Piotr,
According to our checks engine succeed connecting VDSM through ipv6 once the
work you've reminded has been done. So it looks like jsonrpc is agnostic to
IP layer it uses underneath.
I never tested it with ipv6 but looking at java internals that I used
and it accepts host as
specified in RFC 2732 or RFC 2373.
It looks that it should work out of the box.
Could you please elaborate on why do you think that we break
backward
compatibility.
I suggested to add Address type which would hold both address types so we
could use it in many places. This change would break backward compatibility.
If you compare the wiki to vdsmapi-schema.json file, looks like the
last
isn't updated for some time and needs to be updated according to the actual
code.
Type extension would not break backward compatibility but it would introduce
bunch of optional parameters. I think we could do better.
We add dhcpv6 in order to allow user to configure v6 stack
independently
from v4 one. That could be useful especially in a transition period, when a
user have fully configured ipv4 and would like to try using ipv6 and he
hasn't configured his DHCP server for v6 yet.
I would add that to new address type. What do you think?
Regards,
Yevgeny
