6.9 VPS KVM. Boot from ISO image, VNC
VPS on virtualization KVM is implemented on the basis of precise division of resources of real physical servers. You, as a Client, will not see any functional differences between KVM virtual servers and dedicated physical servers, and as a result you will receive high speed operation of your resources on a rented virtual server.
One of the advantages of VPS KVM is the ability to boot from the ISO images you need and install and configure any OS in the VNC terminal as if you were in front of a real server monitor.
In the server control panel in the Virtual machines section, you can, by selecting your server, stop/start it, reboot and reinstall it yourself. It is important to understand that when you reinstall the server, all data on it will be deleted without the ability to restore it.
The server properties indicate the internal id of the server, its name, domain name, the main IP of the server, the OS that was chosen when creating the server, the amount of memory allocated to the server, disk space and the number of cores, the percentage of disk space used by the server, the number of files (inode) and server state.
Using the context menu buttons Disks, Interfaces and IP addresses, you can manage the specified server elements. Making any changes is possible only if the server is stopped.
On the left in the menu you can open the sections Virtual machines, disks, ISO images, SSH keys and sections Statistics and User Settings.
To download your ISO image, you need to select the ISO images section - a list of already downloaded images will be displayed and in the window at the top left there is a Download button - click it to download the image you need and in the window that opens, specify the path to ISO file on your PC, or a URL to download the file from the network and specify the desired name of the downloaded file, under which it will appear in the list of ISO images after downloading.
You can only download images in ISO format; other virtual disk formats are not supported. If the download is successful, your ISO image will appear in the list of images in the ISO images section with the name you specified. One user can upload no more than 2 ISO images and their size cannot exceed 10 GB, the lifetime of the downloaded file is 48 hours, after its expiration the image will be deleted automatically.
After successfully uploading the image you need to the server, you need to mount it into a virtual CD-rom. To do this, be sure to stop your server, then select it and click Disks at the top right - your server’s disk window will open:
In the indicated window, click the ISO button to create a virtual CD-ROM - in its properties, specify the previously downloaded ISO file, set Boot order - To the beginning so that your server boots from this device first and click OK.
If you will be installing a Windows OS, we recommend that in the properties of the virtual disk in the same section, set the bus type to IDE instead of Virtio so that the virtual hard disk is visible to the OS installer.
After connecting the virtual CD-ROM with the mounted ISO image, in the Virtual machines section, select your server, turn it on with the Start button and click the VNC button at the top right - a virtual terminal window will open
An example of a VNC window with Windows installed is shown above. The specified window is a virtual terminal to access your server, as if you were directly in front of your server monitor. A virtual keyboard and mouse are also available. Using the button at the top right Send CTRLALTDEL you can also send a signal similar to pressing these 3 keys on your keyboard. For Linux operating systems, the window will have a regular black background and a command line. To log in, enter your username and password.
