When setting up the clustering, while configuring the master node, there is a key being created which is then used to encrypt the communication between both cluster nodes.
Especially in virtual environments, when clustering the Check_MK virt1, the generation process of this key might "hang" for a long time, as there are not enough random information (entropy) available to create the key.
We have now fixed the issue by ensuring there is enough random information available. This is done by using the daemon haveged, which feeds the kernel with enough random data.
