Bug Description

Binary package hint: hw-detect

If a KVM is guest is started with virtio block devices the installer detects Serial ATA Raid devices. Booting the guest with the *same* files but using ide block devices doesn't show this message.

The output of the command "dmraid -c -s" run in the guest during installation is different:

For a guest with a virtio block device:

# dmraid -c -s
no block devices found

For a guest with an ide block device:

# dmraid -c -s
no RAID disks
