How to run kvm/qemu on a virtual terminal with kms enabled

I deduce from the kvm howtos that this should actually work with sdl and a framebuffer, but I can't get it going.
Doing kvm -cdrom tinycore-current.iso with normal user account on a virtual terminal gives:



kvm: pci_add_option_rom: failed to find romfile "pxe-rtl8139.bin"

init kbd.

init mouse failed.

Could not initialize SDL(Unable to open mouse) - exiting

While it works flawlessly under X.

Running it with sudo prepended crashes display and keyboard.

So what can I do?

As the error message states, SDL cannot access the mouse. If this error doesn't show as root (using sudo), this is probably a permissions problem. You should check the permissions of /dev/input/mice.

It is likely that once the mouse problem is fixed it will show the same behaviour as when run using sudo. It might not be worth the trouble to try getting it running with framebuffer. Without knowing the details I'd say using X might a better solution.
