hello, I am trying to setup a Proxmox Host with PfSense running on it.
this is a brand new setup, using Lenovo Think Center M58 with Intel Core Duo CPU
it's support VT-d etc. I checked.

now, I have a new Proxmox VE 4.4 setup using ZFS RAID-1 on 2 SSD.
just installed and updated.

I am creating the new VM (KVM)
dual core
4GB RAM (I know it is a lot so I set it as range 1GB-4GB)
16GB HDD(qcow2)
2 virtuO nics using vmbr1(WAN) and vmbr2(LAN)
WAN is dhcp as It will get the IP from my cable modem, now it gets an IP from my router
LAN is static "192.168.5.20"

the proxmox "/etc/network/interfaces" is like this:
Code:
auto lo
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

iface eth2 inet manual

auto vmbr0
iface vmbr0 inet static
    address  192.168.5.30
    netmask  255.255.255.0
    gateway  192.168.5.1
    bridge_ports eth0
    bridge_stp off
    bridge_fd 0

auto vmbr1
iface vmbr1 inet dhcp
    bridge_ports eth1
    bridge_stp off
    bridge_fd 0
  
  
auto vmbr2
iface vmbr2inet manual
    bridge_ports eth2
    bridge_stp off
    bridge_fd 0



Proxmox is fine and on the network
but VM behaves strangely.

it finds the nics, allows me to set them up but I can not see or reach them from anywhere, not even the host.

the VM is not on the network and not on the internet, even though all looks to work..
I have seen this behavior on my test setup but I though it was do to the fact that my test was a nested virtualization i.e. my proxmox host was a VM running in Hyper-V host.
but now I am not sure.

OK , this has somehow resolved it self.
when I boot it up last night and started VM it had the proper IPs and was on network.
I was able to reach the webui for VM and set it up properly.
nothing changed as far as I can tell but it start to work.
