[Here are three patches which I committed already (by accident). I'm posting them for review instead here. If there are problems we can revert or amend what was committed.] This first patch changes the default exported disk to be /dev/shm/vhostmd0 (instead of /dev/shm/vhostmd/disk0). Having the intermediate vhostmd directory is problematic because there is no good place to change the permissions on this directory, and if the permissions aren't made more permissive that the default then libvirt will fail to start KVM-based domains.
