I see.
You say if a guest has the following XML configuration,
"CAP_SYS_RAWIO" capability is automatically added to it, right?
<disk type='block' device='lun'>
Yes, that actually seems reasonable, especially since device='lun' is
brand new, and so far, is really the only reason that we'd need
CAP_SYS_RAWIO.
