[Bug 912066] Re: /etc/fstab contains incorrect device for swap partition when no ephemeral disk present.

[Kiall Mac Innes]

This is a nova bug all right,  supplies the incorrect device name in the
ec2 metadata.

Nova supplies the following:

> 'block-device-mapping': {'ami': 'vda',
>                          'root': '/dev/vda',
>                          'swap': '/dev/vdc'},

When it should supply this:

> 'block-device-mapping': {'ami': 'vda',
>                          'root': '/dev/vda',
>                          'swap': '/dev/vdb'},

It seems to nova asks libvirt to attach the swap device at /dev/vdc, but
since libvirt+kvm simply uses the supplied device name as an ordering
hint, the device is actually attached at /dev/vdb
