There''s no need to preserve this abstraction; it used to let us use hardware crc32c support directly, but libcrc32c now does that for us through the crypto API -- so we''re already using the Intel crc32c acceleration where appropriate, without having to do anything special. As is right and proper. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> --- fs/btrfs/crc32c.h | 29 -------...

It doesn't appear to be using any kernel modules. I would have expected to see output such as this: supermin: internal insmod virtio.ko It seems as if you might not be setting SUPERMIN_MODULES; or maybe you

After failing to get things to work on a Ubuntu 14.04 host I build a fedora 21 environment to see if Ubuntu may have been the problem and didn't get quite as far so here's an official report per the FAQ directions: - Trying to get guests to build and have network access so package management actions can be done before uploading to openstack image service. - I ran ./run virt-builder
