[Bug 591469] [NEW] virtio block devices names are not recycled

[Scott Moser]

Public bug reported:

I'm playing with eucalyptus, and attaching and detaching a block device as a virtio (bug 588410)
$ euca-attach-volume  --instance ${inst} --device /dev/vdc ${vol}
VOLUME  vol-5EC30651

Then,

$ euca-detach-volume ${vol}

The device names start as /dev/vda and go through to /dev/vdz and then
to /dev/vdaa ...

The names are not recycled it would appear.  In other buses (scsi) I'm
used to the device name being recycled.

This can most likely be re-created without eucalyptus, using only kvm,
but I dont' have those steps right at hand.
