Hi,

I’m having an issue with TrueNAS (CORE/SCALE) running as a QEMU node in EVE-NG.

Problem description
• TrueNAS VM boots correctly
• It gets an IP address (static or DHCP)
• Ping works from multiple clients
• However, Web GUI does not load
– browser shows loading screen or hangs indefinitely
– happens from Windows and Linux clients
– tried different browsers

So network connectivity exists, but the GUI never fully renders.

Environment
• EVE-NG (bare metal)
• TrueNAS running as QEMU VM
• Network adapter: virtio
• Management access via browser from LAN
• No firewall in between (direct access)

What we already tried
• Verified IP configuration on TrueNAS
• Confirmed ping and basic connectivity
• Checked MTU consistency (no mismatch)
• Disabled TCP offloading on the client side
• Tested from different OSes (Windows / Ubuntu)
• Restarted middleware / services
• Rebooted VM multiple times
• Changed CPU type
• Changed NIC type
• Tested Clock setup for proper zone/time for all vm's

Observations
• Issue looks not like a routing or IP problem
• More like:
• virtio NIC / driver interaction
• offloading / packet handling issue
• GUI backend reachable but frontend requests not completing

Question

Has anyone seen TrueNAS GUI hanging on loading screen in EVE-NG, especially with virtio NIC?
• Is this a known incompatibility?
• Any recommended QEMU options or template tweaks?

Any hints or confirmed working setups would be appreciated.

Thanks.

try different qemu versions in the node settings. try a different true nas version.
