Vmotion is licensed Virtual infrastructure feature
that performs the migration of RUNNING virtual machines with NO downtime.
·
Vmotion requires a centralized SAN or NAS to store the
VM as the VM never really leaves the central storage
·
To use VMotion you must configure a new VMKernel network
interface on each system(you need to create dedicated Vmnetwork for it).
·
That Vmotion network transmits memory of the systems
·
Darning that time, all the changes are stored in a
bitmap on the host and is the last thing to be Moved to the new server
·
The gust has a very short quiescent state when moved
to new host while memory bitmap is moved
·
Prior to being moved ,the machine is evaluated and
there are lots of opportunities for errors as the two host machines and
configuration must be very compatible
