Doing autodetection in Exact Audio Copy inside an XP VM causes the entire system (including the host) to hang

1) Install XP in a VM
2) Configure a host CD drive for passthrough to the VM
3) Install EAC in that VM
4) Start EAC
5) Put any audio CD in the drive
6) Do the configuration wizard. Pick "prefer accuracy"
7) Start autodetection
8) When it reaches C2E, the whole system hangs

No VT-switch, no killing X, no HDD activity when pressing the power switch -- it freezes hard.
