Hi everyone,
We proposed some changes in how to query if an operating system supports hotplug, then Itamar suggested that disk hotplugging and NIC hotplugging could be separated from each other. While it is pretty clear how to put info about NIC hotplugging in the osinfo, here are a few issues when trying to introduce 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 supports 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 = VirtIO_SCSI, VirtIO
Thanks,

"storage" is a better term than "disk" so:
why? this is about a vdisk, isn't it? well a vnic and vdisk are the building blocks in the end. so either we use vnic vdisk etc or storage,network etc for all
os.{id}.devices.storage...
maybe in the future we may expand the metadata model to hold devices and hook it to an OS
device.{id}.... os.{id}.devices={deviceId}
just a thought, its unnecessary for now.
