I updated VM to remove CD Drive and the VM lost network connection when rebooted. On connecting to host only loopback up, e0 doesnt exist.   Reverted back to beta 25 and update VM template server works again.   Upgrade to Beta30 server still works unless updated.   Diags attached before and after update on B30.   let me know if you need me to do any further tests as easy to recreate.   further info if i create a new machine from scratch it works
