libvirt TCK

a project by jfehlig

The libvirt TCK provides a framework for performing testing of the integration between libvirt drivers, the underlying virt hypervisor technology, related operating system services and system configuration. The idea (and name) is motivated by the Java TCK.

Warp speed for virtualization CI testing

a project by jfehlig

The virtualization team's automated testing has a long history. It was born in the old Novell Integration Test framework. The virtualization lab ran an instance of this framework for many years. Over time, those who knew the framework left the company, taking their knowledge and leaving little documentation behind. As our testing needs increased, we found the old framework insufficient, but saw little value in improving it given the available open source CI frameworks.

Protect disk devices from concurrent use in the libvirt libxl hypervisor driver

a project by jfehlig

The libvirt qemu hypervisor driver has long supported protecting disk devices from concurrent use via libvirt's lock manager interface. Xen used to support the same functionality in the old xend toolstack, but dropped support in the new libxl toolstack. The Xen community decided, rightly so, that this functionality is best provided by a higher-level management tool, e.g. libvirt.

Native Xen support for RADOS Block devices

a project by jfehlig

libvirt+Xen should support the qdisk (qemu) rbd backend, providing native access to block devices hosted on Ceph clusters. Adding this support to the libvirt+Xen toolstack will also improve interoperability with SUSE Enterprise Storage.

Improve openvswitch+libvirt+Xen

a project by jfehlig

openvswitch is used by cloud infrastructure (e.g. OpenStack) and software defined networking stacks, often in conjunction with KVM and Xen compute resources. When creating workloads on KVM compute resources, orchestration services can specify the openvswitch interfaceid and port-profile of the workload's virtual interface(s). E.g. orchestration can create workload configuration containing

Add more unit tests for libvirt

a project by jfehlig

I wanted to work on something test related this hackweek since we always need more automated testing of our virtualization-related packages. There are many possible test-related topics, but I think a good addition would be more unit tests that are run during build time, e.g. during 'make check'. Additional tests of this nature would then be run by upstream developers and the various distro CI setups, exposing the tests to more environments than would typically be available within SUSE.

Create a tool to generate vCPU/vNUMA topology for virtual machines

a project by jfehlig

Most large workloads such as SAP HANA require special, highly optimized configuration to run in a virtual machine. Virtual resources such as memory and CPU must be carefully configured to ensure optimum performance of the virtual machine workload. Default VM configuration created by tools such as virt-install are not optimized and often result in poor performance of large workloads due to memory access latencies and incorrect/incomplete information available to the VM's task scheduler.

Investigate and improve Brewtarget

a project by jfehlig

Brewtarget is an open source brewing software, similar to the commercial product BeerSmith. For hackweek I'd like to investigate the capabilities of Brewtarget and perhaps add some features/improvements for my use case.

Run VMs in CaaSP 4 cluster with SUSE-powered kubevirt

a project by jfehlig

This project aims to run VMs in a CaaSP 4 cluster using kubevirt and a libvirt+qemu container (aka compute container) based on SLES15 SP1/2. Compute containers based on openSUSE Leap15.1 and SLES15 SP1 already available in registry.opensuse.org and registry.suse.com respectively. VMs can be deployed to the cluster but there are several functional problems that need investigating, e.g. accessing the VM's serial and VNC consoles, proper network access, etc.

KubeVirt related stuff

a project by jfehlig

Project Description

Update the physical KubeVirt+Kubernetes test cluster in Provo from SLES15 SP2 and CaaSP to SLES15 SP3 and Rancher's k3s. This will allow us to easily experiment and test Harvester.

Experiment with Confidential Containers

a project by jfehlig

Description

libkrun-sev allows running confidential workloads in a lightweight VM within a container. I'd like to experiment with libkrun-sev, the oci2cw image tool, and attestation using reference-kbs.
