[Qemu-devel] Question about xen disk unplug support for ahci missed in qemu

[Fabio Fantoni]

I added ahci disk support in libxl and using it for week seems that was 
ok, after a reply of Stefano Stabellini seems that xen disk unplug 
support only ide disks:

Today Paul Durrant told me that even if pv disk is ok also with ahci and 
the emulated one is offline can be a risk:

I tried to take a fast look in qemu code but I not understand the needed 
thing for add the xen disk unplug support also for ahci, can someone do 
it or tell me useful information for do it please?

Thanks for any reply and sorry for my bad english.
