Subject: [Qemu-devel] '-usb' regressed by 49d2e648 ("machine: remove qemu_machine_opts global list")

Message-ID: <5499E8D4.4010903@redhat.com> (raw)

Apologies if this problem is known. After building qemu at ab0302ee:

$ qemu-system-x86_64 -usb

qemu-system-x86_64: util/qemu-option.c:387: qemu_opt_get_bool_helper: Assertion `opt->desc && opt->desc->type == QEMU_OPT_BOOL' failed.

The stack is

Bisection fingers 49d2e648.

This is very visible with libvirt.

Thanks
