[PATCH libvirt-dbus 0/2] Introduce libivirt-dbus systemd unit
by Katerina Koukiou 01 Sep '20

01 Sep '20

For distributions that are using systemd introduce a libvirt-dbus.service and have 'libvirt' group as supplementary group for the spawned libvirt-dbus process. This will allow ubuntu users (SocketMode is 0660 in newer ubuntu), to use system connection without extra configuration.

[GSoC] Take migration in Salt virt module to the next level
by Radostin Stoyanov 01 Sep '20

01 Sep '20

Hello again libvirt community! This summer, I once again worked on a GSoC project with libvirt. This time, the goal of my project was to improve the libvirt integration with SaltStack and, in particular, the support for VM migration. SaltStack is an incredibly valuable tool that helps with automation and infrastructure management. This is accomplished with master/minion topology where a master acts as a central control bus for the clients (minions), and the minions connect back to the master. The Salt virt module provides support for core cloud operations such as VM lifecycle management, including VM migration, by allowing minions to connect with libvirt virtualization host. The Salt virt.migrate interface allows users to migrate a VM from one host to another. However, the implementation of this function used to be based on the virsh command-line tool (instead of the libvirt Python API bindings), which had resulted in an increased code complexity (e.g., string concatenation, invoking Popen.subprocess, etc) and had a limited number of migration options exposed to users. My project was roughly separated into three phases. The aim of the first phase was to improve the test coverage of the virt module by increasing the number of integration tests (i.e., before applying any major code changes). However, SaltStack is designed to run on different platforms, and it has been extended over the years to support many applications and tools. Consequently, the SaltStack test suite has grown in complexity and number of dependencies as well. As a result, not all of them (e.g., libvirt and qemu) are available in the Jenkins CI environment. In addition, our goal was to only be able to effectively test VM lifecycle management features (start, destroy, list, etc.) but also to test VM migration. To achieve this we packaged libvirt, qemu, and all required SaltStack minion dependencies in a container image that allows us to spawn multiple virtualization host instances on a single machine (with low virtualization overhead). In the second phase of the project, now with a test environment in place, we were able to refactor the virt.migrate implementation to utilize the Python bindings of libvirt and add support for additional migration options (described in the “What's new?” section below). The third phase was primarily focused on refining the set patches, resolving merge conflicts with upstream changes or other related PRs. One of the major challenges was to revisit the set of tests to make them compatible with pytest as well to collaborate with the SaltStack community to ensure that all proposed changes will be easy to maintain in the future. Contributions ============ Although the development work was done in several iterations, with code reviews on regular basis, the final result was consolidated in a single GitHub pull request: https://github.com/saltstack/salt/pull/57947 What’s new? =========== https://docs.saltstack.com/en/master/ref/modules/all/salt.modules.virt.html… The virt.migrate interface of SaltStack has been extended to support target URI format: $ salt src virt.migrate guest qemu+ssh://dst/system $ salt src virt.migrate guest qemu+tcp://dst/system $ salt src virt.migrate guest qemu+tls://dst/system with preserved backward compatibility: $ salt src virt.migrate guest dst $ salt src virt.migrate guest dst True Support for the following migration options was introduced: Disable live migration $ salt src virt.migrate guest qemu+ssh://dst/system live=False Leave the migrated VM transient on destination host $ salt src virt.migrate guest qemu+ssh://dst/system persistent=False Leave the domain defined on the source host $ salt src virt.migrate guest qemu+ssh://dst/system undefinesource=False Offline migration $ salt src virt.migrate guest qemu+ssh://dst/system offline=False Set maximum bandwidth (in MiB/s) $ salt src virt.migrate guest qemu+tls://dst/system max_bandwidth=10 Set maximum tolerable downtime for live-migration (i.e. a number of milliseconds the VM is allowed to be down at the end of live migration) $ salt src virt.migrate guest qemu+tls://dst/system max_downtime=100 Set a number of parallel network connections for live migration $ salt src virt.migrate guest qemu+tls://dst/system parallel_connections=10 Live migration with enabled compression $ salt src virt.migrate guest qemu+tls://dst/system \ compressed=True \ comp_methods=mt \ comp_mt_level=5 \ comp_mt_threads=4 \ comp_mt_dthreads=4 $ salt src virt.migrate guest qemu+tls://dst/system \ compressed=True \ comp_methods=xbzrle \ comp_xbzrle_cache=1024 Migrate non-shared storage (Full disk copy) $ salt src virt.migrate guest qemu+tls://dst/system copy_storage=all (Incremental copy) $ salt src virt.migrate guest qemu+tls://dst/system copy_storage=inc Using post-copy migration $ salt src virt.migrate guest qemu+tls://dst/system postcopy=True $ salt src virt.migrate_start_postcopy guest Using post-copy migration with bandwidth limit (MiB/s) $ salt src virt.migrate guest qemu+tls://dst/system \ postcopy=True \ postcopy_bandwidth=1 $ salt src virt.migrate_start_postcopy guest Acknowledgments =============== I would like to sincerely thank all those who provided me with their time, assistance, and guidance during the course of this project, for which I am enormously grateful. I would like to thank Cedric Bosdonnat (cbosdo), Pedro Algarvio (s0undt3ch), Wayne Werner (waynew), Charles McMarrow (cmcmarrow) and Daniel Wozniak (dwoz) who offered a huge amount of support, expertise, guidance and code reviews. I would also like to thank Michal Privoznik (mprivozn), Martin Kletzander (mkletzan) and the rest of the libvirt and SaltStack communities who have been extremely supportive. Best wishes, Radostin

[GSoC PATCH 0/9] Libvirt Driver for Jailhouse Hypervisor
by Prakhar Bansal 31 Aug '20

31 Aug '20

From: Prakhar Bansal <itsprakhar(a)gmail.com> My name is Prakhar Bansal and I am a graduate student at Iowa State University, Iowa, USA. During the last 3 months of GSoC'20, I worked on adding support for a new driver for the Jailhouse hypervisor. Following is the implementation of various Libvirt driver callbacks in the driver pertaining to hypervisor connection and domain lifecycle. This driver is a state driver which initializes the driver state during the libvirtd daemon start and uses it during many connection lifecycles. Please check the design doc for the driver(check the project's link at GSOC-2020 website) for more details.

[PATCH] qemu: Validate memory hotplug in domainValidateCallback instead of cmd line generator
by Michal Privoznik 31 Aug '20

31 Aug '20

When editing a domain with hotplug enabled, I removed the only NUMA node it had and got no error. I got the error later though, when starting the domain. This is not as user friendly as it can be. Move the validation call out from command line generator and into domain validator (which is called prior to starting cmd line generation anyway). When doing this, I had to remove memory-hotplug-nonuma xml2xml test case because there is no way the test case can succeed, obviously.

[PATCH] virmigraiton: `qemuMigrationJobPhase` transformed for more generic use

`qemuMigrationJobPhase` was transformed into `virMigrationJobPhase` and a common util file `virmigration` was created to store its defination. This is one of the initial steps we are taking towards making more and more code hypervisor agnostic. And this shall be followed by transformation of similar structs in the future.

[libvirt PATCH] meson: Use @BASENAME@ more

31 Aug '20

This patch takes care of just the obvious cases: there are many more situations where the data we pass to configure_file() could likely be obtained in a more effective way, but we can address the low-hanging fruits as a first approximation.
