As explain in my previous email, Ivshmem in qemu only accepts size in MB or GB.

To prevent this error, we should not accept size under 1MB, in
virDomainIvshmemDefParseXML:

 if (virDomainParseScaledValue("./size[1]", ctxt,
 -                             &def->size, 1,
 +                            &def->size, 1024x1024,
                               ULLONG_MAX, true) < 0)
