CPU Threshold: A CPU Threshold is a preconfigured level of CPU utilization that monitors the CPU usage of a virtual machine (VM). It allows administrators to set a limit for CPU usage on the server. With Virtualizor, you can incorporate a time limit for exceeding CPU usage, and the system will monitor and notify you about any VPS that surpasses the designated threshold.  In such cases, Virtualizor offers the option to suspend the VPS temporarily. The calculation of CPU usage may vary based on parameters like the number of CPU cores and the assigned CPU %, which can be adjusted based on your particular requirements. This feature gives effective management and control of CPU resources within the virtualization environment.

Supported VPS: All

Media

Media groups allow the admin to manage the ISOs/OS templates that are used for developing the Virtual Private Servers. You can group various ISOs in a single media group and assign that media group to a particular enduser, making sure that enduser has access to only those ISOs for creating Virtual Private Servers.  Use the Mediagroups API to register all the mediagroups present on the server.

 

Networking

Network settings for a virtual machine (VM) include configuring essential parameters such as DNS nameservers, internal IP address, bandwidth, and the virtual network interface type. These settings give proper communication between the VM and other devices, controlling network access and data transfer, and defining the virtual network interface’s MAC address.

 

 

Description

Bandwidth: Bandwidth in the context of virtual machines VMs, refers to the data transfer capacity of the network connection, we can control both downloading and uploading speed. It defines how much data can be sent from the VM to other devices or networks within a given time frame. Higher bandwidth helps to speed up the data transmission, enabling VMs to send data more quickly and smoothly. It automatically gives effortless and responsive network communication for virtualized workloads.

Bandwidth Suspend: If bandwidth suspend enables then it’ll suspend the VM if use of bandwidth is completed.

Capped Download/Upload Speed: Capped download/Upload speed limits the maximum data transfer rate in a virtual machine (VM) to manage the network traffic if bandwidth is overused for a VM.

Internal IP: Giving a public IP to the cloud control panel helps internal communication within the private network.  

MAC Address: Unique identifier for a network interface, aiding in device identification and communication on a network.

Virtual Network Interface Type:  Virtual Network Interface Type refers to the type or model of the virtual network interface (NIC) allocated to the virtual machine (VM).  The virtual network interface type can vary based on the virtualization platform being used, and its influencing parameters are network performance, compatibility, and supported features within the VM.

DNS Nameserver: It helps the VM to resolve and access resources on the internet or within the local network by converting the human-readable domain names (like www.ukhostagor.com) into machine-readable IP addresses (like 101.188.67.134)

Disk

 

A disk driver is like a translator that allows the operation of a virtual machine (VM) to talk to and manage the virtual disks used for storing data in the VM. It bridges the gap between the VM and the storage system, ensuring smooth disk operations. Virtio and SCSI are similar types of disk drivers that make disk access efficient and optimized for VMs.

Description
