Hello,

I know how to add a vm machine using vmotion, but I wanted to know what occurs in the background when moving a vm machine via both vmotion and HA?

vMotion does take part in VMware HA, no data on the shared storage moves in a VMware HA operation. The VM stored on the shared storage device, always remains in once place and does not move, the same is true of a vMotion.

It's the VM running process which moves!

When a host fails, the Fault Domain Manager agent on the hosts, restarts the VM on other hosts in the Cluster. For this it de-registers the VM from the failed host, and restarts on other hosts, the data does not move, it remains on shared storage.

vMotion, the live migration of virtual machines, again the data does not move, it's stored on the shared datastore, what occurs, at the moment you issue a vMotion, is the memory space is recorded of the VM this is sent across the vMotion network to the other Host, at a time, when the VM is not busy, the remaining memory contents and pointers are transferred to the other host, and the vMotion completes.
