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.

The newer versions of libvirt indeed do not allow duplicate storage
pools pointing to the same server / directory / mountpoint.
I think this is caused by the Secondary Storage pool which is not
cleanly removed.
I haven't seen this behavior with the current master and libvirt 0.10.0.
I think (can't remember) I fixed something regarding this, but I'm not
sure though.

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 )
