Thanks for the ACK Matthias, but this is not really ready for commit,
this need progress in Spice acceptance in QEmu upstream and as Dan
pointed out privately this code need to be revamped to match the new
device addressing method in QEmu. But I wanted to rebase those patches
to make it easier once things speeds up on Spice front.
So not to be commited yet :-)
