Review request for cloudstack, Marcus Sorensen and Toshiaki Hatano. Repository: cloudstack-git Description ------- Linux vxlan interface doesn't accept VNI:16777215. https://github.com/torvalds/linux/blob/master/drivers/net/vxlan.c#L2140 As far as I read internet draft ( http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-05 ), 16777215 is a valid VNI, but it cannot be used in Linux now. This patch decrements MAX_VXLAN_VNI to 16777214. Diffs ----- server/src/com/cloud/network/NetworkServiceImpl.java 61c070a Diff: https://reviews.apache.org/r/15012/diff/ Testing ------- I confirmed VNI validation works by specifying 16777215-16777215 to id range via add zone wizard. Thanks, Yoshikazu Nojima
