Hello everyone, I’m fairly new to Proxmox and struggling with my homelab setup. I have two machines running Proxmox 9: an HP EliteDesk 800 G5 Mini (Core i7-9700) and a Dell OptiPlex 7070 Micro (Core i3 9th gen). I’m running into several issues and would appreciate your insights.
- Networking Issue on EliteDesk: I have two VMs (both Ubuntu Server 24.04 LTS) on the same bridge (default vmbr0, I haven’t modified any network settings in proxmox). If I stop or shut down one VM, the other loses internet connectivity. I can still access the applications from my home network using IP address (192.268.x.x).
Backup Setup on OptiPlex: I’m running a Proxmox Backup Server VM with Backblaze B2 as an S3 datastore. This is working fine so far.
Backup Problems on EliteDesk: I’m using default LVM-thin for VMs. Backups take a very long time and often freeze at 1-2%. Shutting down the VM cleanly afterward is nearly impossible. I’ve tried both Stop and Snapshot modes, but the issue persists. When a VM becomes unresponsive, it triggers the networking issue above. Would switching to ZFS help? If so, how can I migrate without losing any data?
Hardware Acceleration for Jellyfin: On the EliteDesk, I’d like to enable hardware acceleration for a VM running Jellyfin (in Docker) using the i7-9700’s UHD 630 iGPU. Can anyone recommend a clear guide specific to this CPU? The Proxmox documentation isn’t very detailed for Intel GPUs.
The networking issue is the most frustrating. Has anyone encountered similar bridge problems? Any advice on fixes or next steps would be greatly appreciated. Thank you!
@mitexleo this is odd, if everything in in a bridge, then a physical port to your switch/router should be your uplink. Check for MTU mismatches, and CRC errors on the cabling.
I don’t think MTU mismatch or CRC error is the root cause. So far, I haven’t modified any proxmox settings. I’ve updated the post. ❤️
