Sure.
For example, windows guest user want to enable windows remote desktop to touch
guest(UDP/TCP 3389),
This case use UDP and TCP mixed, and the tcp part payload always different
caused by real desktop display data(for guest time/ mouse display....).
Another case is some real user application will actively transmit information
include guest time part, primary guest send data with time 10:01.000,
At the same time secondary guest send data with time 10:01.001, it will always
trigger COLO checkpoint to drop guest performance.
