Public bug reported:

On a single-node devstack installation, on Ubuntu LTS 14.4, with the Xen
hypervisor.

To reproduce:
nova volume-create --image-id cirros-0.3.2-x86_64-uec --display-name vol-cirros 1
nova boot --key-name `hostname` --block-device source=volume,id=$volume_id,dest=volume,bootindex=0,shutdown=preserve --image '' --flavor 42 cirros

The instance cirros does not finish to boot, and `nova console-log
cirros` shows "I/O error" while accessing the block device.

console-log:
info: copying initramfs to /dev/xvda
[   79.327661] end_request: I/O error, dev xvda, sector 2
[   79.327678] Buffer I/O error on device xvda, logical block 1
[   79.327686] lost page write due to I/O error on xvda
[   79.327728] EXT3-fs (xvda): I/O error while writing superblock
[  160.463559] end_request: I/O error, dev xvda, sector 25154
[...]

Another way to reproduce would be to use `nova volume-attach` instead of
the --block-device option of nova boot.
