Hi, i'm using openstack (icehouse) with virt-manager (ubuntu 15.04 64bit on
the physical server) and 3 vms (controller, compute and network with
neutron and gre - centos 6.5 64bit on each vm). When I try to launch a new
cirros 0.3.4 image, i have an error on the compute node:

DEBUG nova.virt.disk.api [req-e98d3647-5bff-4524-8d3f-c3275f10f607
66713c43084e4163ad01a79d66f96276 bfd8576b0dae41a9bdd67b58e3c835a4] Unable
to mount image
/var/lib/nova/instances/5e0693fc-891a-43d4-be78-33ec47bc7b07/disk with
error Error mounting
/var/lib/nova/instances/5e0693fc-891a-43d4-be78-33ec47bc7b07/disk with
libguestfs (mount_options: /dev/sda on / (options: ''): mount: you must
specify the filesystem type). Cannot resize. is_image_partitionless

On the compute node I have:

virt_type = qemu


inject_partition = -2

Please, someone can help me? I cannot find a solution.

PS: I have a production environment with the same configuration and all
works well. I think the problem is related to the virtualized environment.
