Hyper-V Daemon

[intersectRaven]

Feature Request

Please have a way to enable hypervvssd service in Talos.

Description

Currently, our backups are throwing warnings due to Hyper-V snapshots failing to create an application consistent checkpoint and instead creating a crash consistent checkpoint. I usually solve this on our other Linux based VMs by just installing hyperv-daemons and enabling the hypervvssd service which takes care of all the stuff but since I can't access the commandline I don't think that's possible currently.

Disclaimer: I don't have any experience with Hyper-V.

If that's a matter of running a daemon across the nodes, you can do that via Kubernetes DaemonSet (privileged one, I guess).

If that requires deeper integration, Talos offers system extensions and extension services:

• https://github.com/siderolabs/extensions
• https://www.talos.dev/v1.2/advanced/extension-services/

I can verify that you can run hyperv-daemons as a daemonset across the nodes and it works fine.

See my implementation for reference: https://github.com/willemm/hv_kvp_container
