Great! Nice to see that my hopes^Wexpectations about this being really
not that much work/code are being met.

As mentioned off-list, some way for configuring the base defaults for
disks/mountpoints and networks without having to already explicitly
specify the single would be nice to have.

As talked, having a net-defaults, scsi-defaults, mp-defaults, ...
property supported by the respective VM/CT config itself could solve
that and even provide an additional feature.
The values decoded there would be merged with the actual instances,
e.g., scsi0, scsi1, ... or net0, net1, ..., on start.
There might be a few edge cases, and me might not want to support
every option (e.g., a default serial for all disks is rather counter
productive), but otherwise this could be a nice way to encode things
like "discard=on,sdd=1" for all (future) scsi disks, be it for a
specific VM or CT, or also in a profile.
