The placement attribute can be either "static" or "auto". It must be between 1 and the maximum number supported by the hypervisor. Vcpu defines the maximum number of virtual CPUs allocated.
The unit attribute behaves the same as for memory. If this is omitted, it defaults to the same value as the memory element. This value can be less than the maximum allocation, to allow for ballooning up the guests memory on the fly. In case NUMA is configured for the guest, the memory element can be omitted.ĬurrentMemory represents the actual allocation of memory for the guest. However, the value will be rounded up to the nearest KiB by libvirt, and may be further rounded up to the granularity supported by the hypervisor. Memory represents the maximum amount of memory allocated to the guest at boot time. If omitted, a new UUID will be generated. Can be committed when defining a new machine. Uuid is a globally unique identifier for the virtual machine. The guest ("domain") name may contain dot, so we can simulate a hierarchy ("ose36.master", or "environment-name.host-in-environment-name"). Also conventionally, it is also the name of the file storing the virtual machine image, with the ".img" prefix. Ideally, it should follow the virtual machine name convention when naming virtual machine. Must consists of alphanumeric characters and it must be unique per virtualization host.
