Thanks. This looks close. I feel the output of the "list" commands are a
little awkward. For e.g.:
ovn-nbctl lb-list
UUID LB PROTO VIP
IPs
fc916e82-bace-4b86-9d1a-cee5fc796499 lb0 udp 192.168.1.2
10.0.0.10,10.0.0.20
fc916e82-bace-4b86-9d1a-cee5fc796499 lb0 udp 30.0.0.10:80
192.168.10.10:80,192.168.10.20:80,192.168.10.30:80
What would be nice is to aggregate the vips of a load-balancer and list it
without the first 2 columns. e.g:
UUID LB PROTO VIP
IPs
fc916e82-bace-4b86-9d1a-cee5fc796499 lb0 udp 192.168.1.2
10.0.0.10,10.0.0.20
udp 30.0.0.10:80 192.168.10.10:80,192.168.10.20:80,
192.168.10.30:80
The above style is used in many commands in the OVS repo, so it would be
nice if we are consistent.
Also, in the documentation please try to limit lines to less than 79
characters. I use vim and I have the following in my .vimrc to show the the
transgressing lines:
:syntax on
:colorscheme zellner
:match ErrorMsg '\%>79v.\+'
Please add the following incremental for your next version (please do read
it through once and fix any formatting or spelling issues).

- Creates a new load balancer named <var>lb</var> with the

can
- have multiple vips. We should assign <var>lb</var> a virtual IPv4

- (and an optional port number with : as a separator) and the
corresponding
- endpoint IPv4 addresses (and optional port numbers with : as
separators)
- separated by commas. The optional argument <var>protocol</var>
must be
- either <code>tcp</code> or <code>udp</code>. This argument is
useful when
- a port number is provided as part of the <var>vip</var>. If the
<var>protocol</var>

named
