Connecting the SystemRescue image to a virtual server
SystemRescue is a Linux operating system image available on CD-ROM or USB media for system administration or debugging. The image does not require installation and is available for use as soon as you start it from the disk or USB. By default, it comes with a large amount of software, such as disk management tools, file system tools, network administration programs, and simple text editors. The system comes with the latest kernels to support the latest hardware.
Connecting the image to a virtual machine
To connect the recovery image to a virtual machine, you first need to download it. You can do this by going to the official recovery image website - https://www.system-rescue.org or use the image we have already tested in action SystemRescueCd 5.1.2.
Go to the website and open the "Download" tab. Download the image according to the system architecture, for example, amd64 for 64-bit systems.
After that, go to the VMmanager control panel.
BILLmanager 5: "Products/Services" tab => "Virtual Servers" tab => select the server => click "Go".
BILLmanager 6: "All Services" tab => "Virtual Servers" item => right button with three vertical dots => "Go to panel" item.
After accessing the control panel, go to the "Management" tab => "Virtual Servers" item. Select the desired server and click "Stop". Then, click on the "ISO Images" button and then on the "Upload" button.
* By default, many virtual servers already have the SystemRescue image connected.
Go back to the "Virtual Machines" tab, click on the "Disks" button, and connect the newly uploaded image to our virtual machine.
* If you encounter a notification during the connection process, wait a few minutes. Sometimes, the waiting time can be longer than a few minutes, but there is no need to worry.
"The selected ISO image is not available on the cluster node where the virtual machine is located. If the image was recently uploaded, wait for the image synchronization between the cluster nodes to complete. The synchronization speed depends on the image size and communication channel parameters."
After connecting the image, you can go to the "Virtual Servers" tab and start the virtual machine. Note that if you want to start SystemRescue in a specific mode (there are 6 modes available), do not hesitate to switch to the "VNC" tab, which you can do by clicking on the corresponding button. If there is no activity, the default option (1) will be selected.
This is what the SystemRescue startup screen looks like.
Conclusion
Now you know how to connect a system recovery image in case of any failures and attempt to debug the error. This method allows you to connect not only the image we mentioned, but also others.
