closedNIC Passthrough in Virtualized pfSense 2.5.1 Crashes Hypervisor
0%
Description
Running pfSense 2.4.5 in Proxmox with Intel NIC passed through was stable for several months. After updating to 2.5.1, the entire hypervisor began to crash, sometimes multiple times in a single day. The behavior was sporadic, but the longest uptime was less than 1.5 days, crashing 3 or 4 times over the course of 4 days. After moving the VM to another node, changing it to a “router-on-a-stick” and removing the NIC pass through, all systems have been stable for a week.
I’ve heard multiple others mention they are having similar issues with virtualized pfSense 2.5.0/1 with NIC passthrough as well, including in the Facebook groups and pfSense forum.
Unfortunately, they way in which everything is crashing, I’ve not been able to find ANYTHING in the logs.
