Description Markus Stockhausen 2013-09-22 06:44:02 EDT

Description of problem:

Using IPoIB in connected mode allows MTU of 65520. Web admin interface allows only MTU of 9000 or less.


Version-Release number of selected component (if applicable):

Ovirt 3.3.0-4


How reproducible:

100%


Steps to Reproduce:
1. create new network
2. enable override mtu flag
3. enter values beyond 9000
4. try to save

Actual results:

mtu field gets a red frame (showing values are not accepted)


Expected results:

values of up to IPoIB connected mode 65520 bytes should be allowed.

Comment 1 Lior Vernia 2014-01-20 06:45:51 EST

The maximum value is now taken from the engine config value 'MaxMTU'; if it is absent, then the default will remain 9000.

Comment 2 Andrew Cathrow 2014-01-20 11:43:27 EST

Lior, is this config accessible in the engine-config tool?

Comment 3 Lior Vernia 2014-01-21 03:12:12 EST

Andrew, I thought it was but it isn't, so effectively this isn't exposed to users. Discussed and gonna lift the MTU limit altogether.

Comment 4 Lior Vernia 2014-01-22 08:23:36 EST

Over-automation.

Comment 5 Sandro Bonazzola 2014-02-07 06:20:10 EST

Fixes should be in ovirt-3.4.0-beta2. Assignee please check.

Comment 6 Martin Pavlik 2014-02-12 03:47:37 EST

verified with
oVirt Engine Version: 3.4.0-0.7.beta2.el6
vdsm-4.14.1-3.el6.x86_64

MTU 66000 was set in engine, host which was not capable of such MTU was correctly marked as network not synchronized

Host dell-05's following network(s) are not synchronized with their Logical Network configuration: huge_MTU.

Comment 7 Sandro Bonazzola 2014-03-31 08:27:48 EDT

this is an automated message: moving to Closed CURRENT RELEASE since oVirt 3.4.0 has been released
