I'm trying to install CentOS Stream 9 on VirtualBox from my underlying Arch Linux system. After getting the message that "the virtual machine reports that the guest OS does not support mouse pointer integration in the current virtual mode", I thus choose to capture the mouse, but this doesn't work. I can't even select my language (US English) with a click, neither left click or a right click menu. Hitting enter also does nothing. I can enter click mode and move up and down selections with my arrow keys in the GUI, and I can select with the enter key to initially choose to "install CentOS Stream" in the virtual machine, but I can't select anything once I'm in the GUI.

UPDATE: When I start the VM, the tab under "input" for "mouse pointer integration" is greyed out, so I can't select or unselect it.

UPDATE: I fixed it: It turns out going shutting down the machine, going into "Settings" and changing the pointing device to "USB Tablet" then restarting it with mouse pointer integration on works.
