The following incorrect description of memory reuse is

A. memory reuse technology can make the sum of virtual machine memory specifications larger than the sum of physical server specifications

B. memory reuse technology can make the total memory used by virtual machines larger than the total memory of physical server specifications

C. After the C memory reuse function is enabled, the memory reuse rate is inversely proportional to the actual memory usage of each virtual machine.

D. memory reuse single technology includes memory bubbles, memory swap and memory sharing

The following description about making templates in FusionCompute is incorrect .

A. "Virtual machine to template" is to directly convert a virtual machine into a template, all parameters use the current configuration of the virtual machine The virtual machine will no longer exist after conversion

B. When using a virtual machine to make a template, the status of the virtual machine can be "running"

C. "Clone a template as a template" is to copy the template as a new template and support adjustment of some parameter configurations, which can be slightly different from the original template The difference is that the template still exists after cloning is complete

D. "Clone a virtual machine as a template" is to copy the virtual machine as a template and support adjustment of some parameter configurations, which can be compared with the original virtual machine. The virtual machine is slightly different. The virtual machine still exists after cloning is complete.
