If we want to use IPv6 address with bootstrapping and converge.
We should use address syntax below.
## Enclosed in []
$ knife zero bootstrap [::1] -N v6vm -x vagrant -P vagrant --sudo
## Append ssh port to tail of string.
$ knife zero bootstrap [::1]:22 -N v6vm -x vagrant -P vagrant --sudo
## Set scope
$ knife zero bootstrap fe80::a00:27ff:fe60:59e0%en0 -N v6vm -x vagrant -P vagrant --sudo
And I recommend to use knife_zero.host to ssh attribute.
$ knife zero converge "name:v6vm" --attribute knife_zero.host -x vagrant -P vagrant --sudo
