=== This is the QEMU I/O test suite === * Intro This package contains a simple test suite for the I/O layer of qemu. It does not require a guest, but only the qemu, qemu-img and qemu-io binaries. This does limit it to exercise the low-level I/O path only but no actual block drivers like ide, scsi or virtio. * Usage Just run ./check to run all tests for the raw image format, or ./check -qcow2 to test the qcow2 image format. The output of ./check -h explains additional options to test further image formats or I/O methods. * Feedback and patches Please send improvements to the test suite, general feedback or just reports of failing tests cases to qemu-devel@nongnu.org with a CC: to qemu-block@nongnu.org.
