On April 9, Proxmox – the European open-source IT infrastructure software provider – released version 8.4 of its server virtualization management platform, Proxmox Virtual Environment (VE).

CanaryBit’s Confidential Computing Remote Attestation support for AMD SEV-SNP is among the range of improvements and new features in this version. It includes:

Initial support for AMD SEV-SNP (Secure Nested Paging).

– On supported setups, SEV-SNP can further increase isolation between host and guest.
– As EFI disks are not supported when using SEV-SNP, print a warning that EFI disks are ignored

Remote attestation is a core component of Confidential Computing. It helps verify the integrity of a processing environment for both cloud and on-prem setups. It helps build trust in digital infrastructure and ensure compliance with global data privacy regulations.

With more than 1.5 million hosts and more than 200,000 active community members, Proxmox VE is the open-source virtualisation solution. Thousands of companies choose it as the alternative to Broadcom/VMware ESXi, Microsoft Hyper-V or Citrix XenServer.

We are impressed by the work Proxmox has done over the last 20 years in the open infrastructure virtualization space. We will continue to contributing to enable Confidential Computing support for other hardware platforms, such as Intel TDX and NVIDIA H100+.
