Can I run another virtual machine inside my VPS?
Running a virtual machine inside a VPS requires nested virtualisation support and provider permission. A guest administrator cannot enable hardware extensions that the outer hypervisor does not expose. Compatibility and migration restrictions depend on the complete platform.
Instructions
1. Confirm the service permits nesting
Describe the intended nested hypervisor and workload. Ask whether CPU extensions, virtual devices and resource allocation are supported, and whether nesting affects migration, recovery or support eligibility.
2. Inspect the Linux guest capabilities
For a Linux KVM-based nested setup, inspect the guest view without loading modules or changing host policy.
lscpu
ls -l /dev/kvmCPU feature exposure and an accessible KVM device are relevant signals, but they do not independently prove the provider supports the full nested workload.
3. Validate a controlled nested deployment
Use the nested hypervisor’s official requirements and leave resources for the outer guest. Test boot, networking, storage and recovery in a nonproduction workload before relying on it. For Hyper-V or another guest hypervisor, follow that platform’s specific supported nesting requirements.
Check the result
- The provider explicitly supports the intended nested virtualisation use case.
- A controlled test validates the nested guest and its required network and storage behaviour.
Troubleshooting
- Virtualisation extensions are not exposed
- The outer platform must supply them; changing a guest configuration cannot create that capability.
- A nested guest starts but performs poorly
- Review scheduling, memory and storage overhead at both guest levels, as well as provider support limits.
