Opening a Virtual Machine Console Session
Open a virtual machine (VM) console session to display the console of the guest operating system running in the VM.
The following procedure describes how to open a VM console session in the everRun Availability Console, but you can also use a remote desktop application for this purpose.
To open a VM console session
- On the Virtual Machines page, select a VM.
- Ensure that the VM is in a running state.
-
Click Console (
) in the bottom panel.
To resolve an issue where the VM console window does not open
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 in the everRun Availability Console 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:
- Restart the VM in the everRun Availability Console.
- At the GRUB menu, press e to edit the grub command.
-
On the next screen, on the gfxmode line, change $linux_gfx_mode to text so the line reads:
gfxmode text - Press Ctrl-x or F10 to boot the guest operating system.
-
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 - 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 in everRun Availability 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:
- Open the
inittabfile in the guest operating system. -
In the following line, replace
vt100-navwithvt100by deleting-navat the end of the line. The updated line appears as follows:# Run gettys in standard runlevels co:2345:respawn:/sbin/agetty xvc0 9600 vt100 - Save the inittab file.
