[PATCH] domain_interface: Fix build on FreeBSD
by Michal Privoznik 15 Apr '24

In one of my recent commits I've chopped just too much and moved a variable declaration into a function not realizing it's still used on FreeBSD. Bring it back but only for the FreeBSD case.

[PATCH 0/2] A couple of fixes for non-standard builddir
by Michal Privoznik 15 Apr '24

15 Apr '24

The other day somebody on #virt complained about test suite failing on a fresh checkout. Turned out, our mocking and some bash scripts are not prepared for a case when there's a space in builddir path. After these, there are still some tests failing, but my brain is too small to fix them: 1) Somehow, $builddir/docs/html/libvirt-libvirt-common.html (and friends) are generated into $builddir/html/libvirt-libvirt-common.html and I can't figure out why. This means, check-html and check-html-references tests are failing. 2) There's some problem with po_check as it fails to find generated sources (like src/remote/remote_client_bodies.h). I've taken look into our syntax-check.mk but I have no idea what's wrong nor how to properly escape paths in Makefile.

VHPC'24 - 19th Virtualization in High-Performance Cloud Computing Workshop - Call for Papers
by Remo Andreoli 13 Apr '24

13 Apr '24

VHPC'24<https://vhpc.org/>: August 26th-27th, Madrid, Spain, co-located with Euro-Par 2024. Papers due: May 6th. The Workshop on Virtualization in High-Performance Cloud Computing (VHPC<https://vhpc.org>) aims to bring together researchers and industrial practitioners facing the challenges posed by virtualization in HPC/Cloud scenarios in order to foster discussion, collaboration, mutual exchange of knowledge and experience, enabling research to ultimately provide novel solutions for virtualized computing systems. The workshop features paper presentations, discussion sessions, and lightning talks. Accepted papers will be published in a Springer LNCS volume. Focus Topics This year, we are calling the timely topic of virtualization in support of high-memory LLM training workloads including, but not limited to: * GPU hypervisor memory virtualization * Flat CPU/GPU memory page tables/TLB * Storage/filesystem to virtual memory mapped approaches * Distributed memory virtualization * Memory compression and reduction techniques * Out-of-core training algorithms * Memory-efficient allocation and data formats * Benchmarking and profiling tools * Real-world examples and applications of virtualization techniques in LLM training scenarios In addition to the regular topic areas of HPC virtualization: design/architecture, management, performance management, modeling and configuration/tooling: * Container Platforms (Kubernetes, Docker, Nitro/Firecracker, …) and Unikernel Frameworks * Composable Lightweight Application Components and Lambda / Function-as-a-Service Paradigms * Latency Control, Warm/Cold-start issues and Data/Container Placement in Heterogeneous Environments * Energy-efficiency and Service Orchestration in Virtualized Cloud & HPC Infrastructures The workshop will be composed of 20 min paper presentations, each followed by 10 min discussion sessions, plus lightning talks that are limited to 5 minutes. Presentations may be accompanied by interactive demonstrations. For more information and detailed paper submission instructions, refer to the VHPC'24 webpage<https://vhpc.org/>. Important Dates (AoE) * May 6th, 2024: Paper submission deadline (Springer LNCS) * Jun 20th, 2024: Acceptance notification * Jul 1st, 2024: Camera-ready version due * Aug 26th-27th, 2024: Workshop Day Workshop Chair * Michael Alexander (chair), University of Vienna, Austria * Anastassios Nanos (co-chair), Nubificus Ltd., UK * Tommaso Cucinotta (co-chair), Scuola Superiore Sant'Anna, Italy Publicity Chair * Remo Andreoli, Scuola Superiore Sant'Anna, Italy General Information The workshop will be held in conjunction with the International European Conference on Parallel and Distributed Computing (Euro-Par 2024)<https://2024.euro-par.org>, on Aug 26th-27th, 2024, in Madrid, Spain.

[PATCH] vbox: Drop needless g_new0(..., 0) in vbox_snapshot_conf.c
by Michal Privoznik 12 Apr '24

12 Apr '24

clang on Fedora started to complain about some calls to g_new0() we're making in vbox_snapshot_conf.c. Specifically, we're passing zero as number of elements to allocate. And while usually SA tools are not clever, in this specific case clang is right. There are three cases where such call is made, but all of them later use VIR_EXPAND_N() to allocate more memory (if needed). But VIR_EXPAND_N() accepts a variable set to NULL happily. Therefore, just drop those three calls to g_new0(..., 0) and let VIR_EXPAND_N() allocate memory.
