You don't get an interrupt. Glancing at the run script, I see that the
ACPI driver is missing. On hardware and even Qemu it is usually required
to find out the correct GSI (global system interrupt) values. It then
overwrites the ones in the PCI config space, that are legacy PIC
interrupt numbers. Also the driver parses the MADT in order to retrieve
any interrupt overrides. Since you also seem to use the AHCI run script,
you can configure the ACPI server and the ATAPI driver in the same way
as it's done there.
