The new virtio (http://kvm.qumranet.com/kvmwiki/Virtio) virtual devices which are available to provide PV drivers to KVM and other virt technologies don't seem to be showing up in hal. It looks like we just need to add support for the "virtio" bus
Created attachment 296524 [details] Support for virtio devices This seems to do the trick to add support for finding the devices. The disk still isn't found, but that looks like it's because we're missing the block symlink in the device directory ==> kernel problem.
And kernel patch for virtio disks to show up properly sent upstream.
Committed. Thanks. http://gitweb.freedesktop.org/?p=hal.git;a=commitdiff;h=e24b990287f81cc4c9394360e5ca477c0fd27993
