I don't think it is expected that this line (even if uncommented) would
do anything for Windows unless you have a PV FB frontend driver, which
I'm fairly certain doesn't exist. So I think:

is entirely expected.

The vfb line is for use with PV guests which have a PVFB driver.

You just need regular gdb not gdbsx.

Run it as eg.g.
        gdb --args xl cd-eject <aprams>

then when it crashes type "bt".

I tested this with Linux HVM. I don't have any Windows domUs.

Does this work without GPLPV drivers? The CDROM device should be
emulated even if those are installed anyway.

Ian.
