Which virtualization solution does Tilaa use?

Virtualization serves as the foundation for a comprehensive set of hosting options known as Virtual Private Server (VPS) Hosting. Unlike shared hosting, VPS hosting provides complete isolation from other users on the hosting server. It gives you complete control over your account (root access), as well as the ability to perform remote reboots and system restoration. 

Tilaa employs KVM as its virtualization solution because it improves the performance, stability, and flexibility of handling simulated devices by utilizing the disk subsystem more effectively.

What is KVM virtualization? 

KVM (Kernel-based Virtual Machine) is an open-source Linux kernel module that allows the creation of emulated/virtualized hardware that can be used to boot virtual machines. It is supported by Red Hat Enterprise Linux.  

Advanced features of KVM virtualization  

KVM has a wide range of capabilities, including the ability to manage 8 different genres, which makes it an obvious choice as our preferred hypervisor. 

1. Security:  

For improved VM security and isolation, KVM combines security-enhanced Linux (SELinux) with secure virtualization (sVirt). 

2. Live Migration: 

KVM has excellent checkpointing and live migration capabilities. 

3. Hardware Support:  

KVM supports a wide range of Linux-compatible hardware, and because hardware companies play an important role in kernel development, it adapts quickly in the Linux kernel. 

4. Storage:  

Because it is a Linux component, KVM also supports any storage that Linux supports. KVM uses multipath I/O to eliminate redundancy and thus increase storage capacity. 

5. Management:  

Each process that runs from the guest side to the host node can be linked using the KVM framework. This is useful for identifying which guests are causing issues and stopping the process to avoid any downtime on the guest's end. 

KVM inherits Linux's memory management features, making it even more up to date in terms of upgrades. Important recent KVM capabilities are non-uniform memory access and kernel same-page merging. 

 6. Compatibility:

With KVM, true virtualization is possible. It allows you to run any operating system and tinker with kernel settings at a basic level. KVM will only run on hardware that supports hardware-assisted virtualization. 

Conclusions 

Because data is hidden from other users, KVM provides excellent isolation in terms of privacy. It also simulates diverse hardware, allowing you to run any kernel you choose inside its confines. This means that KVM isn't limited to the Linux kernel running on the root node. Other x86 operating systems can also be run by KVM (e.g. Windows and BSD). It also functions as a hypervisor, allocating and managing shared resources such as CPU time and network I/O.
