Hi there, just after a bit more information, as to whether this needs doc text, and if so what was causing this problem, and what the fix is.

Thanks.

Comment 9 Fabian Deutsch 2013-11-29 09:34:56 UTC

Hey Charlie,

no we don't need a technote here. That's mainly backend stuff.

Comment 10 haiyang,dong 2014-01-07 07:01:40 UTC

Hey Fabian,
Not sure how to verify this bug, could you help this or i just need to check patch was merged into rhevh 6.5 base image.

Comment 11 Fabian Deutsch 2014-01-14 11:08:49 UTC

Hey Haiyang,

you can check this as follows:
1. Set netconsole host which is not reachable
2. Save page

Result:
No exception should be shown on the screen.

Comment 12 haiyang,dong 2014-01-15 05:37:24 UTC

Test version:
rhevh-6.5-20140110.1
ovirt-node-3.0.1-16.el6_5.noarch

Test as follow：
1. Set netconsole host which is not reachable
2. Save page

Test result:
No exception was shown on the screen when set netconsole with a unreachable server

so this bug has been fixed, change the status into "verified".
