This article from the technical community titled “Does Xinchuang Virtualization Horizontal Expansion Host Need to Upgrade Virtualization Software Version?” discusses whether to upgrade the virtualization software version when expanding the Xinchuang virtualization horizontally. This issue may be related to the product brand, and specific references can be made.
Viewpoint 1
It is recommended to prioritize stability. The manufacturer insists on upgrading the virtualization software version for a reason, so an upgrade is advised.
Currently, mainstream Xinchuang virtualization products do not require it. The horizontal expansion of the host is a common feature of virtualization. Manufacturers should optimize it so that one upgrade can solve the issue. Otherwise, with the Xinchuang transformation, horizontal expansion of the host will be frequent, and continuous upgrades will put significant pressure on operations and maintenance.
1. If the expansion host must upgrade the virtualization software version, the manufacturer should provide a specific response and clarify the reasons, then see if it is acceptable. This also helps to rule out the possibility of security risks existing even without an upgrade. Normally, expansion is expansion, and upgrade is upgrade; they should not be confused.
2. It is still recommended for manufacturers’ virtualization products to upgrade while ensuring the stability of the production environment. On one hand, upgrades fix bugs on the virtualization platform, and on the other hand, they can enhance security and fix vulnerabilities at the underlying level. Especially with the increasing demands for security, upgrades should be made; otherwise, it will be harder to advance work later if the version differences are too large.
Regarding high availability, we have encountered the issue of whether to upgrade the virtualization software version when expanding the Xinchuang virtualization horizontally before. The situation at that time was that the microcode version of the new hardware was too new, causing the old version of the virtualization software to be unsupported, and ultimately, the only solution was to upgrade. If it is another situation, within my knowledge, for mainstream domestic virtualization software, the expansion host generally does not require a version upgrade of the virtualization software. This also indicates that in most cases, users can directly add new hosts to the existing virtualization environment without worrying about compatibility issues or additional software update costs.
In general, whether Xinchuang virtualization horizontal expansion hosts can be expanded without upgrading the version depends on the specific virtualization product and technical implementation.
Some Xinchuang virtualization products are designed to support horizontal expansion without upgrading the version, while others may require an upgrade of the virtualization software version due to technical architecture and functional implementation.
For cases where the expansion host must upgrade the virtualization software version, it may be due to specific limitations or requirements in the architectural design or functional implementation of the Xinchuang virtualization product being used, necessitating a software version upgrade to ensure system stability, compatibility, or performance requirements during host expansion.
This may bring some challenges to the system operation and maintenance and upgrade work for enterprises, such as increasing upgrade costs and potentially affecting the normal uptime of the system.
If you want to avoid this situation, consider choosing Xinchuang virtualization products that support more flexible expansion methods in their design, or communicate with the virtualization product vendors to understand if there are other solutions or optimizations to reduce the impact of version upgrades on expansion work.
Additionally, when planning and implementing Xinchuang virtualization projects, it is essential to fully consider the system’s scalability and upgrade requirements, and to prepare the technical selection and solution design in advance.
