VMware: Repeated characters when typing in remote console

April 7th, 2015 No comments

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.




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

VMware: Upgrade vCenter Server 5.5 to 6.0

Last week I upgraded VMware vCenter 5.5 server (based Windows 2012R2) at the company environment I work for, the upgrade was very simple.

Pre-install: Please check article “Minimum requirements for the VMware vCenter Server 6.x Appliance (2106572)

[VMware] Could not start VMX: msg.vmk.status.VMK_NO_MEMORY

March 29th, 2015 2 comments

Last week I had some issues with starting virtual machines on vSphere 5.5 hosts, 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




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


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:

For ESXi 5.5, see:


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.

VMware: What’s new in vSphere 6.0

February 3rd, 2015 No comments

Install & Upgrade

  • Enhanced Install and Upgrade Capabilities – Windows vCenter installation experience has been enhanced with additional capabilities including custom ports, custom paths, uninstall and error messaging improvements. Furthermore, all upgrade paths from Windows vCenter 5.0 and up are now supported. vCenter Server Appliance now has a guided installer. Separate ISOs and scripted installation for both vCenter Server for Windows and vCSA reduce the overall download time and improve automation capabilities respectively.


  • Expanded Support for New Hardware, Architectures, and Guest Operating Systems – Expanded support for the latest x86 chip sets, devices and drivers. Added support for FreeBSD 10.0 and Asianux 4 SP3 guest operating systems.
  • Increased Scalability – Increased configuration maximums in vSphere 6: Cluster maximums have increased to support up to 64 nodes and 6,000 VMs. Virtual Machines will support up to 128 vCPUs and 4TB vRAM and Hosts will support up to 480 physical CPUs, 12 TB RAM, 64 TB datastores, 1000 VMs and 32 Serial Ports. Increased support for virtual graphics including Nvidia GPU.
  • Instant Clone – Technology built in vSphere 6 that lays that foundation to rapidly clone and deploy virtual machines, as much as 10x faster than what is currently possible today.
