1. In the environment where FusionSphere OpenStack is connected to KVM, when a virtual machine is created, ( ) will calculate a node suitable for establishing a virtual machine through a series of algorithms, and notify ( ) to complete the creation of the virtual machine.

Nova-Conductor，Libvirt

Nova-scheduler，Nova-Compute

Nova-Compute，Nova-Conductor

Libvirt，Nova-Compute

2. In the FusionSphere private cloud solution, which of the following descriptions are incorrect about the principle of rapid virtual machine release? (Multiple Choice)

When you issue a virtual machine, you do not need to create a new system volume in the storage and copy the full amount of the mirrored content to it.

When issuing a virtual machine, the system only needs to quickly create a lightweight sub-volume, and the existing parent volume constitutes the complete system volume of the virtual machine.

During the use of the virtual machine, all modifications to the system volume are written to the subvolume

The system volume ID that the virtual machine presents externally is the ID of the parent volume used by it.

3. The control node of FusionSphere OpenStack can provide NTP services.

TRUE

FALSE

4. When using the Rainbow migration, the source can be a physical server, VMware or Hyper-V virtualization platform, and the destination is the FusionSphere platform.

TRUE

FALSE
