Sudha Ponnaganti reopened CLOUDSTACK-4617:
------------------------------------------


This is still happening with Xen 6.1 and seems to be specific to this version 
of Xen.  
                
> Xenserver 6.1 - Add host succeeds but gets into Alert state due to "Unable to 
> create local link network". It remains in "Alert" state for a while and then 
> gets to "UP" state.

> Xenserver 6.1 - Add host succeeds but gets into Alert state. It remains in 
> "Alert" state for a while and then gets to "UP" state.
> Steps to reproduce the problem:
> In my case I already had 1 zone.
> Create another advanced zone with 1 Xenserver host.
> As part of zone creation wizard , provide all the values for zone creation 
> including primary and secondary storage details.
> Primary storage creation fails with error - "Failed to delete storage pool on 
> host"
>  Following exception seen in management server logs:
