Lets Design, Implement and do Administration of ESX3

Virtualization with VMWare Infrastructure 3.0

VMware -VM Management

Posted by Preetam on February 19, 2007

You can move VM’s between ESX servers. Moving VM’s when they are power off it is called Cold Migration. So what would be Hot Migration, nothing but VMotion. We will deal with it in more details in later posts. Cold migration of VM gives you option to move the files to different datastores, but in most cases Datastores are shared and ESX shouldn’t have problem in accessing those files. In case situation where it is not possible to access these files, files are also moved along.

So when you perform Cold Migration ?

  • When you would like to move VM’ to local datastore of ESX server
  • And when VM’s are to be moved to two different CPU families
  • Or when are upgrading your ESX hosts

Adding Devices:

VM need to be Power Off for adding most of the devices, Except for Hard disk, which is called Hot Plug. In case you need to add additional NIC, you can do only when the VM is power off. In order add device, Power off VM. In the summary tab, click Edit settings, VM properties are displayed. Click on add hardware Wizard and select the device you would like to add.
