Both OVMF and RHF firmwares triggered an error when O_DIRECT was used because they didn't align the buffers to the block sector size. In order to prevent regressions, we're adding a new test validating the VM can properly boot when the OS disk is opened with O_DIRECT and booted from the rust-hypervisor-fw.
