    Proxmox V6 Servers freeze, Zvol blocked for more than 120s

    I didn't get a chance yet to trigger this on my box (accidentally moved a VM to the server that I can't reboot until the weekend, sorry!), however, I noticed that at least in my case, this doesn't seem to be I/O related: - I accidentally managed to move a VM (2TB of data) to the server, no...

    Turning on the PVE Firewall stops VM / LXC connectivity

    I actually just hit this exact issue today as well, on a cluster of 3 servers hosted in Hetzner, accessed/managed via a Hetzner vSwitch. Enabling the firewall (even with ACCEPT/ACCEPT at the Datacenter level) resulted in losing connectivity to all VMs and management via other (non-local)...
