Are you sitting? If not – please do 🙂

In vSphere 5 VMware has removed any patch operation support in virtual machines.

According to “http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-update-manager-50-install-administration-guide.pdf” – Update Manager 5.0 does not support virtual machine patch operation.

Update Manager 5 , can performs the following:

  • VMware Tools and virtual machine hardware upgrade operations, Update Manager works with ESX/ESXi version 4.0 and later.
  • ESX/ESXi host patching operations, Update Manager works with ESX/ESXi 3.5 and later.
  • ESX/ESXi host upgrade and migration operations, Update Manager works with ESX/ESXi 4.0 and later.

My mantra is always be prepared. Get ready for VMware vCloud implementation today!

In addition, if you’ll think about it – it’s the most reasonable thing to do. If you’ll have a problem with your main cluster , would you like the entire management servers including the vCenter (!) to be affected ?

I recommend to separate your management servers into different cluster , including creating a different storage group for this purpose.

Try it, you won’t regret it. 🙂

Problem

Today I encountered a problem in installing  VMware vSphere client on my windows 7 desktop (x64), when I tried to install the client I got the following error:

Many times I need to use VMware icons and images in presentations and professional documentation.

The following links have fantastic VMware icons and images.

I hope it will contribute you like it did to me 🙂

Problem

We wanted to enable VMware EVC on our cluster (cluster 1) but we couldn’t enable the EVC , because in order to be able to enable EVC – all virtual machines must be powered off , and our vCenter server as a virtual machine, was standing in our way.

Solution

  • Take one ESX server from cluster 1 and insert it into maintenance mode.
  • Remove ESX server from cluster 1 .
  • Create a new cluster (cluster 2)
  • Add the ESX server which you have just removed from cluster 1 to cluster 2 (make sure not to change anything in the storage configuration in that ESX server – the ESX server has access to the old cluster LUNs)
  • Use Live migration (vMotion) in order to migrate vCenter server from cluster 1 to cluster 2

             

  • Power off all virtual machines in cluster 1.
  • Enable EVC on cluster 1 ( stand on the cluster > Edit Settings > VMware EVC > Change > Enable EVC for Intel Hosts)

             

              

  • Connect using the vSphere client directly to the ESX host in cluster 2.
    • Stand on vCenter Server virtual machine.
    • Right click > Edit Settings > Options > General Options > Virtual Machine Configuration File.
    • Write down the full path of the vCenter server virtual machine.
  • Connect using SSH to the ESX host in cluster 2.
    • Navigate to the vCenter path (which you’ve found out in the paragraph above)
    • Copy the full path (including *.vmx file).
    • From the SSH, power off vCenter server. Using the following command : vmware-cmd “Virtual_Mchine_Full_Path.vmx”  stop
    • In order to check if the vcenter server has powered off, run the following command: vmware-cmd “Virtual_Mchine_Full_Path.vmx” getstate
    • After you’ll see that the server is powered off , unregister the virtual machine from the ESX host in cluster 2 , using the following command:
      • vmware-cmd –s unregister “Virtual_Mchine_Full_Path.vmx”

                                         

  • Afterwards connect using SSH to another ESX server in cluster 1.
    • Register vCenter server in that ESX server using the following command:
      • vmware-cmd –s register “Virtual_Mchine_Full_Path.vmx”

                               

    • Make sure that the vCenter server has successfully registered in the new ESX server, and is currently powered off using the following command:
      • vmware-cmd “Virtual_Mchine_Full_Path.vmx” getstate
    • Power on vCenter server virtual machine using the following command:
      • vmware-cmd “Virtual_Mchine_Full_Path.vmx” start
    • Answer vCenter server virtual machine’s question.
      • vmware-cmd “Virtual_Mchine_Full_Path.vmx” answer
    • Create a new identifier by choosing 0
  • Enter the ESX which exist in cluster 2 into maintenance mode.
  • Remove the ESX from the cluster.
  • Add the ESX server to cluster 1.
  • Delete cluster 2.

Fixed! You have just configured EVC in cluster 1, and returned vCenter server virtual machine back to that cluster 1.

Problem

I connected an external DVD, but I couldn’t use it because I received the following error message: “is not accessible , Incorrect function”  (see photo below)

Solution

Go to device manager and disabled the default CD-ROM device.

Problem solved 🙂
