Re: [nv-l] Redirect ovw to virtual frame buffer
I think what you want to do is avoid
interrupting web console sessions... is that correct?
Keep in mind that netviewd is basically
ovw running as a daemon, with its display redirected to a virtual frame
You can run netviewd with a read-only
copy of the map by editing in the read only parameter to netviewd's lrf
file, and then re-register it to incorporate the parameter into the ovsuf
file via the ovaddobj command. Editing ovsuf directly is possible
and effective, but be careful and remember to update the lrf file too.
Our Knowledge Base article # 1121393 has additional information you
can use on this (attached).
Now that netviewd is using a read-only
map, you can forget about netview -dconsole, and leave it running for your
web console users to remain attached. You can bring up the read-write
map for administration anytime without disrupting your web console users.
However, should a web console user attach to your read-write map
while you are adminstering, that web console will be disrupted when you
close your map.
Map updates, of course, are dynamic
on the read-write map, but not on the read-only, so you may wish to establish
a recycle schedule of your netviewd daemon depending on how dynamic your

When Xvfb runs, it runs on a certain display(NetView usually uses
:2 as the display). This is also normally present on the command
line. So a ps -ef | grep vfb should let you know which display it
is running on. To redirect NetView to that vfb, you can:
1) set your display and then run NetView
2) I think you can run NetView with a -display option, ie:
netview -display netviewserver:2
That should do it for you.
