@item tls-ciphers=<list>
Specify which ciphers to use.
@item tls-channel=[main|display|inputs|record|playback|tunnel]
@item plaintext-channel=[main|display|inputs|record|playback|tunnel]
Force specific channel to be used with or without TLS encryption. The
options can be specified multiple times to configure multiple
channels. The special name "default" can be used to set the default
mode. For channels which are not explicitly forced into one mode the
spice client is allowed to pick tls/plaintext as he pleases.
@item image-compression=[auto_glz|auto_lz|quic|glz|lz|off]
Configure image compression (lossless).
Default is auto_glz.
