For this, use sdl=1 in the guest config file.

For this, use vnc=1 in the guest config file.

Additionally use vnclisten='0.0.0.0'
to connect via vnc from *any* host in the network.

Use vncpasswd='mypasswd' to password protect the vnc.

Further, vnc connection can be encrypted via TLS
when you enable the options vnc-tls in /usr/pkg/etc/xen/xend-config.sxp
Note, after editing this config file, you always must restart xend.

The option vnc-x509-cert-dir tells where qemu-dm finds the certificate.
qemu-dm requires a client certificate if vnc-x509-verify is enabled.
