Ack, I'll send a v2 with only the parsing support (and the tangential
vzdump logging patch).

Regarding rewriting in pve8to9: I feel like it will be confusing to
users if there is a mix of suffixes in different guest configs. But
okay, I guess we can mention this as a known issue in the upgrade guide,
i.e. that the old suffixes for disks in guest configs meant powers of
1024 too (even if it's not an actual issue, but just ambiguity).

Alternatively, we could also add an UI patch to always display the new
suffix even if the config contains the old one?
