Hi ,

When  you create ( an account)  your first user VM , a router VM comes up too 
which is named like r-4-VM. That is why you see two VM's listed when you run 
virsh list command  on the hypervisor.  Regarding the libvirt error , it seems 
the libvert version 0.9.12 storage driver  doesn't support duplicate underlying 
storage.
I am not sure if it is supported for the later versions . You'll have to check 
that out (http://libvirt.org/news.html )

Regards,
Pranav

Subject: source pool conflict

Hi Everyone,
             I'm running into a libvirt error on trying to instantiate a second 
user VM. The first VM gets instantiated successfully, although for some reason 
I see 2 VMs started up when I run 'virsh list' on the hypervisor, one with the 
name r-4-VM and the other with the name 1-2-3-VM.

Configuration:
Running Cloudstack 3.0.2 release versions on both my hypervisor (centos
6.3) and my management server (ubuntu 10.04).
libvirt 0.9.12
libvirt-java 0.4.8

The error I see in the libvirt logs :
 error : virStoragePoolSourceFindDuplicate:1748 : operation failed: Storage 
source conflict with pool: '85b9025f-b559-47e1-b02c-17aea4b95822'


Any guidance would be appreciated.

--Gautam
