So I have installed VM and I was trying to make the screen resolution bigger and installed "sudo apt-get install virtualbox-guest-dkms" on the terminal command.

It told me to restart the VM, so i did; but then when I try to run it again, I'm getting this error message and I can't run the VM;

The specified I/O port range intruded on an existing range. There is a I/O port conflict between two device, or a device tried to register the same range twice. (VERR_IOM_IOPORT_RANGE_CONFLICT

Result Code: E_FAIL (0x80004005) Component: ConsoleWrap Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

Any help or advice would be appreciated!

Thank You


There might be settings that are not configured properly. In the virtual box, go to the settings, then to the serial ports option. You can see 4 ports , all with user defined options. In the dropdown where userdefined is displayed select the different ports(COM1,COM2,COM3,COM4) for all the 4 ports and apply. Then try starting the machine again. The message wont be coming now.
