This patch contains a couple of misc fixes. HAL has separate 'block'
and 'storage' and 'volume' capabilities. Actual devices get the
'block' and 'storage' capability, while partitions get the 'block'
and 'volume' capability.
We have no need to expose partitions in this API, since we already
have a explicit storage pool impl for this. In addition, DeviceKit
will not expose partition information.
There are also a number of misc devices HAL shows that don't have
any capabilities in libvirt XML yet. Wierd embeedded components
from the chipset, and and sound devices. DeviceKit doesn't (currently)
expose any of these, and since we have no capability info for them
it is fairly pointless exposing them from the HAL impl in libvirt
either.
Thus, this patch does a couple of things
- Filters out any devices from HAL for which we have no capabilities
- Removes the 'block' capability, and list the block device name
in the 'storage' capability XML
- In virsh nodedev-list, alphabetically sort device names
If we find we want some of these devices we're filtering, we can
easily re-add them in future - I prefer to expose too little info
for now, than too much.
