There was no entry in kern.log for AppArmor. Thanks I'll look at the qemu lists. On Tue, Jan 6, 2015 at 3:27 PM, Eric Blake <eblake@redhat.com> wrote:

Hello all, I'm trying to create an online internal snapshot to work with Cuckoo Sandbox. I keep receiving this -22 error below on my Ubuntu system and I'm out of ideas, been at it for a while so any help is appreciated.

That message comes from qemu (file a bug report with them for poor-quality error message; looks like someone forgot to convert a negative value back into a positive EINVAL errno value).
As for why qemu is seeing an EINVAL, I have to wonder if it is a case of AppArmor blocking access to a file. But that's weird, as internal snapshots don't normally need to open any additional files. At any rate, it's more likely to be a qemu bug than a libvirt one.
