Proxmox 7.2: Disconnects from Host Every Few Minutes When Using VirtIO, e1000 Works Fine
-
I know this is most likely the problem is on the Proxmox side, but I wanted to bring attention to this issue. Maybe someone here has encountered it before.
I don't think that the current version of pfSense and Proxmox require disabling hardware checksum offload and hardware TCP segmentation offload on the physical linux (=proxmox) side, unless there is a new bug.
-
Update: maybe this IS a pfsense issue (more specifically, FreeBSD 12.x), despite q35 chipset not being in use in my case?

@pitchfork
I"ve no issues on KVM with i440 chipset and hardware checksum offloading enabled. -
If there is indeed a FreeBSD bug, since Proxmox doesn't offer virtio-transitional, I might have to use another adapter: vmxnet3 works so far, speeds are not like virtIO but it allows me to wait longer for a solution.

bueller? bump?

Upgrading to pfSense 23.01/FreeBSD 14 (from 22.05/FreeBSD 12), solved the issue. Don't know if it was pfSense or FreeBSD, but it surely wasn't a Proxmox issue.

Hi,
I have pfSense 22.05 virtualized in proxmox 7.3: I had strange network performance issue with it and also with a plain debian install.
Turned out issue was NIC used (intel 210) belonged to a PCIE card, while in proxmox grub I had pcie passthrough option active: once removed all back to normal.
Not sure if that could be related though
