While it is pretty clear how to put info ab= out NIC hotplugging in the osinfo, here are a few issues when trying to int= roduce the same concept for disk hotplugging. Some disk interfaces do not support hotplugging at all (like IDE), some of = them support it in the x86_64, but not in the ppc64 architecture (like the = VirtIO blk) and others support it in both architectures (like VirtIO SCSI).= There is also a ppc64 specific controller called SPAPR VSCSI, which suppor= ts it too. So, how do you propose a syntax to cover all these cases? I thought about something along the lines of: os.{id}.devices.disk.hotpluggableInterfaces =3D VirtIO_SCSI, VirtIO Thanks, Leonardo Bianconi/Vitor de Lima/Gustavo Pedrosa --_000_EF26FC1776F7FF46BFC072393EFD13A29A4FC8SERV070corpeldora_ Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" xmlns:o=3D"urn:schemas-micr= osoft-com:office:office" xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" xmlns=3D"http:= //www.w3.org/TR/REC-html40"> <head> <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3Dus-ascii"=
