PCI Passthrough for Digium TCE400P Codec Card Not working

trying to use a Digium TCE400P Codec card on a Virtual instance using the following information:

lspci <enter>

02:08.0 Ethernet controller: Digium, Inc. Wildcard TCE400P transcoder base card (rev 11)

lspci -n <enter>

02:08.0 0200: d161:8004 (rev 11)

virsh nodedev-list | grep pci

pci_0000_02_08_0

printf %x 02
2

printf %x 08
8

printf %x 0
0

bus='0x02'
slot='0x08'
function='0x0'

# virsh edit vmanager
<hostdev mode='subsystem' type='pci' managed='yes'>
  <source>
      <address domain='0x0000' bus='0x02' slot='0x08' function='0x0'/>
  </source>
</hostdev>

I have SELINUX disabled at this time.

virsh start vmanager I get the following error message:

[root@twins qemu]# virsh start vmanager
error: Failed to start domain vmanager
error: internal error Process exited while reading console log output: char device redirected to /dev/pts/2
Unable to assign device: PCI region 1 at address 0xdf1fe000 has size 0x400,  which is not a multiple of 4K
qemu-kvm: -device pci-assign,host=02:08.0,id=hostdev0,configfd=23,bus=pci.0,addr=0x6: Device 'pci-assign' could not be initialized
