vxlan - preparation not working / vmknic not created

Hello,

i´m trying to get vxlan working within a vcloud director 5.1 environment.

Within vshield manager i configured the sgement id and in the next step i try

to create the vxlan under connectivity. ProviderDC is not yet created.

I can select the cluster and my desired switch and start the installation. This takes

about 5 minutes and ends in state "not ready" and error.

During setup the portgroup is created but no vmknic within this.

On my esx hosts i see events "vib-module for agent not installed on host 172.... (vshield-vxlan-service)"

and "Agent activating" which end with error.

Tried basics like creating new dvSwitch, reboot Hosts, reinstall everything...

I upgraded my networking & security appliance to latest version as stated here:

http://www.virtualizationteam.com/virtualization-vmware/networking-virtualization-vmware/vcloud-networking-security-5-1-1-create-dvport-groups-but-fails-to-create-vmknic-interfaces.html

I also tried to install the agentpackage vxlan.zip manual via esxcli on all of the 3 hosts but still no success...

Anyone an idea where i can get deeper error message to find the solution, or perhaps a hint to the solution?

Regards,

Patrick
