Drift
of 0.001126 PPM as compared to physical machine 0.002984 PPM.
Service migration (HA/BCP)
Monitoring
showed spike in CPU due to Open SIP & increased time(~1000%) to stabilize connections.
Resource contention to simulate
Multi-Guesting triggered failover. Separate hardware recommended for standby server.
