Oracle Linux : 6.6
Grid Infra version: 11.2.0.4
Virtual Box : 4.3.28 (on Win 7 Host)
I am trying to Install a 2-node RAC in VMs created in VirtualBox. But the cluvfy check is failing for both my Public and Private networks with "No route to Host" error as shown below.
ping between both nodes work without any latency. passwordless ssh is configured succesfully.
I have a dedicated DNS server (10.194.135.185). nslookups of SCAN, Public and VIPs are working fine.
Googling didn't help much . Hence posting it here

#### Below is my network configuration.
I have created 2 virtual adaptors at host (Host-only network) .

Following are configuration files for network interfaces in each RAC node.
GATEWAY value in /etc/sysconfig/network-scripts/ifcfg-ethn file is set to the IP of virtual NIC adaptor at host (win7) level.
Node2 was cloned out of Node1 . So, the UUID of eth0 and eth1 remains the same for both the nodes . Hope this is not an issue because HWADDR (MAC ID) is different between the nodes.
