I think  that I might have spotted the problem. This is a fresh install of
ACS 4.5 and Xserver 6.5 and I noticed that the vlans are not being created
in xenserver. The vlans are configured in ACS but they are not being pushed
to the xenservers. I am using openvswitch and not linux bridge on xenserver.

Subject: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException:
Communications link failure

Just trying a 4.5 deployment after moving my secondary storage to a
dedicated nic and vlan (it was on management) I checked the firewall rulls
that I am allowing traffic between the hypervisor network and the secondary
storage network. I can mount the nfs share of secondary storage on the
hypervisor.

 

I just sent my network admin to an email to make sure that ports were
assigned to the correct Vlan but I won't hear back from him until the
morning and I'd like to work on this tonight if you can give me some
guidance

 

Deployment error
