This is not the way you connect to a HVM console, unless you configured
the HVM guest to use a serial console. By default it's the HVM's virtual
The virtual framebuffer can be displayed in 2 ways, depending on the config
1) using the SDL library. qemu-dm will open a X window on the $DISPLAY
from which xm create was run. If $DISPLAY isn't valid, I think the
guest will start without console display.
For this, use sdl=1 in the guest config file.
2) qemu-dm act as a vnc server. You connect to the console using vncviewer
on localhost. As you only have one guest, I guess it''ll be
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.
