Kernel support for disaster recovery (Site recovery extension does not support the Linux operating system kernel version running on the source machine.)

Samuel Turcotte 30 Reputation points

Documentation says that kernels are supported within 15 days after release. "To support latest Linux kernels within 15 days of release, Azure Site Recovery rolls out hot fix patch on top of latest mobility agent version."

My Ubuntu 22.04 kernel is 6.2.0-1012-azure. Max supported version is 5.15.0-1039-azure in documentation (

I've been waiting over two month, but still no support for 6.x kernels

Thank you

    Hello @Samuel Turcotte Appreciate your patience in this matter!

    We were planning for adding support of Ubuntu 6.2 kernels from agent version 9.57, however during our internal testing, we are seeing that ASR driver is not able to detect an important signal as it is not getting the notification for the same, which may lead to potential issues. So, we are working on resolving this issue and hence, this kernel support will come from 9.58 tentatively.

    Thanks once again for your understanding!
