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. 🙂

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

We’ve purchased Dell PowerEdge R710 which arrived build in with quad network adapter , and we’ve added to it additional quad port network adapter.

We’ve installed on the server ESX 4. The problem was that after connecting to the server from vSphere client , it recognized only 4 network adapters (the build in quad port network adapter) and not the additional quad port network adapter.

How can we install drivers for the second quad port network adapter?

Solution

  • Check on your server’s quote what is the type and model of the quad port network adapter.
  • We’ve found out that our quad port network adapter was Intel’s  model 82576.
  • I’ve opened http://www.google.com and typed the following: VMware ESX 4 Driver CD for Intel ,and the first link was a perfect match: http://downloads.vmware.com/d/details/esx40_intel_82580_v4002198_dt/ZHcqYmRwakBiZCVodw==
  • I’ve downloaded the ISO to my computer.
  • Download and install the software: Tunnelier (SSH Client) from the following path:  http://www.bitvise.com/download-area
  • Using Tunnelier (SSH Client) connect to your ESX host on which you would like to install the quad port network adapter. (Make sure you connect as Administrator)
  • After connecting through Tunnelier (SSH Client) to your ESX host , two windows will open: 1. Bitvise SFTP (the windows window) 2. Bitvise xterm (the SSH window)
  • Using Bitvise SFTP ,(from the left side of the window) navigate on your computer to the path which you saved the ISO (Intel’s Driver CD for VMware ESX 4).
  • From the right side of the window – navigate to:  /usr/lib/vmware/isoimages (you will notice that after double clicking “isoimages” you will be transferred automatically to /vmimages/tools-isoimages – it is OK, you are on the right track :)), drag the ISO file from the left side of the window to the right side of the window, and wait until the transfer will finish.
  • From the SSH window (Bitvise xterm) write the following: mount -o loop -t iso9660 /usr/lib/vmware/isoimages/ISONAME.iso /mnt/cdrom , for example: mount -o loop -t iso9660 /usr/lib/vmware/isoimages/vmware-esx-drivers-net-igb_400.1.3.19.12.1-1.0.4.164009.185976.iso /mnt/cdrom

            

  • From the SSH window (Bitvise xterm) write the following: mount

            

  • From the SSH window (Bitvise xterm) write the following: cd /mnt/cdrom/offline-bundle
  • From the SSH window (Bitvise xterm) write the following: esxupdate –bundle=INT-intel-lad-ddk-igb-1.3.19.12.1-offline_bundle-185976.zip update

                             

  • Wait until receiving successful message.

             

  • Restart the ESX server.
  • After the restart, connect to Tunnelier (SSH Client), from the SSH window (Bitvise xterm) write the following: esxcfg-nics –l , you will be able to see the additional 4 ports which you have just installed the drivers to.

            

  • And from the vSphere client you will be able to see it as well by going to : Stand on the host > Configuration > Networl Adapters

             

 

Fixed!

Problem

We created a datastore that contain ISO files, and we wanted to grant permissions to users in order to attach these ISO files into their virtual machine’s CD-Rom. (in addition to the regular operations as power on/off and managing snapshots).

Solution

In order to do that I created a special Role , below you can find the content of that role.

  • Connect to the vSphere client
  • Go to Home > Role > Add new Role > Snapshots & Connect ISO
  • Check the following permissions:
    • Datastore > Browse datastore
    • Virtual Machine > Configuration > Modify device settings
    • Virtual Machine > Interaction > Configure CD media
    • Virtual Machine > Interaction > Console interaction
    • Virtual Machine > Interaction > Device Connection
    • Virtual Machine > Interaction > Power on
    • Virtual Machine > Interaction > Power off
    • Virtual Machine > State > Create snapshot
    • Virtual Machine > State > Remove snapshot
    • Virtual Machine > State > Rename snapshot
    • Virtual Machine > State > Revert to snapshot
  • Go to Home > VMs and Templates and > Stand on a certain folder > Permissions,  and add this role (Snapshots & Connect ISO) to a user on that path, for example :

            

  • Go to Home > Datastores > Stand on a certain datastore which contains the ISO files (in my example Emcvm-Images2) > Permissions > and add this role to the same user as you added on the folder (Snapshots & Connect ISO) ,for example :

              

  • The user will see as follow (Right click on the virtual Machine > Edit Settings) :

             

Fixed!
