KVM-Autotest/TODO

KVM-Autotest To-Do list

Framework

• Verify MD5 sum of ISO image before starting a VM [Michael] [DONE]
• Enable multiple user controlled port redirections (with -redir) [Michael] [DONE]
• Implement functions to translate VM ports and addresses (e.g. VM.get_port(), VM.get_address()) [Michael] [DONE]
• Support TAP networking with a user specified MAC address for each NIC [Michael]
• Add display parameter to enable user control of the QEMU display method (VNC/SDL/nographic) [Michael] [DONE]
• Implement VM.clone() -- to be used by tests that need to add new VMs by themselves [Michael]
• kickstart installation support
• kvm-autotest auto resolve qemu-kvm backtraces
• Make sure ppm_utils.image_crop() handles bad input properly [Michael] [DONE]
• Enable tests to modify a VM's params (while it's down) [Michael]
• Make tests shorter by using small utility functions that fail a test and display a failure message [Michael]
• Improve the stepmaker data naming system (e.g. name PPM files according to their MD5 sums) [Michael] [DONE]
• Redirect guest monitor to serial and capture guest error messages written to console. Log the errors and also scan for specific problems (e.g. oops)
• Support an "expected to fail" param (at least in our html report)
• Log a gdb-backtrace for tests (executables) which generate a core dump file.
• Enable "guest-load" for a VMs before/while tests are running (e.g. migration of a VM, while a movie is playing on it) [Michael]
• Add support for kvm-trace.
• Fail upon indentation/white-space problems in the configuration file
• Add a way to shutdown the VMs when the whole job completes (compared to doing nothing or shutting-down after every test) [Michael]
• Implement include functionality in the config file parser [Michael] [DONE]
• Implement kvm_spawn.get_command_status_output() to make sending SSH commands easier [Michael] [DONE]
• Config file parser: enable selective modification of parameters based on regular expressions, e.g. mem.* ?= 256 [Michael]
• Support running user specified pre-job, post-job, pre-test and post-test scripts [Michael]
• Make Step Editor accept a filename command line argument [Michael] [DONE]
• When running step files, detect frozen (stuck) guests even in the presence of a blinking cursor [Michael] [DONE]
• Support running tests in parallel with multiple queues for each host [Michael]
• Automatically convert PPM images in debug dirs to PNG format to save space [Michael]
• Automatically assign a UUID to a VM (use the '-uuid' QEMU parameter). Once assigned, should be used in all dependent tests. [jasowang]
• Automatically assign a MAC address to a NIC. Once assigned, should be used in all dependent tests. [jasowang]
• Allow run_bg to track a child process's stdin and stderr even after the parent process has exited; achieved by merging run_bg with kvm_spawn [Michael] [DONE]

Tests

• Find out how to use Autotest's netperf test with guests [Yolkfull]
• If needed, write a netperf/iperf test [jasowang]
• Write a time drift test (pic/apic/pm_timer)
• Write a test which adds VMs until one of them becomes unresponsive, and records the maximum number of VMs successfully started [Yolkfull] [ALREADY DONE]
• cpu hotplug [Glauber]
• pci net hot plug [Yolkfull]
• pci block hot plug [Yolkfull]
• s3 hibernation [Gleb] [DONE]
• tap networking [jasowang]
• pxe boot * net types [jasowang]
• qcow1, qcow2, vmdk, vhd
• qcow2 internal snapshots
• Run autotest tests inside Linux guest [Michael] [ALREADY DONE]
• Further migration [jasowang]
• Multiple nics [jasowang]
• multiple disks
• ksm [jasowang, jzupka, ldoktor]
• -vga stg, nographics
• kvm unit-tests
• Add unattended guest installations (using kickstart or answer-files) [jasowang]
• kvm_install -- keep src and build directories under <kvm_autotest_root> instead of under kvm_runtest_2.
• Stable tsc test - http://people.redhat.com/mingo/time-warp-test/MINI-HOWTO
• Guest installation with pv-block device/driver (for both windows and Linux)
• savevm test [jasowang]
• Guests with large page support [jzupka, ldoktor]
• Verify SMBIOS/DMI data (UUID, for example)
• Disk serial number (for IDE, SCSI, VirtIO drives)
• Test block device cancellation path using device mapper to generate errors ( after we had a crash in de_write_dma_cb)

Misc

• Goal -- get accepted into upstream autotest
• Add docstrings to all functions that still lack them, including the ones in stepmaker.py, stepeditor.py and kvm_tests.py [Michael]
• Add module headers and docstrings [Michael]
• Document the setupssh.iso and setuptelnet.iso creation procedures in the wiki
• Rename all Windows ISOs currently used to their official MSDN names
• Move Windows-setup iso images into the windows directory. [DONE]
• Share all the stepmaker data somehow so other people can debug stepfiles
• Fill the sections "Working with step files" and "Step file creation tips" in the wiki [Michael]
• Document the kvm_install test in the "Tests" section of the wiki

Bugs

• Step Maker/Step Editor: fix the GDK MemoryError problem (do not pass gtk.gdk.pixbuf_new_from_data() a 0x0 pixmap even if a ppm file contains one) [DONE]
