[libvirt] [PATCH v5 6/9] conf: Add new secret element for tcp chardev
John Ferlan
jferlan at redhat.com
Thu Aug 4 15:21:24 UTC 2016
Define, parse, and format a key secret element for a chardev tcp backend.
This secret will be used in conjunction with the chartcp_tls_x509_cert_dir
in order to provide the secret to the TLS encrypted TCP chardev.
<secret type='tls' usage='tlsexample'/>
