I have got GPU passthrough working on 14.04 with Win10 guest using the very helpful post here

It doesn't seem to matter how I shutdown the end result is the same. The guest closes and after a few seconds virt-manager disconnects giving the message
I've increased the logging in libvirtd.conf but see no error or warning messages. Same is true of syslog and kern.long
Other symptoms include:
Any ideas? I've been find to find a solution for this for a couple of weeks with no joy
