Cannot Display Graphical Installer When Creating Guests
The following example as a VNC configuration entry in a hardware virtualized guest configuration fie:
vnc = 1 | # vnc=1 enabled, 0=disabled |
vncconsole = 1 | # vncconsole=1 enables spawning VNC viewer for domain's |
| # console. Default=0 |
vnclisten = 0.0.0.0 | # Address that should be listened on for the VNC server |
#if VNC is set. Default (if vnc=0) is to use
#
vncunused = 1 | # | vncunused=1 - | find an unused port for the VNC server |
| # | to listen on. | Default=1 |
In this example, the vncunused=1 parameter allocates a new VNC port number each time a guest is created and assigns it to the guest. Port numbers are allocated starting at the default VNC port number of 5900, so dom1 is allocated port 5900, dom2 is allocated port 5901, dom3 port 5902, and so on.
Connect to the guest on the host computer with the command
vncviewer
The
ipaddress:port
In both examples, ipaddress is the IP address or hostname of the Oracle VM Server, and port is the VNC port number of the guest.
E.4 Cannot Display Graphical Installer When Creating Guests
If the graphical installer does not start when creating a guest using the
ssh root@example
export DISPLAY=example:0.0
Alternatively, you can enable connect to a console and enable ssh forwarding using the ssh
ssh
If you use Putty to connect to a console, you must connect from an X11 capable operating system.
E.5 Hardware Virtualized Guest Console Not Displayed
If a console is not displayed after you create a hardware virtualized guest, your disk device specification may be incorrect. When you create a hardware virtualized guest, you must specify the VNC console setup. This is not required for a paravirtualized guest.
