Kernel panic when installl AlmaLinux 9.x on KVM VPS

A Vietnam VPS is a virtual server created from a physical server located in a Data Center in Vietnam and has a Vietnamese IP address. It is the top choice for websites and applications targeting users within the country, thanks to superior access speeds and extremely low latency.

Additionally, you might encounter variants like Viettel VPS, VNPT VPS, or FPT VPS. These are VPS services created from physical servers in the respective carriers' data centers, designed to serve needs for an IP from a specific carrier. Essentially, they are a form of Vietnam VPS.

Technical Working Principle

A Vietnam VPS operates on virtualization technology, which divides a powerful physical server into multiple independent virtual environments:

• Resource Virtualization: A physical server (located in Vietnam) has a virtualization software layer (a hypervisor) like KVM installed. This layer partitions the hardware resources (CPU, RAM, storage) into separate portions.
• Dedicated Allocation: Each portion of resources is allocated to a single VPS, meaning your VPS has its own amount of RAM and CPU and is not affected by other users, providing superior stability.
• Independent Operation: Each VPS functions like a true dedicated server, allowing you to install your own operating system (Linux, Windows) and have full administrative control (root / Administrator).
• Inherited Geographic Advantage: Since the underlying physical server is in Vietnam, your VPS automatically benefits from extremely fast access speeds and is optimized for Local SEO within the domestic market.

Key Benefits of a Vietnam VPS

Choosing a Vietnam VPS offers numerous competitive advantages for projects focused on the domestic market:

• Superior Access Speed: Minimizes network latency for users in Vietnam, enhancing user experience and customer retention.
• Full Administrative Control: Allows for the installation of custom software and deep configuration to meet any project's specific requirements.
• Dedicated Resources: Ensures stable performance that is not affected by other users on the same physical server.
• Local SEO Advantage: A Vietnamese IP address is a crucial signal that helps websites rank higher in search engines for the Vietnamese market.
• Stable Connectivity: Less affected by international submarine cable incidents, ensuring service continuity.
• Convenient Support: Services in Vietnam offer the advantage of support in Vietnamese, making it easy for customers to discuss needs, resolve issues, and receive advice without language barriers or time zone differences.

Applications and Use Cases

With its dedicated resources and high customizability, a Vietnam VPS is the ideal choice for:

• High-Traffic Websites/Applications: E-commerce stores, large forums, or web applications that demand significant resources.
• Game Servers: Provides a stable, low-latency environment for online games with players in Vietnam.
• Data Storage and File Sharing: Build private or internal cloud storage solutions for businesses.
• Development & Testing Environments (Dev/Test): Create an isolated environment to develop and test applications before deployment.

Choosing a high-quality Vietnam VPS is a strategic investment decision that goes beyond simply finding a low-priced plan. A truly reliable service must ensure long-term stable performance, which depends on several technical factors that not all providers disclose. Here are the crucial criteria you should use for your evaluation:

• Virtualization Platform:

  This technology determines the level of resource independence. KVM (Kernel-based Virtual Machine) is considered the gold standard as it provides completely separate and dedicated resources (CPU, RAM), superior to older platforms like OpenVZ or XEN.

• Physical Server (Node) Hardware Configuration:

  The performance of your VPS is directly dependent on the parent server. Evaluate the CPU (prioritize enterprise-grade server CPUs like Intel Xeon Gold / Platinum) and the storage type (it should be Enterprise SSD or NVMe in a RAID-10 configuration for speed and data safety).

• "Overselling" Policy:

  This is a critical but often overlooked factor. Ask the provider about the maximum number of VPS instances per physical server. If a node is shared among too many virtual machines, network speed and disk I/O will be severely degraded, even with KVM virtualization.

• Bandwidth & Network Connection:

  You must evaluate both types of bandwidth. Domestic bandwidth determines the connection speed for users within Vietnam, while international bandwidth affects global users. A reputable provider should offer a clear commitment to a minimum guaranteed bandwidth, not just a maximum "up to" figure.

• Scalability and IP Address Quality:

  A good service must allow for easy upgrades and the addition of IP addresses. For tasks like SEO or Email Marketing, being allocated clean IPv4 addresses (not on any blacklists) is extremely important.

• Technical Support:

  A 24/7 support commitment should be verified by the speed and quality of responses from a professional technical team, not just an automated ticketing system.

An Offshore VPS (often referred to as an "International VPS" or "Overseas VPS") is a virtual server created from a physical server located in a data center in a country different from that of the user or their company. This is often done to reach a local market in that country or to take advantage of different legal or cost policies.

For users in Vietnam, an Offshore VPS is any service with a physical server located outside of Vietnam. Common options are often named by location, such as VPS USA, VPS Singapore, or VPS Hong Kong. An offshore VPS is suitable when you need to reach an international audience, but it will have higher latency when accessed from Vietnam.

Technical Working Principle

When a user from Vietnam accesses an Offshore VPS, the data stream must travel a long distance, which leads to the following technical characteristics:

• International Routing: Data must travel through multiple international gateways and submarine fiber optic cable systems to reach the server abroad.
• High Latency: The long physical distance significantly increases network latency, making the VPS's response time slower compared to a domestic VPS.
• Reliance on International Infrastructure: Connection speed and stability are entirely dependent on international network infrastructure. Incidents like submarine cable breaks will cause severe performance degradation.

Key Benefits of an Offshore VPS

An Offshore VPS is a suitable solution that offers many benefits for internationally-oriented projects:

• Reach International Markets: Optimizes speed and experience for users near the data center's region (e.g., a Singapore VPS is optimal for Southeast Asian users).
• Flexibility in Legal and Policy Matters: Allows services to be hosted in countries with specific legal regulations on data, copyright, etc., that fit the project's needs.
• Geographic Location Diversity: Provides a wide choice of countries for server location, helping to optimize for each specific target market.

Key Drawbacks When Used in Vietnam

While useful for international markets, an Offshore VPS presents significant barriers when you need to serve users in Vietnam:

• Slow Speed: Access speed from Vietnam is considerably slower and less stable due to reliance on international submarine cable infrastructure.
• Support Barriers: You may face difficulties when urgent technical support is needed due to language barriers (usually English) and time zone differences.
• IP & Local SEO Disadvantages: A foreign IP address is not prioritized for searches in Vietnam, and the quality ("cleanliness") of the IP range needs to be carefully verified.
• Complex Payment & Legal Issues: Often requires international credit cards, carrying currency exchange risks, as well as potential legal issues regarding user data storage.

Applications and Use Cases

An Offshore VPS is an essential choice for the following scenarios:

• Global Applications/Services: Web applications or SaaS platforms with users in many different countries.
• International Game Servers: Serving players from a specific region or around the world.
• VPN/Proxy Services: Creating network access points in desired countries.
• Projects with Specific Jurisdictional Requirements: Storing data or hosting services in countries with a suitable legal framework.

The image below displays a speed test performed with tocdo.net on a live production server for VietHosting's entry-level KVM VPS - 01 package.

* Our VPS plans include a network speed of 1Gbps (Domestic) / 32Mbps (International).

* This indicates the maximum shared bandwidth for your VPS.

1. What is Bandwidth?

Bandwidth is the maximum data transfer capacity of a network connection over a specific period, typically measured in Mbps (Megabits per second) or Gbps (Gigabits per second).

To make it easier to understand, you can think of bandwidth like the width of a highway. The wider the road, the more cars can travel at the same time. Similarly, the larger the bandwidth, the more data (images, videos, text) can be transferred between your website and your users per second.

2. Understanding Megabits (Mbps) vs. Megabytes (MB/s)

This is the most common point of confusion. Network service providers (including VietHosting) typically advertise bandwidth speed in Megabits per second (Mbps), but the file download speed in your browser is shown in Megabytes per second (MB/s).

The conversion rule is simple: 1 Megabyte = 8 Megabits.

• To calculate the theoretical maximum download speed (in MB/s), you simply divide the advertised speed (in Mbps) by 8.
• Example: A hosting plan with 100 Mbps bandwidth will have a theoretical maximum download speed of 100 / 8 = 12.5 MB/s. The actual speed might be slightly lower due to transmission overhead, which is why you might see speeds around 10-12 MB/s.

3. Domestic Bandwidth

This is the data transfer rate for network connections within Vietnam's territory. This bandwidth is optimized for high speed and extremely low latency, making it ideal for websites and applications primarily serving users in Vietnam.

4. International Bandwidth

This is the data transfer rate for connections from Vietnam to other countries and vice versa. Due to long geographical distances, international bandwidth typically has higher latency and lower committed speeds compared to domestic bandwidth.

5. Shared Bandwidth Policy at VietHosting

To provide services at a reasonable cost, we operate on a shared bandwidth model. This means the advertised network speed is the maximum port speed your service is connected to. If your project requires guaranteed network speeds or needs dedicated bandwidth, please contact us for a consultation on a suitable solution.

VietHosting operates on a shared bandwidth model for its services. Therefore, the advertised network speeds (e.g., Domestic Bandwidth 1 Gbps, International Bandwidth 32 Mbps) represent the maximum allowed speed that VietHosting's system sets and limits for your service on our shared network infrastructure. This is not the same as dedicated bandwidth reserved solely for each customer.

Because this bandwidth resource is shared among multiple users and the maximum speed is limited by the system, VietHosting does not guarantee that you will consistently achieve this maximum allowed speed. Actual speeds will depend on the overall network traffic at the time of use and our bandwidth management policies.

If you require stable network speeds or guaranteed dedicated bandwidth for your service, please contact VietHosting directly. We will provide detailed consultation and pricing for suitable dedicated bandwidth solutions.
