/*
 * Internal flags to keep track of qemu command line capabilities
 *
 * As a general rule these flags must not be deleted / renamed, as
 * they are serialized in string format into the runtime XML file
 * for guests, and new libvirt needs to cope with reading flags
 * defined by old libvirt.
 *
 * The exception to this rule is when we drop support for running
 * with older QEMU versions entirely. When a flag is no longer needed
 * we temporarily give it an X_ prefix to indicate it should no
 * longer be used in code. Periodically we can then purge all the
 * X_ flags and re-group what's left.
