    net: MTU should be an integer all over VDSM.
has inadvertently broken existing Engines (I thought that they could handle both str and int). However, if we fix this in ovirt-engine-3.6.2, we can keep the Vdsm-side patch, since upcoming Vdsm is not expected to be manageable by pre-3.6 Engines.
Comment 3 Simone Tiraboschi 2016-01-07 13:00:57 EST
Did you backported to 3.6.2?
Comment 4 Yevgeny Zaspitsky 2016-01-07 13:13:55 EST
AFAIK the problem was caused by the a VDSM change in master that wasn't backword compatible. Thus the problem has been fixed in master only. Also danken plans reverting the change in VDSM, so I'm not sure if the change has to be back-ported to 3.6.
Dan, what's your opinion on that?
Comment 5 Dan Kenigsberg 2016-01-08 03:43:15 EST
Vdsm is already fixed on master by https://gerrit.ovirt.org/51164

I *wanted* to backport your fix to 3.6.2, but now it is too late. We'd have to carry the string mtu to 4.0.
