On June 14 , at the KVM Forum , the world's top virtualization technology summit , the 2023 Global Enterprise KVM Open Source Contribution List was officially released. Tencent Cloud has become the only cloud vendor in China that has been shortlisted for seven consecutive years.
As the key underlying technology of cloud computing, cloud vendors need to use KVM to virtualize physical machines and provide pooled computing power in the cloud. As the most important and authoritative conference in the KVM virtualization community. This year's KVM Forum conference was held in the Czech Republic. At the conference, the global enterprise KVM open source contribution list was released again to measure the technical strength and open source contribution of enterprises in the KVM field.
As the only Chinese company that has entered the list for 7 consecutive years and has the highest contribution value, Tencent Cloud has contributed a total of 30 patches this year , which is the only " core breakthrough " of a Chinese company . In the past seven years, Tencent Cloud has contributed a total of 310 patches and 11 core breakthroughs .
Tencent Cloud's PMU improvements solution was rated as KVM's annual core breakthrough
This year, Tencent Cloud's self-developed PMU improvements solution was rated as KVM's annual core breakthrough. This solution successfully implements the support for PerfMonV2 on the virtual machine , which not only reduces the overhead of virtualization, but also improves the accuracy when multiple virtual machines are used in parallel.
Today, the core framework of the program has been contributed to the open source community, and has been widely recognized and tested by the industry. With the help of Tencent Cloud's self-developed virtualization technology, developers can now use code-level hardware performance data to deeply explore business performance changes, identify and solve performance bottlenecks, thereby improving overall operating efficiency and reducing computing costs.
At the 2023 KVM Forum , the Tencent Cloud team also delivered a speech titled " Live control of (most) CPU features via hybrid vCPU model ", sharing that when a virtual machine is migrated from an old CPU model host to a new one, it supports Mixed vCPU models can realize real-time feature switching or fallback on the cloud, so as to make full use of the functions of the new host.
This solution, widely recognized in the virtualization community, helps optimize virtual machine performance and overcome potential hurdles in the migration process.
In addition, Tencent Cloud also created cube lightweight virtualization products based on cloud-hypervisor . Provide a high-performance, low-overhead, and high-density operating environment for businesses. Designed a complete set of optimization solutions from host OS , virtualization, and virtual machine OS . In addition, Cube has also carried out deep optimization of the technology stack for the snapshot solution, introduced a number of key functions, and further improved the startup speed, making the virtual machine in the lightweight scenario run faster.
Through these optimizations, Cube can provide a solution with high performance and low overhead in a limited space.
As the earliest cloud computing vendor in China to embrace KVM technology, Tencent Cloud has fully adopted KVM technology supported by the open source community since 2013 ; since 2014 , Tencent Cloud cloud server CVM has been produced based on KVM technology, and began to contribute to the KVM community in the same year . Over the years, Tencent Cloud has contributed many cutting-edge technologies such as hot migration, virtualization layer consumption reduction, and lightweight virtualization technology to the open source community.
As the core module of the Linux kernel, the technological breakthrough in the field of KVM also means that Chinese companies are moving upstream in the operating system community.
The relevant person in charge of Tencent Cloud said that in the future, Tencent Cloud will continue to embrace changes in the field of virtualization. On the one hand, it will solve various challenges Tencent Cloud encounters online through continuous innovation and feed back the output to the community. On the other hand, it will explore cloud computing. To develop new technologies in the field, do a good job in the pre-research and accumulation of cutting-edge technologies, and unswervingly continue to make contributions to the virtualization open source community.
