sounds to me that you are trying to upgrade the KSU without upgrading the VM. It is my understanding that when upgrading a KSU you must also upgraded VM as well and when doing this you need to upgrade the VM first then the KSU.For example: if you have a KSU and a VM that are v.3.0 and you upgrade to v.4.1 on KSU it will not talk to the VM, however if you upgrade the VM. only to v.4.1 and leave the KSU at v 3.0 the VM will still talk to the KSU.
