Changes from v1: - use old options to add a usb disk to guest '-usbdevice disk:format=qcow2:/tmp/usbdevice.qcow2' - identify device name of new disk by '/dev/disk/by-path/' - match device with the detail output of 'lsusb -v' - create disk image by pre_cmd CC: Gerd Hoffmann Signed-off-by: Amos Kong --- client/tests/kvm/tests/usb.py | 50 ++++++++++++++++++++++++++++++++ client/tests/kvm/tests_base.cfg.sample | 9 ++++++ 2 files changed, 59 insertions(+), 0 deletions(-) create mode 100644 client/tests/kvm/tests/usb.py diff --git a/client/tests/kvm/tests/usb.py b/client/tests/kvm/tests/usb.py new file mode 100644 index 0000000..d1849de --- /dev/null +++ b/client/tests/kvm/tests/usb.py @@ -0,0 +1,50 @@ +import logging +from autotest_lib.client.common_lib import error + + +@error.context_aware +def run_usb(test, params, env): + """ + Test usb device of guest + + 1) create a image file by qemu-img + 2) boot up a guest add this file as a usb device + 3) check usb device information by execute monitor/guest command + + @param test: kvm test object + @param params: Dictionary with the test parameters + @param env: Dictionary with test environment. + """ + vm = env.get_vm(params["main_vm"]) + vm.create() + + session = vm.wait_for_login(timeout=int(params.get("login_timeout", 360))) + + output = vm.monitor.cmd("info usb") + if "Product QEMU USB MSD" not in output: + logging.debug(output) + raise error.TestFail("Could not find mass storage device") + + output = session.get_command_output("lsusb -v") + #no bus specified, default using "usb.0" for "usb-storage" + for i in ["ID 0000:0000", "Mass Storage", "SCSI", "QEMU USB HARDDRIVE"]: + if i not in output: + logging.debug(output) + raise error.TestFail("No '%s' in the output of 'lsusb -v'" % i) + + output = session.get_command_output("fdisk -l") + if params.get("fdisk_string") not in output: + logging.debug(output) + raise error.TestFail("Could not realise the usb device") + + error.context("Formating usb disk") + devname = session.get_command_output("ls /dev/disk/by-path/*|grep usb") + session.cmd("yes |mkfs %s" % devname, + timeout=int(params.get("format_timeout"))) + + error.context("Checking if exist I/O error in dmesg") + output = session.get_command_output("dmesg") + if "Buffer I/O error" in output: + logging.debug(output) + raise error.TestFail("Exists I/O error when format usb device") + session.close() diff --git a/client/tests/kvm/tests_base.cfg.sample b/client/tests/kvm/tests_base.cfg.sample index d597b52..a4e9a93 100644 --- a/client/tests/kvm/tests_base.cfg.sample +++ b/client/tests/kvm/tests_base.cfg.sample @@ -1115,6 +1115,15 @@ variants: image_snapshot = yes only Linux + - usb: install setup image_copy unattended_install.cdrom + type = usb + kill_vm = yes + format_timeout = 400 + extra_params += " -usbdevice disk:format=qcow2:/tmp/usbdevice.qcow2" + pre_command += "qemu-img create -f qcow2 /tmp/usbdevice.qcow2 10M;" + fdisk_string = "Units = cylinders of 20 * 512 = 10240 bytes" + only Linux + # NICs variants:
