[PATCH 0/2] conf: Don't generate clashing machine names for embed driver

Inspired by the talk here: https://www.redhat.com/archives/libvir-list/2020-March/msg00232.html Instead of using md5() and the first 6 letters of it, I've decided to go with SHA256 and 8 letters as this offers 16^8 = 4294967296 = 2^32 possibilities, which is the limit of inodes for ext4. If we ever hit a conflict, we can just use 9 letters of the hash.
