We all know the little blue bar in VMware that tells us the progress of an action. But what does the percentages mean and what is the problem when the action fails at a certain percentage?

To make this all a little more clear, I made a list of the stages and there respectively definition.

vMotion Percentages:

9% NIC, update firmware   (Link)
10% General system   error, Network Connection/DNS/Time Sync (Link)
10% Operation timed out,   LogRotationSize to small (Link)
