Hi Simon,
There is a bug: we can't pci-detach a statically-assigned (I mean: use the pci 
string in hvm config file) devices for hvm guest.
Accordong my limited experience, after a device is assigned to hvm guest, ioemu 
does write the correct vslots value into xenstore, but looks xend can't get the 
correct value somwhow.
Could you help to have a look? Thanks!
