Subject [jira] [Commented] (CLOUDSTACK-5908) Fail to add VXLAN network to instance
Date Tue, 21 Jan 2014 08:51:19 GMT

Nux commented on CLOUDSTACK-5908:
---------------------------------

Hello Toshiaki,

Indeed this was the problem as Marcus Sorensen advised me on the ml, there was no IP address
set on the bridge, had no idea this is required but now it does make sense for it to be. More
tests to come.

Thanks for you help!
