    Name mismatch - `VM_NAME_DISALLOWED_PATTERN`, `vmNameAllowedChars`. Also not obvious it's
a regex, figured it out after looking at the default value.
    Prefer to have a white-list rather than a black list. I see that's a bit tricky to do
with regexes. Could iterate through the characters of the string and match each one against
the regex. wdyt?
