StratoVirt是一个开源的VMM（虚拟机管理器），旨在执行下一代虚拟化 StratoVirt 基于 Rust 编程语言

# Hydropper： Hydropper is a lightweight test framework based on pytest. It encapsulates virtualization-related test atoms and is used for stratovirt black-box tests.Hydropper has provided some testcases for lightweight virtualization and standard virtualization to help Developers find and locate Stratovirt problems. ## How to start ### Preparation 1. Ensure that python3 has been installed on your openEuler system. 2. The requirements.txt file contains the Python3 dependency package. - pytest>5.0.0 - aexpect>1.5.0 - retrying You can install these packages by running the following commands: ```sh $ pip3 install -r requirements.txt ``` 3. Network dependency package: ```sh $ yum install nmap $ yum install iperf3 $ yum install bridge-utils ``` 4. Network configuration（template） ```sh brctl addbr strato_br0 ip link set strato_br0 up ip address add 1.1.1.1 dev strato_br0 ``` 5. For details about how to build a test image, see docs/IMAGE_BUILD.md. ### Parameter configuration Set parameters and corresponding paths in the config/config.ini. Generally, the kernel and rootfs must be configured for test cases. ```ini [env.params] ... VM_USERNAME = <usrname> VM_PASSWORD = <passwd> ... [stratovirt.params] ... STRATOVIRT_VMLINUX = /path/to/kernel STRATOVIRT_ROOTFS = /path/to/rootfs ... ``` Configure IP_PREFIX and IP_3RD in the "config.ini" file, which indicate the first 24 bits of the VM IPv4 address, The last 8 bits are automatically configured by the hydropper. Note that the VM and the host must be in the same network segment. ```ini [network.params] # such as 'IP_PREFIX.xxx.xxx' IP_PREFIX = 1.1 # such as 'xxx.xxx.IP_3RD.xxx' IP_3RD = 1 ``` ### Run testcases You can run the following commands in the hydroper directory to execute cases: ```sh # Run all cases $ pytest # Run all cases with the keyword microvm $ pytest -k microvm # Run all cases in test_microvm_cmdline.py $ pytest testcases/microvm/functional/test_microvm_cmdline.py # Run test_microvm_without_daemonize $ pytest testcases/microvm/functional/test_microvm_cmdline.py::test_microvm_without_daemonize ``` ### Add new testcases Add customized cases to the microvm directory under testcases.You can add a python file or add a function to an existing python file.The file name and function name must be in the format of test_*. ```python test_microvm_xxx.py def test_microvm_xxx() ``` We have preset some virtual machine objects. You can test the virtual machine by generating their instances： ```python def test_microvm_xxx(microvm): test_vm = microvm test_vm.launch() ``` In addition, Fixture is useful to write testcases.You can use Fixture in the following ways: ```python # Mark the tag to system @pytest.mark.system def test_microvm_xxx(microvm): test_vm = microvm test_vm.launch() ``` Now you can use the pytest -m system command to run all the "system" cases. You can use the basic_config() function to configure VM parameters： ```python # Configure four vCPUs and 4 GB memory for the VM. def test_microvm_xxx(microvm): test_vm = microvm test_vm.basic_config(vcpu_count=4, mem_size='4G') test_vm.launch() ``` ### Log - pytest default log path: /var/log/pytest.log - stratovirt default log path: /var/log/stratovirt
