The nova.compute.vm_mode
Module¶
Possible vm modes for instances.
Compute instance vm modes represent the host/guest ABI used for the virtual machine / container. Individual hypervisors may support multiple different vm modes per host. Available vm modes for a hypervisor driver may also vary according to the architecture it is running on.
The ‘vm_mode’ parameter can be set against an instance to choose what sort of VM to boot.
