We hava a couple of esxi hosts that are connected to a vcenter server.
The esxi hosts all have public ip addresses. Now we have added a vkernel with an internal ip adress for each host. This is done so that the vms can be replicated over the internal network and so that the host can be managed over the internal network. The vcenter server has also an ip address in the same internal subnet.
The external ip's are used to backup the vm's to an external location.
So each host has an external and internal ip.
Since we did this change, we get in aprox. 20 % of the vm replica's an error that says "an error occured while communicating with the remote host". This happens randomly, so the vm's with error in one replica job can be successfully replicated the other time. So it's not the same vm's/hosts that generate errors.
Physically, alle the nic are connected to the same switches. There are no vlans yet.
Thanks in advance.
