The 'size' of a 'shmem' device is parsed and formatted as a "scaled" value, stored in bytes, but the formatting scale is mebibytes. This precission loss combined with the fact that the value was validated only when starting and the size is formatted only when non-zero meant that on first parse a value < 1 MiB would be accepted, but would be formatted to the XML as 0 MiB as it was non-zero but truncated and a subsequent parse would parse of such XML would parse it as 0 bytes, which in turn would be interpreted as 'default' size. Fix the issue by moving the validator, which ensures that the number is a power of two and more than 1 MiB to the validator code so that it'll be rejected at XML parsing time.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
