Indeed. It looks like libxl even doesn't allow custom stubdom path - always
uses hardcoded default. libxl_dm.c:
stubdom_state->pv_kernel.path
= libxl__abs_path(gc, "ioemu-stubdom.gz",
libxl__xenfirmwaredir_path());
stubdom_state->pv_cmdline = libxl__sprintf(gc, " -d %d", guest_domid);
stubdom_state->pv_ramdisk.path = "";
So it does. FWIW given libxl allows an override for the process type of
qemu I can't think why we wouldn't allow an override here too.
IMO it is much more useful to specify device model type (qemu
upstream, qemu
traditional, qemu traditional in stubdom) than explicit qemu path,
I agree. Users should not generally need to care about paths to things.
