We are running Vsphere 4 essentials plus on a two ESXi host system with shared storage. vCenter is running on a Virtual Machine http://www.vmware.com/vmtn/resources/798. High Availability is enabled our licence does not cover us for vMotion.
Currently the Vcenter VM is running on Host A we need to migrate the Vcenter VM to Host B for routine maintenance on Host A. With all the other VM on Host A we can carry out a cold migration, however this involves shutting down the servers obviously this cannot be done with the Vcenter VM.
We have found a very crude way of moving the Vcenter VM using HA if we disconnect the network from Host A HA will fail over the VM to Host B. This works however is very crude and not something we would like to do on in a live system.
Has anyone else come across this problem or know of a way of forcing a VM to fail over Hosts using CLI.
