Opening a Virtual Machine Console Session

To resolve an issue where the VM console window does not open

Allow the required Java™ plugins to load in your web browser. For information about enabling Java, see Web Browser Requirements.

If you still have problems opening the VM console session, you may need to ask your network administrator to open ports 6900-6999 (inclusive).

To resolve an issue where the VM console window is blank

Verify that the VM is powered on and not in the process of booting. Also, click in the console window and press any key to deactivate the screen saver.

To resolve an issue where more than one VM console window is displayed and they are behaving erratically

Close all console windows and open only one console window.

To resolve an issue where the VM console window hangs on the everRun system

For Ubuntu-based VMs, the VM console hangs if you do not properly set the gfxmode parameter. In the guest operating system, edit the /boot/grub/grub.cfg file and change the gfxmode parameter to text (for example, set gfxmode=text).

If the console hangs before you can set the parameter, do the following:

1. Restart the VM.
2. At the GRUB menu, press e to edit the grub command.

3. On the next screen, on the gfxmode line, change $linux_gfx_mode to text so the line reads:

   gfxmode text
4. Press Ctrl-x or F10 to boot the guest operating system.

5. To update the setting so it persists for each boot cycle, edit the /boot/grub/grub.cfg file and change the gfxmode parameter to text so the line reads:

   set gfxmode=text
6. Save the /boot/grub/grub.cfg file.

To change the terminal type in a Linux-based VM if the console screen is unreadable

By default, the Linux operating system sets the TERM variable to vt100-nav, which is not properly supported by the vncterm program, the basis for the VM console. If you use anything other than the command line, the screen becomes unreadable. To resolve this issue, change the terminal type in the Linux guest operating system:

1. Open the inittab file in the guest operating system.
2. In the following line, replace vt100-nav with vt100 by deleting -nav at the end of the line. The updated line appears as follows:
   

   # Run gettys in standard runlevels co:2345:respawn:/sbin/agetty xvc0 9600 vt100

3. Save the inittab file.
