KVM-test: Add a new bonding subtest From: Amos Kong <[email protected]>
In this test, execute bonding_setup.py to setup bonding of guest, do basic transfer test, and repeatedly put down/up interfaces by set_link for testing high availability. Changes from v1: - Add file transfer test - Setup bonding by serial - Fix bonding_setup.py Changes from v2: - Drop ping test - Assign mac of nic1 to bond0 - Do some basic test before testing high availability - Repeatedly down/up link by monitor cmd Changes from v3: - Fix indentation issue in config file - Return 1 when not assign macaddr to bonding_setup.py Signed-off-by: Feng Yang <[email protected]> Signed-off-by: Amos Kong <[email protected]> --- client/tests/kvm/scripts/bonding_setup.py | 37 +++++++++++++++++++ client/tests/kvm/tests/nic_bonding.py | 57 +++++++++++++++++++++++++++++ client/tests/kvm/tests_base.cfg.sample | 11 ++++++ 3 files changed, 105 insertions(+), 0 deletions(-) create mode 100644 client/tests/kvm/scripts/bonding_setup.py create mode 100644 client/tests/kvm/tests/nic_bonding.py diff --git a/client/tests/kvm/scripts/bonding_setup.py b/client/tests/kvm/scripts/bonding_setup.py new file mode 100644 index 0000000..f2d4be9 --- /dev/null +++ b/client/tests/kvm/scripts/bonding_setup.py @@ -0,0 +1,37 @@ +import os, re, commands, sys +"""This script is used to setup bonding, macaddr of bond0 should be assigned by +argv1""" + +if len(sys.argv) != 2: + sys.exit(1) +mac = sys.argv[1] +eth_nums = 0 +ifconfig_output = commands.getoutput("ifconfig") +re_eth = "eth[0-9]*" +for ename in re.findall(re_eth, ifconfig_output): + eth_config_file = "/etc/sysconfig/network-scripts/ifcfg-%s" % ename + eth_config = """DEVICE=%s +USERCTL=no +ONBOOT=yes +MASTER=bond0 +SLAVE=yes +BOOTPROTO=none +""" % ename + f = file(eth_config_file,'w') + f.write(eth_config) + f.close() + +bonding_config_file = "/etc/sysconfig/network-scripts/ifcfg-bond0" +bond_config = """DEVICE=bond0 +BOOTPROTO=dhcp +NETWORKING_IPV6=no +ONBOOT=yes +USERCTL=no +MACADDR=%s +""" % mac +f = file(bonding_config_file, "w") +f.write(bond_config) +f.close() +os.system("modprobe bonding") +os.system("service NetworkManager stop") +os.system("service network restart") diff --git a/client/tests/kvm/tests/nic_bonding.py b/client/tests/kvm/tests/nic_bonding.py new file mode 100644 index 0000000..3b1fc8c --- /dev/null +++ b/client/tests/kvm/tests/nic_bonding.py @@ -0,0 +1,57 @@ +import logging, time, threading +from autotest_lib.client.common_lib import error +from tests import file_transfer +import kvm_test_utils, kvm_utils + +def run_nic_bonding(test, params, env): + """ + Nic bonding test in guest. + + 1) Start guest with four nic models. + 2) Setup bond0 in guest by script bonding_setup.py. + 3) Execute file transfer test between guest and host. + 4) Repeatedly put down/up interfaces by set_link + 5) Execute file transfer test between guest and host. + + @param test: Kvm test object. + @param params: Dictionary with the test parameters. + @param env: Dictionary with test environment. + """ + def control_link_loop(vm, termination_event): + logging.info("Repeatedly put down/up interfaces by set_link") + while True: + for i in range(len(params.get("nics").split())): + linkname = "%s.%s" % (params.get("nic_model"), i) + cmd = "set_link %s down" % linkname + vm.monitor.cmd(cmd) + time.sleep(1) + cmd = "set_link %s up" % linkname + vm.monitor.cmd(cmd) + if termination_event.isSet(): + break + + timeout = int(params.get("login_timeout", 1200)) + vm = kvm_test_utils.get_living_vm(env, params.get("main_vm")) + session_serial = kvm_test_utils.wait_for_login(vm, 0, timeout, 0, 2, + serial=True) + script_path = kvm_utils.get_path(test.bindir, "scripts/bonding_setup.py") + vm.copy_files_to(script_path, "/tmp/bonding_setup.py") + cmd = "python /tmp/bonding_setup.py %s" % vm.get_mac_address() + s, o = session_serial.get_command_status_output(cmd) + if s != 0: + logging.debug(o) + raise error.TestFail("Fail to setup bonding") + + termination_event = threading.Event() + t = threading.Thread(target=control_link_loop, + args=(vm, termination_event)) + try: + logging.info("Do some basic test before testing high availability") + file_transfer.run_file_transfer(test, params, env) + t.start() + logging.info("Do file transfer testing") + file_transfer.run_file_transfer(test, params, env) + finally: + termination_event.set() + t.join(10) + session_serial.close() diff --git a/client/tests/kvm/tests_base.cfg.sample b/client/tests/kvm/tests_base.cfg.sample index 2ae7f78..2104af6 100644 --- a/client/tests/kvm/tests_base.cfg.sample +++ b/client/tests/kvm/tests_base.cfg.sample @@ -541,6 +541,17 @@ variants: filesize = 512 nic_mode = tap + - nic_bonding: + type = nic_bonding + nics += ' nic2 nic3 nic4' + image_snapshot = yes + serial_login = yes + test_timeout = 1000 + filesize = 4000 + transfer_timeout = 1000 + transfer_type = remote + kill_vm = yes + - physical_resources_check: install setup unattended_install.cdrom type = physical_resources_check catch_uuid_cmd = dmidecode | awk -F: '/UUID/ {print $2}' _______________________________________________ Autotest mailing list [email protected] http://test.kernel.org/cgi-bin/mailman/listinfo/autotest
