nova-volume communication public eth0 change to private eth1
I have some issue about nova-volume network(public eth0 change to private eth1).
I use openstack essex version.
My Environment :
Public ip : 192.168.1.0/24
Private ip : 192.168.2.0/24
Controller has nova-volume partition.
public: 192.168.1.50 private:192.168.2.2
Create Volume-1 10G
Create VM-1: public: 192.168.1.151 private:192.168.2.50
Compute doesn't have nova-volume partition:
public: 192.168.1.51 private:192.168.2.3
Create VM-2: public: 192.168.1.152 private:192.168.2.51
When I attached Volume-1 into VM-1 for NFS.
VM-2 mount NFS into /mnt/ for transfer files.
The issue is:
What it always transfer files from public ip(eth0) not private ip.
Can I change from public ip to private ip(eth1)?
Because the public interface bandwidth will be occupied.
Does anyone have idea? Or some hint for me
Thanks a lot
