What virtualisation WebGee uses
WebGee cloud servers run on KVM, giving you your own kernel, your own firewall and full isolation from other tenants.
WebGee VPS and cloud servers run on KVM — a full hardware virtualisation hypervisor.
What that means for you
Your own kernel. You can load modules, apply kernel parameters and boot a custom kernel. Container-based virtualisation such as OpenVZ shares the host kernel, so none of that is possible there.
Your own firewall. iptables and nftables work normally, including
features that containers cannot support.
Real isolation. Memory and disk are allocated to your server, not shared opportunistically with neighbours. What another customer does on the same host does not consume your resources.
Anything runs. Docker, custom filesystems, swap, VPN software, alternative kernels — all work, because you have a real machine rather than a partition of someone else's.
Practical consequences
- Kernel updates are yours to apply, and you must reboot for them to take effect — see the Copy Fail kernel advisory for a worked example.
- Resources are dedicated, so a busy neighbour does not slow you down. It also means you cannot exceed your allocation opportunistically.
- A rebuild replaces the whole disk, not a container template — see Rebuild your server.

VNC gives you the server's screen directly, so it works when SSH does not. When to reach for it, and why to turn it off afterwards.
Meridian theme missing after a cPanel upgrade
cPanel 138 ships Meridian as a separate plugin that depends on ea-podman. If docker-ce is installed the plugin cannot install, and only Jupiter appears.
