network issue with multiple NICs

Hi,

I've installed Proxmox VE 2.2 on a Dell R420 server. The server has 2 network cards, the embedded dual port 1Gb (eth0, eth1) and a Dual port Intel 10Gb card (eth2, eth3). I have 2 networks, one public network (41.1.1.x, netmask 255.255.255.192) for management, etc. and a private network for storage traffic (192.168.10.x, netmask 255.255.255.0). The public network connects to 1 1Gb port (eth0) and the private network connects to 1 10Gb port (eth2). On proxmox I can configure both ethernet interfaces (eth0 & eth2) to work on their respective networks. From the console I can ping machines on both networks fine.

I then set up a KVM VM (CentOS 6.3) and configure 2 vistual network adaptors. vmbr0 (eth0) and vmbr1 (eth2). On the VM I set up net0 bridged to vmbr0 and net1 bridged to vmbr1.

Here is my /etc/network/interfaces file (proxmox):
My issue is that from within the VM I can only ping the public network 41.1.1.x and not the private network 192.168.10.x. What am I doing wrong?

Regards,
