMP is not enabled, the framing for VIP MAC NETWORK load balancing will be flooded.

NLB can only work with TCP-based services.

As stated previously mapping an IP unicast to a multicast mac address is a violation implied by RFC 1812.

TROUBLESHOOTING

Make sure your interrogator is working. Just to clarify that this does not mean that it is actually at work.

Wireshark lets check that IGMP queries are received by the NLB nodes.

Make sure that the ARP response works as expected.  Once Wireshark again is your friend.

Look at the paintings IGMP snooping. Validate the L2 ports appearing as expected.

Q: and if I switch to switch mode, which means all of the profile and the settings on the servers are completely exhausted and I need to recreate them. ???

  • Strange problem after moving from the virtual computer to a new data store

    I am migrating our VM existing (8 in total) a 'problem' RAID to a new table on a new controller and am having a strange problem. Here are the steps I took (host OS is Ubuntu 8.0.4 LTS x 64):

    (1) off the power the virtual computer from the Web interface

    (2) the directories created for each virtual on the new RAID array computer (in this case a RAID 10 array on LSI 9750-8i controller)

    (3) rSync used to copy the data from RAID1 to be RAID2

    4) has created a new data store on the new RAID through the Web Server of VMWare user interface.

    (5) removed VM of the inventory through the Web, their return, added user interface then choose files .vmx on new data store on RAID2

    They have all power save fine... but three of them are not accessible on the network. I can open a console in the Web Server of VMWare user interface and they all run normally... but I can't their ping or access the respective virtual machine Web GUI. It seems quite arbitrary that those who work and those who are not. In this case... the VM that don't work is a license Autodesk, a Squid proxy server and a VM of cactus. All three of these virtual machines are 32-bit Ubuntu Server VM (two 8.0.4 and a 10.0.4)... and are the only Ubuntu VM on this host. It must be signifigant but I'm not see how.

    If I delete these three virtual machines of the inventory again and add to their original location (on the RAID1) they light up AND work normally. A consultant that we were working seemed surprised, as he had also done this experiment with some of the older VMWare products. I don't see how it would be the physical location of the files of the virtual machine. Any ideas?

    We rely on the migration to ESXi soon but in the meantime, we get these a few VM out of this RAID array problem. I'm stuck.

    Depending on the application, it may be enough to reconfigure the IP parameters (they are very probably on DHCP now) for the newly detected virtual NIC.

  • After the Virtual Machine is hot migrated lose the reference to the virtual computer object (VMware.Vim.VirtualMachine)

    Hello

    In my VB.Net application, I retrieve the virtual computer object (VMware.Vim.VirtualMachine) through scripting Powershell VI.

    If the Virtual Machine is migrated to another host (hotmigrate) I receive an event (VMware.Vim.VmMigratedEvent), which also holds the moref of the Virtual Machine. I tried to use the updateview method to refresh the virtual computer object but failed with an error message stating that the object could not be found, or never existed.

    I also tried to recover the virtual computer object again, throug the method Client.GetView and the moref returned by the event, but the same error message.

    How can I get my hands on the virtual computer object or update after migration to another host takes place. I have to get it back again? It would be great if I could do it somhow with information from moref I hold the event!

    Any help is appreciated!

    Concerning

    Manfred

    Sorry, but I can only show you how to do this in PowerShell.

    I use the purpose of the task to get to the prompt MoRef.

    Here's how:

    $vmName = 
    $tgtHost = 
    $tgtPool = 
    
    $vm = Get-VM $vmName | Get-View
    $poolMoRef = (Get-ResourcePool $tgtPool | Get-View).MoRef
    $esxMoRef = (Get-VMHost $tgtHost | Get-View).MoRef
    
    $task= Get-View ($vm.MigrateVM_Task($poolMoRef, $esxMoRef, "lowPriority", "poweredOn"))
    
    while($task.Info.State -eq "running" -or $task.Info.State -eq "queuing"){
      $task.UpdateViewData()
    }
    
    $vmImpl = Get-VIObjectByVIView -MORef $task.Info.Entity
    

    I don't know how you get at the VmMigratedEvent event, but the MoRef in there is pointing to the correct prompt.

    In the following script, I extracted all the events related to the task of vMigrate immediately after the vMigrate task finished

    function Print-VmName{
         param($event)
    
         $MoRef = New-Object VMware.Vim.ManagedObjectReference
         $MoRef.Type = $event.vm.vm.type
         $MoRef.Value = $event.vm.vm.Value
         $vm = Get-View $MoRef
         Write-Host $vm.Name
    }
    
    $events = Get-VIEvent -Start (Get-Date).addminutes(-15)
    $events | % {
         $event = $_
         $eventType = $_.GetType().Name
         switch ($eventType){
              "VmMigratedEvent" {
                   $eventType
                   Print-VmName $event
              }
              "VmEmigratingEvent"{
                   $eventType
                   Print-VmName $event
              }

  • Is it possible I can get the virtual computer connectivity after restart to connect to the local network in the host operating system?

    Hi all

    For some reason, I have to disable and then enable the LAN connection in the host operating system. If some virtual machines are running during this time, connectivity all VMs for out-of-world are lost, they cannot connect to the host even more (by running the ping command). I tried a few methods to retrieve the connectivity, but all have failed, for example,

    1. reboot the virtual computer

    2. restart VMware Workstation

    3. restart the corresponding system services in the host operating system

    The only way I can retrieve all is to restart the host operating system itself.

    Yes, is there short any path, I can retrieve the connectivity of these virtual machines?

    Thanks in advance.

    You add the SCSI ID of the tape (and the library, if any) to the virtual machine.

    Or, if your hardware can he take charge, using VMDirectPath and give the card on the virtual computer.

    Using the VirtualMachineRelocateSpecDiskLocator to move disks from different NFS data warehouses when cloning a model looks very good work.  However, the Virtual Machine configuration file and the location of work remain on their original NFS data storage, not moving with the root of the drive.

    If this move not all together, or am I missing a step here?

    Thank you

    Scott

    Specifying the "data store" in VirtualMachineRelocateSpecDiskLocator specifies the location of the VM virtual disks only. To move the virtual machine, it might also be necessary to specify "datastore" property of "VirtualMachineRelocateSpec. If this is not specified, the current data store is used to store the files of the virtual computer.
