<div class="PlainText">Hi,<br>
<br>
When someone calls nova volume-attach or the
block-device-mapping <br>
parameter at boot, it is possible to specify a device name
for the <br>
guest. However I couldn't find any guest OS which would
honor this. E.g. <br>
with libvirt/kvm, if the guest has two virtio disks already
(vda and <br>
vdb), specifying vdf would be ignored and the disk will be
attached as <br>
vdc in the guest.<br>
I propose to deprecate this option and at boot where it is
not optional <br>
to accept only auto as an option.<br>
<br>
Best regards,<br>
<br>
Geza<br>
