MarvinMC A KVM server is a virtual machine with its own virtual disk and operating system. Use it for applications, game servers, websites or development environments. You manage and update the guest operating system yourself.
Step by step
- Open your server. Overview shows state, runtime, address and resources. Use the power controls to start, stop or restart it.
- Open Operating system. On a regular QEMU/KVM container you can automatically install Debian or Ubuntu or upload your own bootable x86-64 ISO.
- Open Console. SSH and the serial emergency console are shown by default. Select the VNC tab for graphical access, including during installation and when guest networking is misconfigured.
- Use SSH, or configure RDP yourself for a custom Windows installation. Set strong passwords, install updates and configure a guest firewall.
- Configure Ports to forward traffic to guest services. A dedicated IP simplifies direct access; an A-record subdomain requires a dedicated IP.
- Create a snapshot before major changes. Files, FTP, access permissions, events and crash restart are available in their respective server sections where the backend supports them.
Check the result
Verify console access and test a service from outside. RAM statistics show actual container consumption, including the VM process and cache, so they can differ from htop inside the guest.
Important
A VPS still needs backups outside the VM. Snapshots are stored on the same host. You are responsible for OS licenses and application configuration. Proxmox servers have separate image and management features; these ISO instructions describe regular QEMU/KVM containers.
