This patch is a only a fast draft for testing.

Some tests result:
At xl create cdrom empty or not  are both working, xl cd-insert is
working, xl cd-eject seems working but on xl command in linux hvm domU
return qmp error of "Device 'ide-N' is locked", in windows 7 instead
don't show the errror.
xl block-attach seems working correctly and xl block-detach works
correctly with linux hvm but not with windows 7 (seems block the disk
remove, I don't know if do the same without this patch)
Scsi disk case not tested for now.

Any comment is appreciated.
I think what's missing in this changelog is why we want this patch --
what's the advantage?  Was some of the functionality above not working
before, for example?


Add of ahci support require new -device parameters, I tried the change also all other cases to have the same. Is there also rare case of possible problem using old parameters on part of things (disks, network, audio and older usb if I remember good) but I not remember the example case, was found by another user. With this patch I'm trying to maintan full compatibility but probably there is something that I don't know that must be changed or may changes with this.
