Be aware in RAID0 if one of the HDD fails, the content on both will be lost lost.

Sounds like you’re passing the physical HDDs to the VM instead of creating a new virtual HDD file in your proxmox pool.

If you don’t mind me asking, what are you trying to do with your VM?

In terms of services I use the most I guess it would be these:

• OpenHAB + HABapp + zigbee2mqtt + mosquitto (home automation)
• Foundry VTT
• piHole (DNS)
• OpenMediaVault (NAS)
• Grafana + Loki + Prometheus (monitoring)
