+# When the VxHS network block device server is set up appropriately,

+# (qemu processes) and the remote VxHS server.

+# It is necessary to setup CA and issue the client certificate before

+# This is used to authenticate the VxHS block device clients to the VxHS
+# server.
+#
+# If the provided path does not exist then the default_tls_x509_cert_dir
+# path will be used.
+#
+# VxHS block device clients expect the client certificate and key to be
+# present in the certificate directory along with the CA master certificate.
+# If using the default environment, default_tls_x509_verify must be configured.
+# Since this is only a client the server-key.pem certificate is not needed.
+# Thus a VxHS directory must contain the following:
+#
+#  ca-cert.pem - the CA master certificate
+#  client-cert.pem - the client certificate signed with the ca-cert.pem
+#  client-key.pem - the client private key
