What Is VDI And Why Is It Important?
Virtualizor is a powerful web-based interface for managing virtual machines (VS) on the internet. It enables IT administrators to manage servers, desktops, workstations, and virtual environments. The virtualizor software is a component of a complete virtualization solution that also includes Xen, a free, open-source software solution. Virtualizor also provides administrators with the ability to manage multiple virtualization domains from a single interface.
With virtualizor, administrators have access to real-time statistics for each VLAN of the virtual machine. Each virtualized OS instance has its own private local area network (LAN), which is subdivided into several smaller ones. Administrators can view overall resource usage details for each virtualized platform and each domain, in addition to details about individual processes and traffic on each LSI.
A virt-manager is a component of a virtual machine management tool or a virtualizor package. virt-manager contains a large amount of functionality for all types of virtualization. For example, it controls the virtual machine’s Ethernet driver, virtualization software, kernel, networking hardware, security features, virtual memory configuration, guest XML configuration settings, user information, system policies, hardware and software drivers, process monitoring, and system health. These processes are managed via a GUI, which can be customized by the administrator using command lines, shell scripts, or graphical interface programs.
One important function of the virt-manager is to provide support for the Linux guests using the Linux pass-through driver (LPT) or the kernel-virtualization feature. If the guest is running a kernel with the GLib software and the GLib utility, the virt-manager will load the appropriate modules automatically, such as the glib OpenSSL library. This saves the time required for establishing networking connections through libc and the OpenBSD operating system.
Virtually every modern operating system supports virtual memory pages. Virtualization is achieved through the hypervisor, which executes virtual machine applications within a single kernel. The hypervisor can abstract the kernel, execute virtual applications, control I/O, provide device input/output devices, manage memory resources, control networking, provide virtual storage, etc. The hypervisor is basically a kernel that runs inside a virtual machine. The hypervisor lets the administrator create virtual machines, attach virtual machines to an existing virtual machine, or provide a virtualized platform on which to run real programs.
In order to fully virtualize a physical computer, the virtual machine should implement the VCPP or virtual CPU Pinning mechanism. VCPP allows a hypervisor to have multiple independent process groups that can run independently of each other. Each process group can be independently controlled via the vCPU or through a hypervisor device such as the Virtio hypervisor. This ensures that the CPU performance, memory, I/O, processes, etc.
So now we have established what is VMT, the hypervisor and VPCP, how can we make use of it in our VDI solution? Well, for starters, VDI can become a very efficient way to utilize multiple CPU cores and large amount of resources for a small price compared to the cost of a complete server virtualization solution. A VDI can literally run multiple virtual servers on one CPU core while saving quite a bit of money.
Furthermore, virtual machines can scale up and down as needed without the need for increased memory usage. With VMT, the guest OS doesn’t need to run in a fraction of the system’s memory since the hypervisor has controls over the amount of memory that is used. For any production grade environment that needs a large amount of memory and a robust virtual machine, VDI will work exceptionally well. However if you’re looking to save money and improve virtual machine performance then VPS or simply guest virtual machine is a much better option.
