Complete Guide to Installing Proxmox VE 9.2 for Arm64

Proxmox Virtual Environment (VE) has announced its first edition for Arm64 architecture, marking a significant step beyond the x86-64 architecture. This new version offers the same robustness and functionality as the x86-64 version, making it a reliable solution for virtualization on Arm64 hardware.

This edition is useful for system administrators and IT professionals who want to leverage Proxmox's virtualization capabilities on Arm64-based servers. It is particularly advantageous for those working in data center environments, cloud computing, computational acceleration, artificial intelligence training, and inference.

Proxmox VE 9.2 for Arm64 is built on Debian 13.5 "Trixie" and uses Linux kernel 7.0 as the default stable version. It includes key components such as QEMU 11.0, LXC 7.0, and ZFS 2.4, ensuring compatibility and optimal performance.

The new version supports the entire virtualization and storage infrastructure of the platform, including KVM, LXC, software-defined networking, high-availability clustering, backup, ZFS, and Ceph. Users can manage the environment through the usual web-based interface.

The development and validation of the Arm64 version were carried out in technical collaboration with NVIDIA and Supermicro, using server systems based on the NVIDIA Grace Hopper Superchip. Official support is initially directed towards systems using NVIDIA Grace Hopper and NVIDIA Vera processors.

Proxmox VE for Arm64 is available immediately, both as a dedicated ISO image for bare-metal and through the package repositories along with the current x86-64 versions.

Verification and Troubleshooting

After installing Proxmox VE 9.2 for Arm64, it is essential to verify the correct functioning of the system and resolve any issues.

How to Test if It Works

• Boot Verification: Ensure the system boots correctly using UEFI and describes the hardware via ACPI.
• Virtual Machine Check: Create and start an Arm64 virtual machine using AAVMF to verify that the virtualization environment works correctly.
• Live Migration Test: If you have multiple Arm64 nodes, perform a live migration to ensure the process is smooth and error-free.
• Backup and Restore Verification: Perform a backup of a virtual machine and restore it to confirm that the backup process works correctly.

What to Do if It Fails

• Boot Issues: If the system does not boot, verify that the hardware supports UEFI and ACPI. Also, check that the system firmware is up to date.
• Virtualization Errors: If virtual machines do not start, ensure you are using AAVMF for UEFI boot. Verify that the host system has the same architecture as the virtual machine.
• Failed Live Migration: If live migration does not work, ensure all nodes involved have the same architecture. Also, check the network connectivity between the nodes.
• Backup and Restore Issues: If backup or restore fails, verify that the data is accessible and that the storage system is compatible.

For further details and support, consult the Proxmox forum or the official announcement.

By the end of this guide, you will have understood the main features and differences between the Arm64 version of Proxmox VE 9.2 and the x86-64 version, as well as the practical implications for implementation.

• Educational Summary: The new Arm64 edition of Proxmox VE 9.2 offers the same robustness and functionality as the x86-64 version, but with some architecture-specific limitations, such as the lack of support for x86-specific technologies and the need to use AAVMF for virtual machine boot.
• Call to Action: To explore the potential of the Arm64 version, download the dedicated ISO image or update through the package repositories. Start with installation on officially supported hardware, such as systems based on NVIDIA Grace Hopper and Vera, to ensure compatibility and stability.
• Future Considerations: Proxmox is evaluating the introduction of other products in its ecosystem to Arm64, such as Proxmox Backup Server. Monitor official updates to stay informed about new features and extended hardware support.
