vCMP and Trunk configuration

My issue also relates to the mentioned thread topic, therefor I place my question here as well instead of starting a new thread.

We have a cluster out of 3 BIG-IP 5250v using vCMP. The hosts are running on 11.5.4 HF2 and the guests on 12.1.0 HF1. Currently we have guest1 with 4 cores assigned and guest2 with 2 cores (2 cores free for later use). On the hosts we created a trunk for interfaces 2.1 - 2.4. This trunk is available for all three guest2-instances, but only for one guest1-instance. Not sure if this is related to the issue, but guest1 is currently not yet in use and only has HB-VLANs assign, which are not part of the trunk. Guest2 has already several VLANs assigned, which were part of the trunk. The guest1-instance where the trunk is available is the Active one.

So the question is, did I something wrong, is there something missing, is this normal and how can I fix this?

If you need any more information or have ideas what I should check or test, please let me know.

Thank you!

Ciao Stefan :)
