there any post install steps or upgrades? I'm thinking of setting this up

In case anyone runs into such a scenario in the future, here's what this
turned out to be. In /etc/sysconfig/network the GATEWAY from the source VM

What that statement means is if you explicitly define a dedicated storage

In order to use OVS, you need both the virtual switch and the control
plane. Those messages largely boil down to "We can't find an appropriate
control plane for your chosen network topology and hypervisor." This then
raises the questions of which control plane are you attempting to use, and

Importantly, if you're in a multi-hypervisor setup, you need to account for
what'll happen when all clusters of a hypervisor type go down. In your
case, if the KVM cluster goes down and you've pinned the systems VMs to the
KVM cluster, then CloudStack won't be able to restart them on either

- Is this going to be NFS or iSCSI (I've used EQL with iSCSI)?
- Do you require a separate storage network on XenServer to access the EQL,
or is it accessible from the same network as the management server?
- Is you EQL on the XenServer HCL, including the firmwar
