Virtualization host

Proxmox VE 8 and 9 preinstalled at no extra charge

The AMD EPYC 7543P delivers 32 cores and 64 threads, with 128GB or 256GB of DDR4-3200 ECC memory.

Preinstallation does not replace VM planning. The account holder manages disk layout, IP allocation, and backups.

Host specifications

AMD EPYC 7543P

Compute

32 cores / 64 threads

AMD-V (SVM) and NPT provide hardware virtualization for KVM VMs.

Storage

Both drives are direct-attached and independent. Configure storage pools and mirroring on the host.

Management IP

First IPv4 address

The first address is reserved for host management; allocate additional addresses according to your needs.

Hardware virtualization

AMD-V and NPT for a KVM host

The EPYC 7543P is a single-socket processor, and the processor and memory in the server are dedicated to one account. The host configuration determines how resources are allocated between VMs, overcommit ratios, and scheduling.

SVM: CPU virtualization

AMD-V SVM enables hardware-assisted virtualization. After installing Proxmox VE, check that the host recognizes the virtualization features before creating KVM VMs and assigning vCPUs.

64 threads describes the server's hardware; it is not a capacity commitment for 64 VMs running at full load. Capacity planning should account for concurrency, CPU utilization, and disk load on each VM.

Allocate vCPUs for actual workloads

NPT: nested page tables

NPT provides nested page tables for virtual memory address translation. Actual performance also depends on guest memory, access patterns, available host memory, and storage latency.

When setting up production VMs, plan CPU and memory budgets together. Adding vCPUs alone does not address memory pressure.

Plan CPU and memory together

Nested virtualization: run KVM inside a VM

Enable nested virtualization on the host and expose the required CPU features to a first-level VM to run KVM inside it. This is useful for validating virtualization workflows, isolated lab environments, and test images.

Nested virtualization is not enabled automatically when a VM is created. Check the host kernel settings, the first-level VM's CPU configuration, and the guest's reported features. Include nested virtualization overhead in capacity planning.

Check virtualization features at each layer
Memory planning

Choose 128GB or 256GB based on peak usage

Both tiers use DDR4-3200 ECC RDIMMs. ECC can detect and correct memory errors, making it suitable for always-on hosts. It does not replace VM backups or guarantee that application data is always correct.

128GB: check the total workload budget

Suitable for deployments with a defined VM count and memory limit. Reserve capacity for the host, storage cache, and background tasks before allocating the remainder to guests. Do not assign the full advertised capacity to VMs.

With ZFS, include cache requirements in the host budget. Account for peak memory use from databases, build jobs, and bulk imports in each VM's allocation.

128GB DDR4-3200 ECC

256GB: accommodate defined memory needs

Suitable when total VM memory requirements exceed the 128GB tier's budget or when capacity needs to be kept available for additional guests. The processor, standard drives, and default network specifications remain the same across memory tiers.

Select the memory tier before ordering. The existing server cannot be upgraded after deployment; changing tiers requires ordering another server and arranging workload and data migration.

256GB DDR4-3200 ECC

Estimate capacity: advertised memory is not the same as guest allocation

Guest budget = total server memory − host and storage budget − operating headroom

The example below illustrates a budgeting method; it does not represent default system usage or guaranteed available capacity. For example, reserve 16GB for the host and storage and another 16GB for operating headroom. At 8GB per guest:

Server memory tier Guest memory budget Example allocations at 8GB per guest
128GB 128 − 16 − 16 = 96GB 96 ÷ 8 = 12 VMs
256GB 256 − 16 − 16 = 224GB 224 ÷ 8 = 28 VMs

This example accounts for memory only; it does not mean these VMs can all run at full compute or storage load simultaneously. Before going live, test representative workloads, monitor memory reclamation, disk wait, and CPU usage, then adjust allocations. Swap space cannot make up for a sustained shortage of physical memory.

Storage layout

Two direct-attached NVMe drives, with storage pools configured on the host

The standard setup includes 2×1TB NVMe drives, each direct-attached, with no hardware RAID. The drives do not come preconfigured as a RAID-1 array. Decide on capacity, redundancy, and recovery before creating a storage pool.

ZFS mirror: plan for redundancy

Proxmox VE can use the two standard drives to create a ZFS mirror. Usable capacity is based on one member drive, minus formatting, metadata, and required headroom. Do not estimate capacity by adding the two drive sizes together.

Creating or rebuilding a storage pool may overwrite disk contents. Verify device identities and complete a backup before performing storage operations.

A mirror is not a backup

Separate storage: allocate drives independently

The two drives can also be planned as separate devices, with storage allocated to different VMs or workloads. This setup does not provide mirrored redundancy automatically; a drive failure may affect guest disks and data on that drive.

When estimating capacity, allow for snapshots, image templates, and data growth—not just the initial size of VM disks.

Direct-attached, no hardware RAID

Additional drives: store guest disks separately

Add 0 to 2 additional 2TB NVMe SSDs for $70/month each. Each drive is direct-attached. New drives can be placed in a separate data pool for guest disks or other storage needs.

Adding drives does not automatically expand an existing ZFS mirror. Plan pool structure, data migration, and backups for the actual layout.

Add up to 2×2TB NVMe

Snapshots stored on the same server remain vulnerable to server failure and accidental changes. A recovery plan should include off-site backups and recovery testing; backup copies should not be kept only in the original storage pool.

Multiple IPs

Use the first address for host management and allocate additional addresses to workloads

Each server includes 1 dedicated IPv4 address, with up to 255 additional addresses available, for a maximum of 256. Additional IPv4 addresses cost $2/month each and are billed individually. Assigned addresses are available in the portal after delivery.

Included1 IPv4 address

The first address is for host management and the initial SSH connection.

Additional0–255 addresses

Choose a quantity based on guest count and workload requirements.

Maximum total256 IPv4 addresses

The number of addresses and the number of VMs the server can run are separate measures.

  1. 01

    Keep the management path available

    Check the first IPv4 address and host credentials in the portal, and confirm that the management connection works. Record management and workload addresses separately to avoid configuring the same public IP on both the host and a guest.

  2. 02

    Configure a network bridge

    Use a Proxmox VE network bridge to assign additional addresses to VMs. Use the delivered gateway, netmask, and routing details; do not infer network settings from neighboring addresses or enter unverified parameters.

  3. 03

    Test each guest

    Assign a purchased address to the guest, check its network settings, firewall, and return route, then verify inbound and outbound connectivity. Keep a record mapping each address to its guest after every change to help troubleshoot conflicts and plan workload migrations.

Operating systems

14 free operating systems for host and guest workloads

The configurator offers the free operating systems below. Proxmox VE 8 and 9 can be used as virtualization hosts; the other distributions are options for guest systems. Choosing a preinstalled OS for the server and installing an OS inside a VM are separate steps. A preinstalled host does not create guest VMs automatically.
