Example for KVM :

Core(s) to utilize on server (÷) total core(s) allocated to VPS x 100 = CPU% value.

Example 1 : If you've KVM VPS with 4 cores and you want it to utilize only 2 cores on the host server , then you can set the CPU% value as 50.

2 ÷ 4 x 100 = 50 (CPU%)

Example 2 : If you've a KVM VPS with 4 cores and you want it to utilize only 1 core on the host server , you can set the CPU% as 25.

1 ÷ 4 x 100 = 25 (CPU%)

Note : Each CPU core represents 100% of one physical core. This behavior may be different as per the base OS as well.

Name	Description	Supported Virtualization
Disk Space	In VPS systems, there are different disk storage options: 1. Thin: Efficient storage allocation, dynamically allocating disk space as needed. 2. LVM (Logical Volume Manager): Advanced disk management with features          like resizing and snapshots. 3. Raw: Direct disk access without additional layers or filesystems. 4. File: VPS disk stored as a regular file, offering simplicity and portability. The choice depends on factors like storage efficiency, management capabilities, and specific use cases for the VPS.	All

Advanced Options

Network Settings

Suspend the VPS if it is uses more than specified bandwidth	All
Disable ebtables	Lorem ipsum	All
Disable Network configuration	If checked, Virtualizor will not configure/re-write network when a VPS is rebooted. However, during creation of the VPS, the network file will be written.	All

Vertical Scaling settings

Name	Description	Supported Virtualization
Vertical Scaling	Vertical Scaling is a valuable feature that allows Virtual Private Servers (VPS) to automatically adjust their resources based on defined thresholds. This ensures optimal performance during peak loads by dynamically scaling RAM and CPU cores. Administrators or users can easily configure maximum limits, thresholds, and resource allocation changes on a per-VPS basis. Vertical Scaling guarantees that your VPS maintains efficiency and responsiveness, even during high-demand periods. (This feature is available for KVM only )	All

Control Panel

Virtualizor allows endusers and admins to install some Control Panels directly on the VPS. However, shutting down the VPS will be required in case of Xen and KVM VPS. list of Control panel is 
1. Webuzo
2. Plesk
3. Cpanel
4. Webmin
5.Interwarx
6.ISPConfig
7. Centos Web Panel
8. VestaCP

CPU

Name	Description	Supported Virtualization
CPU Affinity	Pin the particular CPU Cores to this VPS. You can choose multiple CPU Cores.	All
CPU modes	Predefined CPU modes in virtualization enable administrators to specify the desired CPU feature sets for virtual machines. These modes define the level of compatibility and performance between the virtual CPUs and the underlying physical CPUs. By selecting an appropriate CPU mode, administrators can optimize the balance between compatibility and performance for their virtualized workloads.	KVM, Proxmox KVM
CPU Topology	CPU topology in virtualization refers to aligning virtual CPUs (vCPUs) with the physical CPU architecture to optimize performance and resource utilization in virtual machines (VMs). It ensures efficient communication, cache locality, and utilization of computing resources.	KVM, Proxmox KVM, XCP
CPU Threshold	A CPU Threshold is a preconfigured level of CPU utilization that helps monitor the CPU usage of a virtual machine (VM). It enables administrators to set a limit for CPU usage on a server. With Virtualizor, you can establish a time limit for exceeding CPU usage, and the system will watch for and notify you about any VPS (Virtual Private Server) that surpasses the designated threshold. In such cases, Virtualizor provides the option to suspend the VPS temporarily. The calculation of CPU usage may vary depending on factors like the number of CPU cores and the assigned CPU %, which can be adjusted based on your specific requirements. This feature allows for effective management and control of CPU resources within the virtualization environment.	ALL

Miscellaneous Settings
