I intend to create opensuse docker images ready for mining cryptocurrencies (cpu based algorithms like cryptonight as a first try), and if time permits, I will also try to deploy the containers using kubernetes.

While there are plenty of benchmarks that compare different IO multiplexing techniques such as epoll vs poll/select, there's really nothing out there that particularly measures epoll system call latencies under different scenarios. Design and implement a series of performance benchmarks for this call under the 'perf bench' framework.

PVH domains are a new guest type supported by Xen being as lightweight as possible (e.g. no emulation of legacy devices via qemu) while taking advantage of the hardware virtualization features of the x86 processor. As there is no BIOS for a PVH domain booting is a little bit different than for pure hardware virtualized guests. To be able to start such a guest a little shim is needed to gather some information about the environment (especially memory layout) before the standard kernel boot path can be entered. By using a boot loader like grub2 this shim can be avoided as the memory information is already known by grub2 and stored into the so called zeropage according to the multiboot protocol.

The YaST2 Network module manages network configuration including device configuration, DNS, Routing etc.. The current code is not very object oriented and in many cases there is not a good separation between the business logic and the presentation. The API is also not very clear an many people get confused for example between NetworkInterfaces (class that handles with the ifcfg-files and reside in yast-yast2) and LanItems.
