You cannot use the standard VNC console to connect to virtual machines on a SPARC-based server pool. Instead, use the serial console. The serial console can also be used to connect to virtual machines running on x86-based server pools although the console, in this case, is read-only and non-interactive.

Any firewall between the Oracle VM Manager and the Oracle VM Servers needs ports 10000 and above open; one port for each virtual machine on an Oracle VM Server. For example, if you have 100 virtual machines on an Oracle VM Server, you should open ports 10000-10099 (100 ports) on any firewall between the Oracle VM Server and Oracle VM Manager.

To connect to a virtual machine's serial console in Oracle VM Manager, you must install the appropriate package on the Oracle VM Manager host computer.

Ensure that you are using a supported web browser when accessing the serial console.

See Launch Serial Console for more information on using the serial console to connect to virtual machines in SPARC-based server pools.
