Vmware high availability is a great feature of vmware. If you have shared storage like SAN / NAS  you can create high availability by using two ESXI servers , so when any physical server goes down or its network connectivity looses, VM High Availability auto takes over and migrates the virtual guest machines off that server to another server.

[Please note that In case of any ESXi host failure, the vm files never copied/moved, only the ownership of those virtual machines is transferred from the failed host to the new host. This way, the virtual machines can be up and running again in just few seconds or the time required to boot that specific guest VM(s)]

Requirements:

  • You must have VMware Infrastructure Suite (FREE or FOUNDATION version not supported).
  • At least 2 ESX host systems for high availability.
  • A shared NAS or SAN between the ESXi Servers where the virtual machines will be stored. In case of any ESXi host failure, the vm files never copied/moved, only the ownership of those virtual machines is transferred from the failed host to the new host.
  • Try using same hardware for both ESXI servers to avoid compatibilities issues.

sorry, 😦 Due-to time shortage, I will write it more about it later. for info , email.

Howto power on Vmware Workstation guest machine

Some one asked me howto power on Vmware Workstation guest machine via CLI.  you can use vmrun tool to power on the machine by using target vm guest .vmx file. I decided to write the simple method for my reference too, because I also use it heavily in my virtual lab.

To achieve it, You can create a shortcut on your desktop so that you can quickly start your required workstation base virtual machine by clicking a single icon on your desktop. OR if you want to power it automatically after windows starts, you can create a simple shortcut or batch file and add it windows STARTUP.

SCENARIO:

You have install vmware workstation in H:\vmware_workstation and your guest vm is in H:\temp_images_ubuntu-proxy , then simply use the following shortcut.


D:\vmware_workstation\vmrun start  D:\vmware_images\ubuntu-proxy\ubuntu.vmx

Tip: vmrun is available in workstation folder.

Also read following for more references.
