Whether automatic migration is supported
When the CPU usage of a computing blade is high, the system can automatically migrate some of its VMs to other blades whose CPU usage is low. When the CPU usage of multiple compute nodes is low, the system can also migrate their VMs to just a few blades and power off the idle ones. The system can automatically migrate VMs at a user-specified time and set a speed limit of 1000 Mbit/s or 100 Mbit/s for vNICs. The system cannot automatically migrate VMs based on network traffic or storage I/O throughput.
