[Launched] Generally Available: Azure Site Recovery Support for Azure Trusted Launch VMs Running Linux OS

-


Azure Site Recovery (ASR) has officially launched general availability support for Azure Trusted Launch virtual machines (VMs) running Linux operating systems. This means that Azure customers can now use ASR to provide disaster recovery and replication capabilities for Linux VMs secured with Trusted Launch, a feature that enhances VM security through mechanisms like Secure Boot and measured boot.

Key details include:

  • Supported Linux distributions: ASR supports Trusted Launch VMs running major Linux distributions such as Ubuntu (18.04, 20.04, 22.04, 24.04), Red Hat Enterprise Linux (various 8.x and 9.x versions), SUSE (15 SP3 to SP6 with specific kernel versions), Alma Linux (8.10, 9.4, 9.5), and Debian 12[1].

  • Support status: Previously, ASR support for Trusted Launch was generally available for Windows VMs, while Linux support was only in private preview. As of now, Linux Trusted Launch VM support has transitioned out of preview to general availability, providing full disaster recovery support through ASR[2][3].

  • Limitations and considerations: ASR supports only stock kernels included with the supported Linux distributions and does not support custom kernels on Trusted Launch VMs. Also, Secure Boot is foundational for Trusted Launch, ensuring that only signed and trusted OS components boot, which ASR fully supports for replication scenarios[1][4][5].

This general availability release allows enterprises to leverage Azure's enhanced VM security features with Trusted Launch on Linux while benefiting from reliable disaster recovery and business continuity through Azure Site Recovery.

In summary, Azure Site Recovery now fully supports disaster recovery for Azure Trusted Launch virtual machines running Linux OS, enabling secure, resilient Linux workloads in Azure.
