What is the difference between hyper-V, VMWare, and virtuozzo?

 

Hyper-V is Microsoft's virtualization product. It is Microsoft's first hypervisor-based technology similar to VMware and Citrix open-source xen.

VMware (Chinese name Wei Rui ", New York Stock Exchange" code: vmw) Virtual Machine software, is the world's leading provider of desktop-to-Data Center virtualization solutions

 

Virtuozzo introduction unzip ozzo is the name of swsoft's operating system virtualization software. This operating system virtualization software is a server virtualization and automation technology that uses the operating system virtualization technology.

 

 

Hyper-V and VMWare provide hardware-level virtual services, while virtuozzo provides virtual services on OS-level software.
Taking the server as an example, if one of the same server's javasozzo hosts is attacked, it will directly affect the failure of all other javasozzo hosts on this server. In the same case, hyper-V and VMWare only affect the attacked VM host, while other VM hosts on the same server are not affected.

Technology: virtuozzo is a Virtualization Technology Based on the software layer, specifically the virtualization of the operating system. hyper-V and VMWare are Virtualization Technologies Based on the hardware layer, hyper-V and VMWare are widely used in banking and aviation fields and are virtual server products with extremely stable performance.

Quantity: virtuozzo can Virtualize one operating system to hundreds of independent operating systems on one server, hyper-V and VMWare can only virtualize the corresponding host based on hardware conditions such as memory, hard disk size, and CPU resources.

Resource: The Hardware Memory is allocated in advance before hyper-V and VMWare run. If 16 GB of memory on the server cannot be allocated to 17 GB of memory, the virtuozzo server has 16 GB of memory, which can Virtualize GB or more memory and allocate it to hundreds of independent operating systems.

Essence: hyper-V and VMWare run the same thing as a real physical server, because they have obtained independent resources, while zooozzo is not independent. From the space occupied by the operating system, we can see that hyper-V and VMWare require the same size as the space required for installing the operating system on an independent server, as the operating system of virtuozzo only needs about MB, hyper-V and VMWare hosts need larger hard disk capacity and memory capacity.
