In virt-sparsify 1.26, you could also use virt-sparsify --in-place option to do the sparsification in place (this is also much faster). Also if you use virt-sparsify in default (copying) mode, then it can do the format conversion (see --convert option in the man page).

virt-sysprep can customize the image how you want. (virt-builder) can create the image from scratch with customizations.

@kemra102: That's a successful run of libguestfs-test-tool so you should be good I think.

With the latest version of openstack, if libvirt_inject_partition is -1 then libguestfs should use inspection to determine the correct mounts. So you should check /etc/nova/nova.conf to find out what that setting is.

There are two different errors in the discussion above. The first one is:

mount_options: /dev/sda on / (options: ''): mount: you must specify the filesystem type

which means that libguestfs could not detect the filesystem in the disk image (and it's probably looking in the wrong place too).

My Cirros 0.3.0 disk image here has a partition containing an ext3 filesystem:

$ virt-filesystems -a cirros-0.3.0-x86_64-disk.img  --all --long -h
Name       Type        VFS   Label          MBR  Size  Parent
/dev/sda1  filesystem  ext3  cirros-rootfs  -    31M   -
/dev/sda1  partition   -     -              83   31M   /dev/sda
/dev/sda   device      -     -              -    39M   -

But for libguestfs in Nova to find this, it has to be able to inspect the image, which also works for 0.3.0:

$ virt-inspector -a cirros-0.3.0-x86_64-disk.img
<?xml version="1.0"?>

This didn't work properly with CirrOS 0.3.1, but (that bug has now been fixed upstream).

The second error is:

Error mounting /dev/cinder-volumes/instance-0000001d_disk with libguestfs (/dev/cinder-volumes/instance-0000001d_disk: Permission denied

which looks like a straight permissions error. libguestfs needs sufficient permissions to be able to read and write to the disk.

What is the complete, unedited output of libguestfs-test-tool?
