I am running a Server 2016 Hyper-V host. On the host I have multiple Windows and Linux VMs running as guests. The Linux VMs are Ubuntu 16.04 Server-based. To simplify administration, I back up the Windows VMs in one backup job and the Linux VMs in a second, separate backup job. I am receiving the following in the job log for the Linux VMs:
V-79-40960-38528 - The Hyper-V subsystem has reported that the Hyper-V Integration Services (HIS) inside the virtual machine do not match the version expected by the Hyper-V host. An offline backup of this virtual machine has been performed, update the Hyper-V Integration Services to ensure online backups can be performed whenever possible.
I have de-selected all GRT-related options for the job under Backup Options-->Virtual Machines-->Virtual Machine Granular Restore Technology Settings. I have Instant GRT enabled under Backup Options-->Instant GRT (the default).
Also, I have installed and upgraded both linux-tools and linux-cloud-tools packages in the VMs. I still receive the error.
Any help would be appreciated.
Yes, Ubuntu 16.04 is on the SCL for the Linux agent. However, seeing as these are VMs and being backed up via the agent for Hyper-V, the BE agent for Linux is not installed within the virtual machines. I suppose I could try installing the agent for linux within the VM, though I don't see how this would help?
You could install the Linux agent and backup that way - that would probably be considered as a workaround though as you are changing the backup method (agent-based backup vs virtual-machine level backup).
Just curious to understand if you have opened a support case for this issue?
