Description (partial)

When the VM is moved using vMotion, there's a traffic interruption to it that lasts from several seconds to several minutes (up to Local Endpoint Retention interval, which is 15 minutes by default, depending on where the traffic is coming from and the BD Unknown Unicast setting).

Happens when BD is associated with FHS (First Hop Security) policy that has the IP Inspection enabled ("default" FHS policy, for example).
