charset="utf-8" OptsVisitor, StringInputVisitor and the keyval visitor have three different ideas of how a human could write the value of a boolean option. Pay homage to the backwards-compatibility gods and make the new common helper accept all four sets (on/off, true/false, y/n and yes/no), and case-insensitive at that. Since OptsVisitor is supposed to match qemu-options, adjust it as well. Supersedes: <20201103142344.402353-1-pbonzini@redhat.com> Signed-off-by: Paolo Bonzini Reviewed-by: Daniel P.
