Valid memory element identifier and multiplier values
The 'unit' attribute for the <memory> element in the libvirt domain XML file for provisioning guests automatically accepts specific identifiers and multiplier values.
If you do not allocate accepted values, such as those shown in the following table, the system displays an error message about an unrecognized allocation unit.
For example, the
<memory unit='G'>4</memory> XML snippet attempts to allocate 4,294,967,296 bytes of memory (4,294,967,296 = 4 * 1,024 * 1,024 * 1,024) for the guest. The default memory allocation unit is 1,024 bytes.
| Identifier | Value |
|---|---|
| b | 1 byte |
| bytes | 1 byte |
| KB | 1000 bytes |
| k | 1024 bytes |
| KiB | 1024 bytes |
| MB | 1000 * 1000 bytes |
| M | 1024 * 1024 bytes |
| MiB | 1024 * 1024 bytes |
| GB | 1000 * 1000 * 1000 bytes |
| G | 1024 * 1024 * 1024 bytes |
| GiB | 1024 * 1024 * 1024 bytes |
| TB | 1000 * 1000 * 1000 * 1000 bytes |
| T | 1024 * 1024 * 1024 * 1024 bytes |
| TiB | 1024 * 1024 * 1024 * 1024 bytes |
