Pick your hypervisor.
Root your own box.
SiteServing runs XEN, KVM, and OpenVZ side by side on the same AMD EPYC / NVMe fleet, so you can deploy a VM on whichever virtualization model your stack actually needs, with full root access from the first boot.
One fleet, three virtualization models
Every hypervisor sits on identical hardware. The difference is how much of the kernel your VM gets to itself, so pick the model that matches your workload, not the other way around.
XEN
A thin hypervisor runs directly on the hardware. A privileged control domain (Dom0) manages a set of guest domains (DomU), each running a hypervisor-aware kernel through paravirtualized drivers, delivering near-native performance with hardware-level separation between guests.
- IsolationHardware-level, separate kernel
- Custom kernelYes
- Typical overheadLow
- Live migrationYes
- Best forCustom kernels, GPU passthrough, strict isolation
KVM
KVM turns the Linux kernel itself into a hypervisor using hardware virtualization extensions (Intel VT-x / AMD-V). Each guest runs a complete, independent kernel and behaves like it's on dedicated hardware, including unmodified Windows or BSD images.
- IsolationHardware-level, separate kernel
- Custom kernelYes, any OS
- Typical overheadLow–moderate
- Live migrationYes
- Best forUnmodified OS images, Windows guests, general purpose
OpenVZ
Containers share a single host kernel and isolate everything else (filesystem, processes, network) through kernel namespaces. No per-guest hypervisor overhead means more density per node, at the cost of running the host's kernel version.
- IsolationProcess / namespace-level
- Custom kernelNo, shares host kernel
- Typical overheadMinimal
- Live migrationLimited
- Best forHigh-density budget VPS, predictable Linux workloads

Every plan includes a dedicated IP, root SSH and API access, network-level DDoS filtering, and free migration from your current host within 30 days of signup.
Built to stay up
Every node is monitored around the clock across redundant upstream networks, with DDoS filtering applied before traffic ever reaches your VM.
