In my experience this is because of double quotes around regexp and line that
contains backslash, it is treated as a string and do expand escapes.
You can avoid that by using single quotes instead, but then you need to escape
the single quotes in you regexp.
What I do is avoid quotes all together, to do that you need to write your
with_items in another style
with_items:
- regexp: ^(vif.*'mac=)((\w{2}:){3})((\w{2}:?){3})(.+)'$
line: \1\2AA:{{ 99 | random(start=10, step=1) }}:{{ 99 | random(start=10,
step=1) }}\6
backrefs: yes
- regexp: (^uuid)(?:[=\s']+)'(.*)'.*$
line: "{{ newid.stdout }}"
backrefs: no
- regexp: (^name)(?:[=\s']+)'(.*)'.*$
line: "{{ newid.stdout }}"
backrefs: no
This should work and the double quotes in the line must be there since { after
colon in yaml is treated as a dict.
