What I am referring to is the following:

1) Boot up host.
2) Start up domU - works every time now with <= 2GB of RAM (any more 3GB 
sometimes works. 4GB+ hardly ever gets to the login screen)
3) Shut down domU
4) At this stage, starting up the domU usually works. Maybe half of the 
time it BSODs or loses the USB devices (they show up with a yellow 
exclamation mark in device manager - ejecting them doesn't help).
5) Repeat from 3) At this point things never get past a BSOD and the 
only way to get the domU working again is to reboot the host.
This should now probably become a couple of new threads:
1) VGA passthrough BSOD-ing with a domU with more than 2GB of RAM
2) domU reboots cause USB controllers to become unavailable
