What is VM HA? How to achieve this function ?

Concept: When a physical server or a virtual machine fails, the system automatically starts the virtual machine in the resource pool to another available physical server. The physical machine fault type: the host is powered off, restarted, and down.

Virtual machine OS failure type: Windows blue screen, Linux Panic and other features:

1. VM failure or compute node failure

2. The management node queries the VM status and finds that the VM is faulty.

3. The management node determines that the VM has the HA attribute, and selects the available one based on the saved VM information (specification, volume).

CNA boot VM

4. The CNA node receives the HA request and starts a new VM based on the VM specification and volume information.

5. Remount the volume before the VM, including the user volume, during the boot process

Failure - "Detection -" Load VM configuration file - "Pull up VM-" pull up business
