Intermittant networking between reboots with opnsense VM and PCI nic pass-through

Hi all,

I've read that nic pass-though is the most secure way to virtualize a router/firewall. I followed this guide on the great proxmox wiki and was able to pass-thought a 4 port intel nic to a vm running opnsense (dell v pro 1000). It all works - in fact I'm typing up this post "through" the firewall right now!

The problem is this: When i reboot the opnsense vm networking randomly doesn't work. The boot sequence shows the machine finding the NICs and setting there state to "up" but sometimes the lan interface is un-pingable and the wan interface doesn't receive an ip though dhcp from my isp.

Could this be a host problem or a guest problem? I'm not even sure where to start googleing on this problem... i'll cross post this to the opnsense forum in-case it is a guest problem. Does anybody out their have any host side ideas about what could be causing this?
