VMware: Disable HotPlug capability for virtual machines with PowerCLI

January 16th, 2016 2 comments

Last week I had to change VMX files for 500 XenDesktop machines because the users where able to eject removable devices

To mass disable HotPlug capability by editing the .vmx file via PowerCLI I used the following script:

$key = "devices.hotplug"
$value = "false"
get-cluster "CL02.XD" | get-VM -Name 000-CXD* | foreach {
  $vm = Get-View $_.Id
  $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec
  $vmConfigSpec.extraconfig += New-Object VMware.Vim.optionvalue
  $vmConfigSpec.extraconfig[0].Key=$key
  $vmConfigSpec.extraconfig[0].Value=$value
  $vm.ReconfigVM($vmConfigSpec)
}


Optional (manual) options:

You can disable HotPlug capability using the vSphere Client or by editing the .vmx file.
Note: You can disable HotPlug capability for PCI devices such as e1000 or vmxnet3 NICs.
To disable HotPlug capability using the vSphere Client:

  1. Connect to the ESXi/ESX host or vCenter Server using the vSphere Client.
  2. Power off the virtual machine.
  3. Right-click the virtual machine and click Edit Settings.
  4. Click the Options tab.
  5. Click General > Configuration Parameters > Add Row.
  6. Insert a new row with the name devices.hotplug and a value of false.
  7. Power on the virtual machine.

To disable HotPlug capability using the vSphere Web Client:

  1. From a web browser, connect to the vSphere Web Client.
  2. Log in with Administrator credentials.
  3. Navigate to the virtual machine you want to modify.
  4. Right-click the virtual machine and select Edit Settings.
  5. Click the VM Options tab.
  6. Click Advanced > Edit Configuration > Add Row.
  7. Insert a new row with the name devices.hotplug and a value of false.
  8. Power on the virtual machine.

To disable HotPlug capability by editing the .vmx file:

  1. Power off the virtual machine.
  2. Access the ESXi/ESX service console using an SSH client.
  3. Open the virtual machine configuration file (.vmx) in a text editor. The default location is:
    /vmfs/volumes/datastore_name/vm_name/vm_name.vmx
  4. Add the line:
    devices.hotplug = "false"
    Note: This setting does not interfere with HotPlug CPU/memory.
  5. Save and close the file.
  6. Power on the virtual machine.

VMware: Toggling the vCenter Server Appliance 6.x default shell

December 18th, 2015 No comments

This article provides vSphere Administrators steps to toggle between default shells available on the vCentrer Server Appliance (vCSA). 

Currently, the vCSA is bundled with these supported shells:

  • Appliance Shell
  • BASH Shell
    Today I tried to upgrade vCenter Appliance 6.0.0 to Update 1, after runnning command “software-packages stage –iso –acceptEulas” I receiver message:

    -bash: software-packages: command not found

image

 

Switching the vCenter Server Appliance 6.x to Appliance Shell

 

  1. Log in to the vCenter Server Appliance via SSH.
  2. Run this command to change from using the BASH Shell to the Appliance Shell:

    chsh -s /bin/appliancesh root

  3. Log out from the BASH Shell and re-log in for this to take affect.

Result

After restart the SSH sessoin I was able to run commands in bash shell

VMware: Perf Charts service experienced an internal error

December 16th, 2015 No comments

A few weeks ago a customer asked me to take a look at the following warning message in VMware vCenter when the Performance Tab in the vSphere client is being opened.

  

Perf Charts service experienced an internal error.

Message: Report application initialization is not completed successfully. Retry in 60 seconds

 
image


Troubleshooting time

Global checks:

  • The Windows Event logs are clean
  • VMware vSphere (web-) services are started with normal credentials
  • I was able to restart service accounts with domain based credentials (no locking)
  • Windows Firewall was enabled but no drops in the logging
  • No recent installed Windows Updates
  • No unplanned restarts or crashes
  • The installed certificate was not expired
  • The installed certificate was 2048 bit
  • No conflicting webserver ports at the vCenter server
    ..some more troubleshooting

I checked the wrapper.log and stas.log files located at the following location:

Path: C:\ProgramData\VMware\VMware VirtualCenter\Logs\

clip_image002

 

 

 

 

 

 

 

 

 

  

clip_image002[5]

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Hmm, he logging shows that there are problems with the installed vCenter SSL certificate:
 

Error constructing private key..

..Error decrypting password

After some troubleshooting I saw that every time I open the Performance tab a new webserver SSL private key decrypting error was written in the stats.log.

I already had checked the expire date of the installed SSL certificate, it was a normal 2048 bit wildcard certificate.. oh, eh, wildcard..?? Let’s see if it is supported:

“The use of wildcard certificates are not supported with vCenter Server and its related services. Each service must have its own unique certificate”

Nope, it is not! Maybe this is the root cause.

After checking the SSL requirements at the VMware KB  I found the SSL format which is needed to generate the certificate: OpenSSL Version 0.9.8 must be used. If you do not use this version, the SSL implementation fails. <– I couldn’t check this because there was no documentation of the SSL generation

 

Solution

The customer used a wildcard SSL certificate which is not supported
