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.

Some months ago I installed 15 new vSphere 6.0 hosts with local flash disks. After installation I configured the VMware Syslog Service at the vCenter appliance. Few weeks later the vSphere web-client shows some warnings about disk usage

Problem

Filesystem /dev/mapperlog_vg_log usage 100%, mounted on /storage/logs

 
Use this command to verify which disk is experiencing disk space issues:

 

 

 

 

 

 

 

 

 

 

 

 

Solution

As you can see the the /storage/logs mount point is located at VMDK5

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Edit de vCenter appliance virtual hardware, select disk Hard disk 5 and increase the provisioned size, in my case from 10 to 20 GB

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Once the virtual disk has been increased, return to the SSH session and execute this command to automatically expand any logical volumes for which the physical volumes are increased:

vpxd_servicecfg storage lvm autogrow

 

 

 

 

 

When the grow operation is successful, you see output similar to:

VC_CFG_RESULT=0

 

Run this command to confirm that the virtual disk has been successfully grown:

df -h

Last week I deployed with Update Manager some patches at an existing vSphere 6.0 environment, during the remediate process I received this error message:

 

 

 

The operation is not supported on the selected inventory objects. Check the events
for the objects selected for the operation.

 

Solution

During the Remediate process you need to disable Admission Control, also when you have enough resources available in the cluster. You can do this for this specific host you selected for remediate or you can you this temporary at cluster level

Last week I upgraded my original Configure vSphere 4 PowerCLI script I created in 2011 . When you run the script with PowerShell ICE or PowerCLI you have two options: 1. Configure a new vSphere 6 host. 2. Add the new configured host to vCenter Server. I’m still not a PowerCLI Pro so.. please comment if you have any tips or suggestions.

Benefits:

— When you use this script, the script is your vSphere configuration documentation
— You don’t need a license for Host Profiles or revert temporary to Evaluation Mode
— Fresh (new) host configuration takes ~10 minutes
— vSphere Host configuration standardization
— Easy add variables during deployment
— Easy GUI menu

 

Function:

Menu option: 1 – Configure new vSphere host

— Connect to the target ESXi Host
— Enter Maintenance mode
— Set Hostname and Domain name
— Configure DNS settings
— Configure NTP settings
— Configuring Simple Network Management Protocol (SNMP)
— Delete the default VM Network
— Configure vSwitch0 – Management / vMotion
— Configure vSwitch1 – Production Network
— Configure vSwitch2 – iSCSI
— Configure vSwitch3 – iSCSI
— Install Software iSCSI Initiator
— Configure iSCSI target address
— Configure iSCSI initiator name
— Enable iSCSI Initiator
— Rescan on all HBAs and Rescan for VMFS volumes
— Exit Maintenance Mode

Menu option: 2 – Configure new vSphere host to vCenter Server

— Connect vCenter server
— Add vSphere Host to vCenter server
— Re-balance Cluster

Menu option: 0 – Quit

 

Script upgraded for hardware setup:

Host

— Type: Dell PowerEdge R630
— Network: 6x 10 GB
— Storage: flash (2×8 GB)
— Memory: 256 GB
— CPU:  2x E5-2660 v3

Storage

— Dell Compellent SC4020 (iSCSI)

Network

— DellForce 10

During upgrade VMware vCenter Server 5.5.0 (based on Windows 2012R2) to 6.0.0 I received a warning message:

Error: There is a problem authenticating into the legacy vCenter Server using the credentials provided by the user.

Resolution: Check if vCenter Server is up and running. Double check provided vCenter Server credentials

 

 
Some troubleshooting:

• All VMware vCenter Server Services are started
• No warnings/errors in Microsoft Event Logs during setup
• I can logon at the vSphere webinterface with credentials [email protected]
• When configure wrong SSO password in setup the setup says "The vCenter Single Sign-On credentials are not valid. Check the username and password and try again"
• I can ping domain controller VMpros.local
• I canceled the setup and generated a support file, at the time I received the warning message this setup log was generated, so far, nothing special:

Solution

Reboot the vCenter Server… I restarted the setup and the installation can continue.. weird!

Everyone knows the hanging keyboard console session issue, when you type your username or password the keyboard hangs. If you access a virtual machine console over a slow connection, you’ll encounter keyboard sync issues

If you open a remote console to a virtual machine from a slow network connection (such as a VPN) while tethered to a mobile phone providing Internet access, the experience is not optimal, as keyboard and mouse gestures aren’t timed exactly the same. This is especially problematic if you try to enter a password where the characters are masked.

  

Solution

There are two ways to add a extra line in the configuration file of the virtual machine,

 

Option 1. Edit VMX file directly

1. Power off the virtual machine.

2. Add a line, similar to this, at the end of your virtual machine’s configuration (.vmx) file

keyboard.typematicMinDelay = "2000000"

The delay is specified in micro-seconds, so the line in the example above increases the repeat time to 2 seconds. This should ensure that you never get auto-repeat unless you intend it.

3. Power on the virtual machine.

 

Option 2. Edit VMX via vSphere Client

1. Power off the virtual machine.

2. Edit settings > Options > General > Configuration Parameters, add new row with text:

keyboard.typematicMinDelay = "2000000"

The delay is specified in micro-seconds, so the line in the example above increases the repeat time to 2 seconds. This should ensure that you never get auto-repeat unless you intend it.

3. Power on the virtual machine.

 

Ps. You can edit the .VMX files directly, but a better practice is to configure this value within the vSphere Client for a virtual machine template. When you consider that most of the access to a virtual machine is provided by tools such as remote desktop, there is no harm in configuring this value globally for all virtual machines that originate from a template

Last week I had some issues with starting virtual machines on vSphere 5.5 hosts (enough capacity available), when I try to start up the VM I receive message:

Could not start VMX: msg.vmk.status.VMK_NO_MEMORY”

An error was received from the ESX host while powering on VM [name]
Head globalCartel-1 already at its maximum size of 7869288. Cannot expand
Could not start VMX: msg.vmk.status.VMK_NO_MEMORY

 

Cause

This issue is caused by a memory leak in the driver which fills the SWAP memory of the ESXi host, making it unable to response to any requests at all. This issue occurs with ESXi hosts running on HP hardware with these versions of AMS:

• hp-ams 500.9.6.0-12.434156
• hp-ams-550.9.6.0-12.1198610
• hp-ams 500.10.0.0-18.434156
• hp-ams-550.10.0.0-18.1198610

Solution

This is a known issue affecting ESXi 5.x. To resolve this issue, upgrade to AMS version 10.0.1.

For ESXi 5.0 and 5.1, see:

• HP Agentless Management Service Offline Bundle for VMware ESXi 5.0 and vSphere 5.1.

For ESXi 5.5, see:

• HP Agentless Management Service Offline Bundle for VMware vSphere 5.5
• HP ESXi Offline Bundle for VMware vSphere 5.5

 

Note: In some cases, commands running on the ESXi host fails with cant’t fork.  In this case the virtual machines running on the ESXi host needs to be powered off and the ESXi host rebooted. To verify the installed versions of AMS, run this command:

esxcli software vib list | grep ams

To remove the package on all hosts running on these AMS versions:

1. Log in to the host using SSH. For more information, see Using ESXi Shell in ESXi 5.x and 6.0 (2004746).
2. Run this command to stop the HP service (does not persist on reboot):
   /etc/init.d/hp-ams.sh stop
3. Run this command to remove the VIB:
   esxcli software vib remove -n hp-ams
4. Reboot the host.
