Azure RHEL Linux VM updates , Gen2 supported?

Question

I am trying to add a RHEL8.2Gen2 VM to automated patching but its failing . I get the hybrid runbook worker is not running error when I run the trouble shooter.

I also get the following error when I go to the "Check For Updates" option on the VM page .

Update operation on 'Microsoft.Compute/virtualMachines', machine: 'hexdev-linux02-RHEL8.2'. Error details: {"error":{"code":"BadRequest","message":"The selected VM image is not supported for VM Guest patch operations. Learn more at: https://aka.ms/VMGuestPatchingCompatibility"}}

Looking at the webpage the error advises me to look at it says RHEL8.2 is supported, but it does not mention anything about Gen1 or Gen2 VMs.

Everything works when I use a Gen1 type VM image for the same RHEL8.2 distro.

Can anyone confirm if Check for Updates and automated patching for RHEL8.2 image should work if you use a Gen2 VM?

Answer 1

Please check this RHEL 8 image types Gen 2 type VM image will not work

• Generation 2 doesn't support the operating system you want to run on the virtual machine.
• Generation 2 doesn't support the boot method you want to use and Gen 2 are not available in every region it's depends upon the availability of the VM size. see Hyper-V feature compatibility by generation and guest.

Features included in generation 2

• Increased memory, Intel Software Guard Extensions (Intel SGX), and virtualized persistent memory
• Uses new UEFI-based boot architecture rather than the BIOS-based architecture used by generation 1

Note: Once you created virtual machine's generation you won't be able to change generation so, please considerations before you choose a generation. I would advise you to use Gen1 as it is right now.
