VMware -VM Management
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
