Sorry for the delay - here are those instructions:
You'll want to execute 'virsh edit domname' as root to edit your domain's
config file, and then add this XML after the 'pci-bridge' controller block:
<controller type='pci' index='3' model='pcie-root-port'>
<target chassis='1' port='0x1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x1c'
Then scroll down to the <hostdev> block for your GPU, and alter it to use
the controller (bus 3) we just created:
<hostdev mode='subsystem' type='pci' managed='yes'>
<address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
<address type='pci' domain='0x0000' bus='0x03' slot='0x00'
