SPICE - VNC Connection problems after migrating 2.2 to 3.0

Hi ,

I recently migrated one of my vm from 2.2 to 3.0.

I started the vm successfully but when I try to VNC or SPICE from the RHEV-M I get a dialog saying "Failed to connect to Server " for VNC connections and "Error Connecting to virtual machine using spice: The client could not connect to the remote computer . Remote Connections might not be enabled or a network problem is preventing your connection" for SPICE connections.

I already opened a case for this we,found out that the firewall is not an issue, we turned the iptables service off on the RHEV-M and attempted thte VNC/SPICE connection without success.

Now this problem applies to all vms that I have migrated, I don't know this is happening because of themigration or for some other reason.

Any clues?

thank you
